Before You Buy that Used Vehicle (Having a Used Car Inspected Before Buying)

Let's face it.  New vehicles are expensive, so finding a good used one can save drivers a lot of money.  It's tempting to look through ads, find a private seller who has what you're looking for and pay a price you think is a great deal.  But when you go over to look at a used car, do you really know what to look for to uncover potential problems with it?

The answer is probably no.  Used cars can look great on the outside, maybe even have lustrous paint and a super clean interior. But is it possible that vehicle's been in an accident? Does it have electrical problems you can't detect easily? Is any fluid leaking that you don't know about?

Think about it.  You are about to spend thousands of dollars for a complex machine and you're considering judging its condition without much expertise.  That's why it makes sense to have a qualified technician inspect any used vehicle you're considering buying.

Many vehicle repair facilities will do it for around $100-$200.  They'll check to see what's working right and what's not working.  They'll check for leaks and how strong the battery is; they'll look for signs it's been in an accident or has been painted. They'll look in places you'd find inaccessible, and they'll take it for a test drive to see what noises, vibrations and smells might give clues to any major problems.  An inspection usually takes about an hour.

You should have an inspection done by a technician you know and trust.  They'll have your best interests in mind.  And the inspection should be done before you start negotiating a price with the seller.  It's money well spent to either give you peace of mind that you're getting a good vehicle or steer you away from a lemon. 

One sign a used vehicle isn't a good deal? If the buyer refuses to let you have it inspected.  That says just about everything that needs to be said.

(Timing Belt)

You may have heard about an important part of your vehicle's engine called a timing belt, and many know that if that belt breaks, it can cause some very serious engine problems.  

Not all vehicles have them, and the ones that do generally have smaller engines.  The timing belt keeps the engine synchronized so that every time a spark plug fires, the crankshaft, camshaft, pistons, and valves are all working together.  Timing belts will eventually have to be replaced, and most vehicle manufacturers recommend when that should be.  Typically, it's around every 60,000-100,000 miles, or 100,000-160,000 km. It's a good idea to stick to your vehicle's schedule or be alert for signs that the timing belt may be failing prematurely.

Some of those symptoms? Maybe your engine won't even turn over when you try firing it up. You might hear a ticking or banging sound under the hood.  Perhaps you spot an oil leak or notice the engine misfiring.  If any of those are happening to your vehicle, we strongly advise you to bring it in to us so we can have a technician see what's causing the issue. 

Again, if your timing belt breaks, it can cause serious, expensive engine damage to valves and pistons. It is far better to have the timing belt replaced before it breaks.

Replacing it is fairly involved, and other associated parts, such as the water pump, thermostat, tensioner, and idler pulleys may be replaced at the same time.  That way, your timing belt is more likely to last another 60,000-100,000 miles/100,000-160,000 km without any problems. 

Timing belts are being used in fewer vehicles, with more and more using timing chains since they last longer.  If you're wondering if your vehicle has one, contact our service adviser who can check. Maybe it's time to schedule a timing belt replacement to keep your vehicle's engine parts working in harmony as they should.

Command Performance (Engine Air Filter)

The internal combustion engine in your vehicle counts on two things that mix together to be burned in the engine for power: fuel and air.  Both are important, of course.  If you run out of fuel, your engine won’t run at all.  Since there’s plenty of air around, you won’t run out of air, but you could feel your vehicle’s performance suffer if the engine air filter starts to get clogged. 

It's important that the air that enters your engine be free of dirt, dust, and debris to prevent damage to internal components.  That’s where the engine air filter comes in.  It prevents those particles from entering the engine, an important job that most people just take for granted.

After a while, your air filter will get dirty, which results in less air reaching the engine.  Modern fuel injected engines can adjust the amount of gas to mix with the air that is getting in, so your fuel economy won’t change significantly.  What will change is how well the engine performs, its acceleration.  In one test, a US Department of Energy study showed that a dirty air filter reduced a vehicle’s get-up-and-go by as much as 11 percent.  

The company that made your vehicle includes guidelines in your owner’s manual on how frequently that filter should be changed, and doing so will maintain your engine’s performance. If you drive in dusty, dirty areas or those with a lot of industrial pollution, we recommend you replace the engine air filter more frequently than the manufacturer’s recommendations.  

When you bring your vehicle to us for regular maintenance, we will routinely check several components, including your engine air filter, and recommend a change when we see signs it’s needed. It’s good for your engine, and you’ll enjoy the performance you expect.

When Metal Meets Metal (Wheel Bearings)

What part of your vehicle has little metal balls inside that are lubricated and allow you to cruise on down the road?  They are wheel bearings, and automotive designers might argue they are human beings' second greatest invention of all time (the first is, of course, the wheel!).

You have a wheel bearing at each wheel.  They allow your wheels to turn freely, minimizing friction that would ordinarily slow you down when metal meets metal.  When one of your wheel bearings starts to go bad, it lets you know. A wheel bearing does its work quietly when it's in good health but starts getting noisy when it isn't.  People describe the noise differently.  Sometimes it sounds like road noise, a pulsating, rhythmic, sound.  That pulse speeds up when your vehicle speeds up. 

Here's what's happening when you hear that sound.  As mentioned, the bearing has these little metal balls inside a ring.  They have a lubricant inside to reduce friction between the balls; modern wheel bearings are sealed and they're intended to do their job without any maintenance. 

Wheel bearings take a beating; you hit some rough potholes or go over some uneven railroad tracks. Sometimes water can get into a bearing and reduce the ability of the lubricant to do its job.  Time starts to take its toll, too. When the lubricant isn't reducing friction like it should, the bearing can heat up. One of those little balls can start shedding pieces of metal and soon those shards start grinding up the other balls.  Friction takes over and soon your wheel isn't turning smoothly. That's what's causing the sound.  If a wheel bearing is not fixed, it could eventually seize up completely, and you can be stranded.

It's a lot easier if you heed the early warning signals, that pulsating noise.  Now, sometimes a similar noise can be caused by a bad tire, but in either case, it's important to have it checked out. Our Westmoreland Transmissions technicians will be able to tell you fairly quickly what the problem is and offer a solution.

Wheel bearings generally don't fail often and usually last from 85,000-100,000 miles/140,000km to 160,000km. But consider them a long-term maintenance item that, once fixed, will keep you heading smoothly to the next destination.

What is a TPS? (Throttle Position Sensor)

You know you have an accelerator pedal; step on it and your vehicle is supposed to go.  But did you know there is a part in your vehicle that keeps track of where the throttle is? It's called the Throttle Position Sensor, or TPS.

The TPS is a sensor that helps your vehicle figure out the right mix of air and fuel is reaching your engine.  It does that by keeping track of the throttle and sending that information to your vehicle's computer.  Other factors play a role in how well your engine is performing, including air temperature, how fast the engine is turning over and air flow. 

When the TPS isn't working right, you may find your vehicle won't accelerate or doesn't have the power you're expecting when you press on the accelerator.  In some cases, it may accelerate on its own.  Sometimes your vehicle won't go over a certain speed.  Your Check Engine light may go on.

Any of these symptoms should be checked out soon.  If your TPS stops working right, your vehicle may not be safe to drive.  Fortunately, most vehicles have a "limp home" mode that will allow you to get off a busy road to a safe spot. 

Your service advisor can let you know which TPS is the correct replacement for your vehicle.  Your shop may have to re-program the new TPS so it works correctly with other software in your vehicle.

It's a fact of life these days that computers control many of a vehicle's functions. The sensors that feed information to those computers help make your vehicle work the way it was engineered to and keep you motoring down the road safely and efficiently.
