Today we’re going to be talking about serpentine belts for our Christchurch New Zealand customers. Let’s start by talking about the accessories that are driven by the serpentine belt. First is the alternator. That’s the device that makes electricity to power the vehicle and recharge the battery. Then there’s the air conditioning compressor that makes cool air for you while you're driving around Christchurch New Zealand in the summer.
The power steering and power brake pumps are driven by the serpentine belt in most vehicles. Those pumps make the pressure that assists your steering and braking.
In many vehicles, the water pump is driven by the serpentine belt. The water pump is what circulates the coolant that protects your engine. In some cars around Christchurch New Zealand, the water pump is driven by the timing belt.
The radiator cooling fans on some vehicles are also driven by the serpentine belt. Some have separate electric motors. That’s really a lot of work for one belt.
But modern engine design has a single belt that snakes around the front of the engine and drives most if not all of these accessories. Serpentine belts do a lot of work, but they’re tough and can last for thousands of miles.
Just how long will they last? That’ll vary for each individual car in the Christchurch New Zealand area. Your manufacturer will have a recommendation for when it should be changed, but it could need it sooner. The good news is that a visual inspection can reveal a belt that’s getting close to failing.
Oil Changers can look at the belt: if it has more than three or four cracks per inch it needs to be replaced. A deep crack that’s more than half the depth of the belt - replace. Frayed, missing pieces, a shiny glazed look? It’s out of there.
What’s involved in replacing the belt? First the old belt is removed. Then a new one is fitted around all the pulleys for the accessories and the drive. There’s a special pulley called a tensioner.
This pulley is mounted to the engine block with a spring loaded arm. Its job is to apply the correct amount of tension to the belt to keep it from getting loose and maybe slipping off. Because the spring in the tensioner pulley wears out, AutoNetTV recommends replacing them at the same time as the belt. It just makes sense.
What are the warning signs that there’s a problem with the serpentine belt? You may hear a squealing sound from under the hood when accelerating around our Christchurch New Zealand streets. A loose belt might give you a slow, slapping sound.
What do you do if your belt breaks? If you’ve actually had that happen on our local Christchurch New Zealand freeway, it can be a little scary. Often the first thing you notice is that you have no power steering or power brakes. Don’t panic – you can still steer and brake, but you’ll have to do the work. It’ll be harder to steer and you’ll need more time and effort to stop, so plan accordingly.
Your dashboard will light up will all kinds of warnings. You’ll see a warning about your cooling system if you have a water pump that’s driven by the serpentine belt. This is very critical because without your cooling system working, your engine will overheat. If you don’t stop you’ll have massive engine damage, maybe to the point that you need a new engine. Pull over as quickly as you safely can. Open your windows and turn the heater on full blast to provide a little engine cooling and pulled over as soon as possible.
The battery light will come on because the alternator isn’t working. If your car’s water pump isn’t driven by the serpentine belt, you’re not in danger of overheating so you can drive a little further if necessary. But the battery will run down to the point where the car won’t run and will just shut off. You don’t want that to happen while you’re driving in our local Christchurch New Zealand traffic.
Remember, this does not have to happen if you replace your serpentine belt on schedule. Ask your technician at Oil Changers to check your belts and hoses from time to time so you can take care of them if they need to be replaced prematurely.

Engine Air Filter
Posted August 4, 2010 2:29 PM
You may have found yourself in the following situation: You go to get your oil changed and the service adviser recommends you get a new engine air filter. You say yes, but because you didn't know what an air filter is or what it does, you were too embarrassed to ask.
First of all, you did the right thing by getting a new one. And, you should never be too embarrassed to ask for more information. It's your money and you have a right to understand what you're paying for. Let's review what an air filter does.
Air is the focus of this discussion. What is the air like outside right now? Can you see the smog? Is it full of pollen? How about dust? Anyone with hay fever can tell you that there's plenty in the air that you can't see. Well, it's the engine air filter's job to clean that air before it goes into your engine, to mix with the fuel and be burned. Without a filter, the inside of your engine would be extremely dirty from all the gunk that was burned in the cylinders.
In fact, for every gallon of gas you burn, your engine needs 12,000 gallons of air. That little filter does a very big job. It's no wonder that the air filter gets dirty and needs to be replaced. Think about a vacuum cleaner. When the bag gets full of dust and dirt, the vacuum doesn't clean as well. It can't move enough air to create good suction. A clogged engine air filter is the same way - the engine can't get enough air to burn the fuel efficiently. That means less power and wasted gas.
That's why your manufacturer has recommended that you change your filter at regular intervals. Of course the conditions you drive in will affect how quickly the filter gets dirty. If you drive where it's very dusty or where there's lots of pollen or pollution, you may need to change the filter sooner. The filter is easy to check visually, so your service technician can quickly make the call. He might recommend immediate replacement, or simply let you know that it is getting close and that you'll need to replace it soon - like at your next oil change.
Because a severely dirty air filter hurts your fuel economy, many people find that a new air filter pays for itself in gas savings before the next oil change. They also make premium air filters that have been proven to increase your horsepower and torque. If more power is important to you, a high performance air filter is some of the cheapest horsepower you can buy.
The better your car breathes, the better it runs - kind of like people. And don't worry - if you have a question or don't understand a recommendation just contact Oil Changers at 6433492567 or http://oilchangers.co.nz/locations

Transmission Care In Christchurch New Zealand
Posted July 30, 2010 12:17 PM
Call Oil Changers to make an appointment to check your transmission in Christchurch. 375 Main South Rd Christchurch, New Zealand 8441 6433492567
Do you have any plans around Christchurch New Zealand for the weekend? Maybe you and some friends and are taking the boat up to the lake. Maybe you'll be having a lot of fun water skiing and doing a little fishing.
You got the boat all ready. It's all gassed up. You packed lots of snacks and the cooler's stocked – ready to go.
How about your tow vehicle? It has plenty of gas and you've even vacuumed it out, but is your auto maintenance up to date?
Stop and think. You'll have some heavy traffic on your way out of town. Hilly terrain as you get to the lake. Some dirt roads – and it may be hot weather. And all the time you're going to be towing around several thousand extra pounds.
That all adds up a lot of severe strain on your engine, brakes and transmission. Your transmission's going to be working overtime, spending more time in lower gears. The internal transmission temperature is going to be much higher than normal. What's a fun little blast to the lake for you is really severe duty for your transmission.
It's important that you have enough transmission fluid. If you're running low, the transmission will run to hot and won't have the protection it needs to cope with the added stress of towing.
And if it's time for a transmission service, you really should have it done at Oil Changers before your trip. Transmission fluid breaks down and gets dirty over time. Whether you have an automatic or manual transmission, you need to have it serviced on schedule to make sure it runs efficiently.
Automatic transmissions contain a maze of passages that the fluid has to pass through to keep it shifting smoothly. If you neglect transmission service, the passages can get clogged up and you start to have problems. Neglect your transmission for too long, and it can fail. Believe us – you don't want to pay for a major transmission repair.
You know, most of us in Christchurch New Zealand do a lot of our driving under severe conditions. Towing or hauling a big load is obvious, but there are lots of other things that constitute severe driving conditions. Things like short trips or driving in very hot or very cold weather. Also, dusty roads, city driving around Christchurch, and basically any driving that's not at highway speeds or under ideal conditions is severe driving. We all need to think about whether or not we need to follow the severe service schedule.
So, consider going in for a full service oil change before you leave for the lake to make sure everything has been looked at. Ask for a trip inspection while you're at it. Your Christchurch New Zealand service technician at Oil Changers can check your belts and hoses and let you know if your brakes are in good shape.
Don't forget the sunscreen. And to thank your Christchurch service technician, how about bringing him back a nice trout?

Check Engine Light
Posted June 24, 2010 10:15 AM
Did you know that today's cars carry more computer power than the Apollo 121 Lunar Module that landed on the moon in 1969? New cars have as many as 12 networked computers and over five miles (eight kilometers) of wiring. In fact, for the last decade or so, computers have been controlling about 85% of your vehicle's functions.
Cars have sensors for manifold air temperature, coolant temperature, manifold air pressure, airflow, throttle position, vehicle speed and oxygen content. All of this electronic wizardry is pretty complicated. So how do you know when there is a problem?
It's simple - the Check Engine light comes on. The computer monitors all the sensors and uses that information to decide what to adjust such as the fuel mix, spark timing and idle speed. In addition, the computer monitors its own circuits. When it finds a fault, it turns on the Check Engine light and stores a trouble code in the computer.
It can be pretty disturbing when the Check Engine light comes on. We wonder just how urgent it is. Generally speaking, it is not critical like a temperature or oil pressure light. When you get one of those it means STOP NOW! When the Check Engine light shows up, you should get to your Christchurch automotive service center to find out what the matter is as soon as possible.
Since 1996, there has been a strong emissions control component to the Check Engine diagnostic. But if your Check Engine light flashes on and off, you know that it is more urgent and you need to get it checked immediately to prevent damage. You should slow down and avoid towing or heavy loads until you can get it checked out.
The automotive technicians at Oil Changers have special diagnostic equipment that will retrieve the trouble code from the computer and help determine what is wrong. From there, they can fix it and get you back on the road.

Recommended Service Intervals
Posted May 28, 2010 3:43 PM
Everyone in Christchurch knows we're supposed to go to the dentist twice a year. We get our teeth cleaned and have a thorough dental inspection. Once a year, we get x-rays to look for problems that can’t be seen with the naked eye. When the dentist is done, he tells us what he’s found – “Everything’s fine, see you in six months.” Or “You’ve got a small cavity starting, let’s schedule an appointment to take care of it.” By the time you leave, you have a plan for addressing any necessary repairs.
This system works so much better than waiting for a painful problem before going into the dentist. Small problems are fixed before they turn into big problems. And you avoid those huge bills.
If we buy into this way of handling our dental care, why do we resist so much when facing the same system for our car care?
Following the manufacturer’s recommended intervals can be confusing. First there are recommendations for so many things: oil changes, transmission, coolant, air conditioning, power steering, brakes, fuel system, filters, belts, hoses, alignment, rotation, balancing ...you get the point.
Every item has a recommended interval and it’s hard to keep it all straight – even if you’re part of the one percent of the population that reads your owners’ manual.
And if you have more than one Cars, the complexity is multiplied. You’d need a computer to keep track of everything. We’ll, that’s how Oil Changers does it. We subscribe to automotive databases that have your vehicle’s recommended intervals. You may have wondered how we know what else to recommend when you bring your car in for an oil change at our Christchurch location – it’s all in the computer.
Well, it’s not all in the computer. There are other variables that can’t be accounted for in the schedule. Things like the weather conditions, altitude, and driving conditions in the Christchurch area to be taken into account. Talk about these things with your Christchurch service advisor at Oil Changers and you may decide that the severe service schedule in your owner’s manual is more appropriate.
Since anything that’s not highway driving in moderate weather is considered severe, most of us in Christchurch do at least some of that and it should be taken into consideration.
Let’s take your basic oil change as an example – what issues are involved? The oil you put in your car is a blend of base oil and special additives. There are detergents to clean the inside of your engine and corrosion inhibitors. A good quality motor oil will not only lubricate your engine, it will help it stay clean inside and run cooler.
Now, these additives deplete with use and time. That’s why most maintenance recommendations include both a time and mileage element – like three months or 3,000 miles, whichever comes first.
It’s easy to think, “Gee, I’ve only driven 2,000 miles in the last three months. I can wait on that oil change.” But you need to remember that the inside of your engine is a harsh environment. The oil is contaminated with combustion by-products that start degrading its effectiveness even when it’s just sitting there.
A lot of people in Christchurch don’t realize the harm that can be done by just skipping a single oil change. There are a lot of metal parts moving around in your engine. Small bits of metal wear off and are floating around in your oil. They can be carried to more delicate areas of the engine where they cause damage. Your oil filter is designed to trap metal particles and other dirt, but if it’s clogged up because you haven’t changed it, it can’t trap any more.
Oil sludge is another problem. Sludge is oil that has turned to a gunky jelly – think Vaseline. Obviously, sludge doesn’t lubricate. It can also clog small oil passages so that all the parts don’t get properly protected by the oil. That’ll lead to premature wear.
If you’ve missed some oil changes, don’t despair. Just talk with your Oil Changers service advisor. Fess up – you’ll feel better. And he can help you get back on track. Following recommended intervals is the key to keeping your car on the road and avoiding major repairs.

Service to Improve Fuel Economy
Posted May 12, 2010 10:29 AM
The price of gas has got everyone talking. It seems that people who need a bigger vehicle to carry family and gear, or provide four wheel drive, are especially hit hard. That is why we thought it would be good to review some things that anyone can do to improve fuel economy.
First let's start with how we drive. People may not realize that they can really save on gas by just changing a few driving habits. One of the biggest is jackrabbit starts - you know, flooring the gas as soon as the light turns green. That really wastes a lot of fuel. Building up your speed at a slower pace uses less fuel and is easier on your engine and drive train. And don't drive with one foot on the brake. That's also a drag on fuel economy, and it wears out your brakes faster too.
Another thing is to drive slower - but only when it's safe. Sometimes on the highway we drive an extra five ... ten . . . twenty ... over the speed limit. We do it to save time, but it only saves a few minutes out of maybe an hour long drive, and we may use 10 to 15 % more gas. Just leave a little bit earlier, save some money and arrive more relaxed.
You can also try and group all of your errands for the day into just one trip, rather than several. If you can put off a trip today that can be combined with one tomorrow - you can save some time and money.
Using your cruise control can save money too. Driving at a constant speed really improves fuel economy. Be sure to only use your cruise control under safe conditions - you can look in your owner's manual for some good tips on using your cruise control.
Did you know that reducing the weight in your vehicle saves gas? Clean out the trunk or back seat from time to time so that you are not paying to carry around a lot of stuff you do not need in the car. If you live where there is snow and ice, clear it off your car. They add weight and mess with aerodynamics too.
Another tip is to avoid long idle times, which includes warming it up when you start. Modern engines do not require a long warm up to get going - just take it easy for a couple of miles.
Be sure to get a new gas cap if yours leaks or is worn.
Now, let's start talking mechanical. Bottom line - the better you maintain your vehicle, the less fuel you will use. It all adds up in a big way. For example, replacing your dirty engine air filter will pay for itself in fuel savings before your next oil change - and will keep saving you money after that.
A clean, well-maintained fuel system really pays big dividends. A clogged fuel filter wastes gas. So does a dirty fuel system, grimy fuel injectors and plugged up PCV valves. A fuel system service decreases the gas you use, and increases the power - so you can't go wrong with that.
Some of us ignore our Check Engine light. But fixing the problem that caused the light to come on will usually save some fuel as well. It may be a bad oxygen sensor that can really rob your fuel economy.
And, it may be time for a tune-up. Tune-ups should improve your fuel economy. Don't overlook the routine maintenance items, like scheduled oil changes, transmission and cooling system service. Dirty or low fluids actually use more fuel. Just look at your manufacturer's recommended service intervals in the owner's manual, or ask your Oil Changers service advisor for the schedule.
Don't forget your tires. Underinflated tires waste gas. And if your wheels are out of alignment you won't get the economy you need.
None of these things are very complicated or expensive to stay on top of. When you maintain your car properly, you save gas today, and prevent costly repairs tomorrow.

Keys to Long Lasting Vehicle
Posted March 18, 2010 2:40 PM
New cars cost so much these days. Add financing and insurance and, well a new vehicle may not seem so attractive. A lot of New Zealand people are hoping to make their cars last a lot longer.
The good news is that with the current state of automotive engineering and manufacture, there’s no reason a modern vehicle can’t be made to last for a 200,000 KM's or more.
There is an old saying that says, 'a stitch in time saves nine' and that is really true when it comes to taking care of your car. A great example is coolant service.
Over time, coolant becomes corrosive and actually starts to damage your radiator and other parts. That’s why you need to have your cooling system serviced on a regular schedule.
The same is true for your power steering system, brake fluid, air conditioning system, differential and transmission. And your oil changes should be done right on schedule to avoid the build up of harmful oil sludge.
Don't let your brake pads go too long before they are worn to the point that they cause damage to rotors. Preventive maintenance is a great way to keep your operating costs down.
Now this is a lot to remember. Oil Changers can keep on top of this stuff. We can tell you what your manufacturer recommends and help you with a plan to take care of it.
Bottom line – take care of this stuff on schedule and you will reduce operating costs, prevent costly damage and maintain your warranty coverage. Call Oil Changers today for an appointment; you can reach us at 6433492567.
Take good care of your car, and it’ll take good care of you.

Differential Service: What You Need To Know
Posted March 10, 2010 11:34 AM
Don’t be embarrassed if you don’t know what a differential is; you will in a moment. That fact is that if you drive a car, you have a differential. Whether your vehicle is front-wheel drive, rear-wheel drive or four-wheel drive, you have a differential. You might even have two or three.
As you might guess from the name, a differential’s job is to compensate for differences. Specifically the differences in wheel speed when turning. For instance, imagine taking a corner. Your inside wheel has a shorter distance to travel than the outside wheel as you go around the corner. That means that your outside wheel has to turn faster to keep pace with the inside wheel.
The differential allows the wheels to turn at different speeds while still providing power. Without a differential, our tires would scrub and hop along the pavement during turns.
You’ve probably noticed the big bugle in the middle of the rear axle when you’re behind a truck. That’s the differential. Rear-wheel drive vehicles have a differential in back. Most four-wheel drive trucks and SUVs will also have a similar differential on the front axle.
Front-wheel drive vehicles’ differential is called a transaxle because it combines the differential and transmission in one unit. An all-wheel drive vehicle will have a differential or transfer case that adjusts for speed differences between the front and rear drive wheels.
It can seem a little complicated. But you can see that all of the engine’s power is routed through your differentials. They’re strong enough to handle the work, but they need to be properly lubricated in order to stay strong. So from time to time, you need to have your differential serviced. Oil Changers can service your differential. The used fluid is drained and replaced with clean fluid. Some differentials also require special additives to be installed, and at Oil Changers we can help you with that, too.
The rule of thumb for the time and mileage interval for servicing your differential can vary greatly by vehicle. A front-wheel drive vehicle’s transaxle will need servicing more frequently than the rear differential on a pick-up truck, so check with your service advisor or your owner’s manual for recommendations.
How and where you drive will have an impact as well. If you drive on dirt roads or through streams or 4wding, you’ll need to service the differential at Oil Changers much sooner than if you always stay on the highway.

Vehicle Warranties In USA
Posted February 21, 2010 8:47 PM
PLEASE NOTE: THIS IS USA LAWS : If you own a vehicle with a warranty, beware! Many dealers and manufacturers suggest that you need to get your maintenance services at a dealership in order to keep your warranty. That simply isn't true! You can have your vehicle serviced at your trusted, local service center without affecting your warranty. A federal law, called the Magnuson-Moss Warranty Act, prohibits a manufacturer from voiding your warranty just because you got parts or services from a non-dealer. In fact, a manufacturer can't require you to use their brand of oil filters, lubricant, or any other part in order to maintain your warranty protection. This protection is true for aftermarket extended warranties purchased on new or used vehicles. This protection also applies to leased vehicles. There are similar laws in Canada and around the world as well.
If a manufacturer can prove that the replacement parts or service lead to a vehicle failure, they can void a portion of the warranty. Of course, Oil Changers uses quality parts and fluids that meet or exceed manufacturers' specifications. (See http://oilchangers.co.nz/locations.) A lot of people do not know that service centers subscribe to data services that tell them exactly which parts and fluids meet manufacturers' specifications. These services are updated constantly so that your automotive service center always knows what you need for your car. You can be assured that your vehicle will receive high quality replacement parts that'll keep you safely on the road.
Proper maintenance is so important to safety. It can also prevent costly repairs and save you money over the long haul. Just because you don't have to go to a dealer to get your maintenance service performed doesn't mean that you don't need to have it done at all. In fact, some protections from your warranty require that scheduled maintenance be performed. If you miss having important work done, you may lose some warranty coverage. Refer to your owners' manual and vehicle warranty for more details. And keep good records of the work you've had done.
The protection you receive under the Magnuson-Moss Warranty Act can save you hundreds of dollars each year. The average hourly labor rate for service is nearly twenty percent lower at independent service centers such as Oil Changers.
* Oil Changes only uses products / parts that meet or exceed original equipment manufacturers (OEM) specifications. All our products are backed with filter and oil manufacturer's warranties. We are not an authorised agent of any vehicle manufacturer. In some cases a new vehicle warranty may require that the vehicle is serviced at a particular dealership in order not to void the factory warranty.
Please ask a store manager if you have any questions in relation to your warranty

Radiator Service
Posted February 21, 2010 8:44 PM
The coolant system is a vital part of your vehicle. It is also the second most common cause for vehicle failures. Even though coolant system failure is fairly common, it is easy to prevent.
The most recognizable part of the coolant system is the radiator. It is connected to the engine with hoses and is filled with coolant. The coolant draws heat off the engine and then goes into the radiator. Air passes through cooling fins to reduce the temperature of the coolant and then it's back to the engine again.
There are several ways for the cooling system to fail. Most common is with the coolant itself. Coolant is a mixture of water and antifreeze. The proper mixture keeps the coolant from either boiling away or freezing. Both of which can result in massive engine damage.
Another very important coolant issue that is often overlooked is the age of the coolant itself. antifreeze has additives that protect the coolant system from corrosion. As these additives are depleted over time, they can't protect the radiator and other parts from rust, scaling and corrosion. Old coolant may still keep your engine cool, but it won't protect it from corrosion.
If you see a warning message to check the coolant or if the temperature gauge is in the hot zone your cooling system needs to be checked. It's OK to add water or antifreeze yourself. But you need to be cautious. Remember four things.
First, you never want to open the radiator pressure cap. You could be severely burned.
Second, try to get to a service center such as Oil Changers immediately if your coolant is low. If that is not possible, follow the directions in your owners manual - it will direct you to only make additions to the coolant overflow bottle.
Third, remember that you need a proper mixture of water and antifreeze. If you make an emergency addition to your cooling system, follow-up with your service center where they can make necessary corrections.
Fourth, not all cars use the same type of antifreeze. You need to check your owners manual to make sure you use the right kind. Mixing antifreeze types or using the wrong kind of antifreeze may void the manufacturers warranty on your cooling system. Again, another reason to rely on your Christchurch service center to do things right.
Remember, Oil Changers has the equipment to change your coolant quickly and inexpensively.
