To Fix or Not To Fix (Tire Repair)

You know that sinking feeling when you realize one of your tires has a problem.  It may be making an odd noise or behaving oddly when you're driving.  You may hit a pothole or curb and one suddenly goes flat.  Or you may head back to your vehicle and discover it has one tire deflated without a clue of what must have happened to it.

With a lot of different tires hitting the streets these days, the issue of whether to have a tire repaired or replaced can be tricky, and we strongly recommend you have a trained technician help you make that decision. 

One of the most common causes of flat tires is picking up a screw or nail in the tread area.  Many of those can be patched and plugged if the puncture isn't more than ¼ inch/6 mm in diameter. Most tires can handle two of this type of repair, but any more and you should buy a new tire. 

If there's a puncture or bulge in the sidewall or shoulder, the rule of thumb is it's not repairable.  The sidewall doesn't have the reinforcements that the tread area does.  In fact, any puncture that's more than a ½ inch/12 mm away from the edge of the tread should not be fixed. 

Many newer vehicles have no spare tires (to save weight and fuel) and instead have a type of tire called "run-flat."  Sometimes, the only way you know they're deflated is when the tire pressure monitor alerts the driver.  Driving on them more than 50 miles/80km can render them un-repairable.  They may be fixable if you pulled off to the side of the road before driving on them too long. Our technicians can evaluate whether they can be driven further or should be replaced.

Other vehicles with no spare include a can of tire sealant and a compressor.  If you use it, tire experts say to have the tire professionally repaired as soon as possible.

If you have had a flat tire, try not to drive on it unless it's necessary to get your vehicle away from a dangerous situation.  Our technicians can evaluate any tire you may be having problems with and recommend whether repair or replacement is the best option. Your safety is riding on your tires.

I'm Cool With That (AC Exchange)

On a hot day, you want your vehicle's air conditioning to work.  When the air blowing out of your vents isn't cold, it's easy to think, "I'll just take it by the shop and have them top off my refrigerant." But while some people think air conditioning is that simple, it's actually not.

If your refrigerant is low, something has to have happened for it to be depleted.  Perhaps there's a leak in the system.  Or some hoses or clamps have failed.  If the system isn't evaluated by someone who knows air conditioning, it's possible that adding refrigerant will just be a band-aid solution.

It's also possible that contaminants have gotten into the refrigerant, such as carbon dioxide, nitrogen, argon, or air.  Some of those gases do not condense like refrigerant does which can increase the pressure inside the system and strain the lines and other components. At that point, the best course of action may be to have the old refrigerant (with its contaminants) bled from the system and have your AC recharged with new refrigerant.

Bring it to us, and we can inspect and test the system and all its components.  That will include a pressure test for leaks.  Most vehicle manufacturers don't have a service schedule for air conditioning systems, so one way to know when you should have it looked at is when it's not behaving the way it used to.  For example, it may not get cold as fast as it did before or even at all.

So, when hot air is exiting your vents when you want it to be cold, schedule an appointment and have a trained technician take care of it.  Are you cool with that?

More than Pads and Rotors (Brake Caliper Replacement)

You might be familiar with brake pads and rotors, two components of your vehicle's brakes that have to be regularly serviced.  Here's another important component of your brakes: the calipers.

Calipers are used in disc brakes, the type of brakes now found in most recently manufactured vehicles.  A caliper is the part of the brakes that squeezes the brake pads against the discs, or rotors, which turn with your wheels. 

There are different kinds of calipers, but the basic principle is the same.  You press down the pedal, brake fluid activates a piston or pistons that squeeze the brake pads against the disc and the friction slows down your vehicle.

While modern vehicles have a warning system to let you know it's time to get your brakes checked, your brake light usually goes on when your fluid level is low or your fluid pressure is low.  But you may have to look out for signals your calipers are the problem. 

If your vehicle pulls to one side when you brake, that could be a sign that one caliper isn't working right.  If you smell a burning odor coming from a wheel after a trip, there might be too much pressure from a caliper.  Grinding or squealing when you brake is another signal that it may be time to bring in your vehicle so we can check your brakes.

One way to minimize brake issues is regular inspection.  Have them periodically looked at when you bring in your vehicle for an oil change.  The good news is brake issues are more likely to be caused by pads or rotors wearing out.  Calipers last a lot longer, but even they will need replacing every so often.

Rotation Explanation (Tire Rotation Patterns)

You may notice that when you get your vehicle's oil changed, your service adviser may recommend that you have your tires rotated at the same time.  The reasons are simple.  That will allow your tires to wear more evenly and reduce the noise your tires make as you drive down the road.

There are different ways of rotating tires. If your vehicle has non-directional tires and the same size wheels at each corner, here are the different rotation patterns.

For all-wheel drive and rear-wheel drive vehicles, one is called the rearward cross pattern.  The rear tires are moved to the front and stay on the same side of the vehicle, and the front tires are moved to the rear on the side opposite of where they were on the front. 

For all-wheel and four-wheel drive vehicles, use the X pattern.  The rear tires are moved to the front on the opposite side of the vehicle, and the fronts are moved to the rear on the opposite side of where they were on the front.

For front-wheel drive, there's the forward cross.  The front tires are moved to the rear wheels on the same side of the vehicle as they were on the front and the rear tires are moved to the opposite side of the vehicle than they were on the rear. 

If you have directional tires (they only can be mounted in one direction) and the same size directional wheels, the rear tires are moved to the front on the same side of the vehicle where they were, and the front tires are moved to the rear on the same side they were on the front.   And if you have tires with different sizes of non-directional tires and wheels on the front and rear, rotation will be from one side of the vehicle to the other. 

If you have a spare, it's put into the rotation using a forward cross or rearward cross. 

Yep, that's a lot to keep straight.  So, we suggest letting your service advisor recommend the right rotation pattern for you at the interval your vehicle's manufacturer specifies.

Not-So-Smooth Operator (Transmission Signs of Trouble)

You are heading down a flat, newly paved street when all of a sudden you feel it.  Your vehicle jumps a little bit when you're accelerating and changing gears.  You know it's not the surface of the road because it's smooth as silk.  So what did you just feel?

That kind of jumping—or grinding or slipping—during gear changes could be a sign of trouble in your automatic transmission.  And it's important to get it checked out fairly soon because some transmission problems that aren't fixed early can lead to more involved and expensive repairs.

By far most vehicles on the road in North America have automatic transmissions, and they are workhorses.  Unlike early cars with balky, hard-to-shift manual transmissions, the latest automatics allow you to drive without having to even think about gear changes.  But you should know about a few signs of trouble to look for if they ever start showing up.

  • When you first get going and shift your vehicle from Park into Drive, do you feel a slight pause?
  • How about when you shift into Reverse?  Is there a little lag?
  • Does your vehicle sometimes shake when you're traveling down the road?
  • Do you smell something burning in your engine compartment?
  • Do you hear a clunk when your vehicle shifts?
  • Do you have spots of a reddish or brown, oily fluid in the driveway under your vehicle?

If you do, these are worth getting checked out at our service center.  When automatic transmissions start to show signs of wear and age, it can be because of a number of reasons.  They can be caused by your transmission fluid getting old and contaminated, or its level may be low.  The gears can be worn.  You may have a leak somewhere in your transmission.  Or transmission problems might be caused by a computer problem.

Transmission issues aren't always expensive to repair.  Sometimes there may be a leak in a hose or gasket.  Or a computer needs to be reset.  Other issues may be much more involved.  This is why it's important to get your vehicle checked out when you do notice something doesn't feel, look, shift or smell quite right.  Everyone wants their automatic transmission to be a smooth operator.

A Clean Sweep (Fuel Injector Cleaning)

Your vehicle gets its power from burning fuel, usually gasoline, and it counts on something called fuel injectors to send gas to the engine in a spray that is easy to ignite.  It’s a precise operation, and when it’s working well, you have plenty of power and an efficient engine.

But after time, contaminants in the fuel system may prevent the injectors from spraying like they’re supposed to.  They can also shoot contaminants into the engine. 

One sign that could point to dirty fuel injectors is a misfiring engine. Misfires can be caused by several things, so it’s a good idea to bring your vehicle to us so we can trace the cause. Another sign is that your fuel economy has gone downhill or your engine doesn’t have the “pep” it used to.

If we discover that your injectors are clogged or not working the way they should, we can clean them to get rid of those contaminants to restore your engine to its top performance.  When you bring your vehicle to us, we will connect the flushing equipment, flush out the injectors and reassemble the system.

A good time to have fuel injectors inspected is when you bring your vehicle in for routine maintenance.  An oil change is an ideal time to have a technician take a close look at your entire fuel delivery system. 

When you have your fuel injectors cleaned, you may see your mileage go up, your engine performance improve, and your exhaust emissions decrease.

Steering You Right (Power Steering Signs of Problems)

Nearly every modern vehicle on the road today has power steering, a wonderful invention that makes steering take far less effort than it did in the "good old days."  Today, we take our steering for granted: until something goes wrong, that is.

Most power steering these days is rack-and-pinion, the rack being a metal bar between the front wheels with notches in it and the pinion being a gear whose teeth fits into those notches.  Adding power assist makes it easy to turn. That assist comes in the form of hydraulic fluid that is pressurized by a pump powered by the engine, an electric motor that adds a power assist or a system that uses both an electric motor and hydraulic fluid.

Your vehicle usually gives you a heads up that something is going wrong with its steering. Here are a few signs to look for:

  • A humming, whirring, rubbing or grinding sound coming from you engine compartment when you turn.
  • Signs of hydraulic fluid leaking, such as wet spots under your vehicle.
  • The smell of burning oil while you're driving.
  • Steering wheel hard to turn or vibrating.

If you notice any of these signs, it's a good idea to have a trained technician check them out.  They may be signs of:

  • Power steering pump going bad
  • Steering rack or gear seals wearing out, causing them to lose hydraulic fluid
  • Broken fluid hose
  • Defective power steering cooler
  • Loss of pressure in the power steering gearbox
  • Worn out steering pump belt
  • Failing electric power steering motor

It's important to have these checked out sooner rather than later. You need to be able to steer properly in order to drive safely. Plus, some of these problems can cause more serious—and expensive—damage if they're not fixed.  Power steering is a wonderful feature of your vehicle.  Keep it well maintained and it will steer you right.

Go With the Flow (MAF Sensor Replacement)

This MAF sensor is an important part of your vehicle.  What it does is calculate the amount of air going into your engine.  As you may know, air is taken into your engine where it's mixed with fuel.  Then the spark plugs fire, the explosive fuel/air mixture detonates, and these sequential explosions provide the power to get your vehicle moving down the road. 

It makes sense that if the MAF sensor isn't sending the engine's computers the correct information about the amount of air entering the engine, the fuel/air mixture won't be right. It will be either too rich (too much gasoline relative to the amount of air) or too lean (not enough gasoline relative to the amount of air).

In this driver's case, the MAF sensor was damaged and needed to be replaced.  Another thing that may cause the MAF to give an incorrect reading is if its wires are dirty or faulty.  So, replacing or cleaning the wires important as well.

Other symptoms that your MAF sensor is bad? If your engine hesitates when you step on the gas, stalls, or your vehicle is jerky when you accelerate. 

A malfunctioning MAF sensor is not just bad for performance.  Driving with your vehicle in that condition can cause more damage to your engine.  When you bring your vehicle in for us to check, a technician will thoroughly examine your engine to make sure all issues are taken care of.

Breathe Easier (Cabin Air Filter)

When you get in your vehicle, how does it smell? If it's not so nice, it may be time to have your cabin air filter changed.

It's not the same one that filters out the air used in the engine.  The cabin air filter screens out dust and other particulates from the outside air so when it enters the cabin, you don't have to breathe them in when you're driving.  Maybe your commute finds you traveling along dusty rural roads, or maybe you pass by some city factories that have smokestacks spewing out smoky exhausts.  Or in spring, maybe you notice your allergies acting up because of the pollen in the air.  The cabin air filter will remove a lot of those things.

The more it filters out, the more those small particles add up.  That reduces how much airflow the heating/air conditioning system can handle, and you may notice not as much air is coming through your vehicle's vents.  That can also be a sign you need your air filter replaced.

Our technicians will remove and inspect the air filter; it's usually located around the glove compartment, under the dash or sometimes in the engine compartment. If you wish, your service advisor can show you what condition yours is in; if it needs replacing, you'll be able to see the dirt, bugs, leaves and other crud that accumulates after several months of driving. 

Each vehicle's manufacturer recommends an interval after which your cabin air filter should be replaced. Depending on how much and where you drive, you might find yourself needing a replacement more or less often than the manual suggests.

Just like you clean your furnace filters periodically, it's wise to do the same with your vehicle.  After you do, you'll find you might just breathe easier!

Giving CV Joints the Boot! (CV Joint and Boot Replacement)

Ever wonder how your vehicle’s transmission is connected to your wheels? After all, when you hit a pothole or some other uneven part of a road’s surface, there has to be something that can maintain the connection between the transmission and the wheel yet keep everything moving at the same speed. 

That very cool device is called a CV joint, a kind of driveshaft running to each wheel.  The CV stands for constant velocity because it keeps the drive wheels moving at a constant speed (velocity).  They’re used mostly on front-wheel drive vehicles but also in rear-wheel and all-wheel drive vehicles.

The joints move up and down and adjust to bumpy surfaces.  Plus, they are covered in a rubber boot which protects them from road debris and also holds lubrication in.  There’s a CV joint and boot on the transmission side and one on the wheel side.  Unfortunately, the spot that usually fails first is that rubber protective cover (the boot).  After a lot of wear, tear, bumps, road hazards, heat, and you name it, the rubber rips and the lubrication leaks out.  At that point, it must be replaced. 

Here are signs to tell if your CV joint is bad.

  • Your vehicle is pulling to one side as a wheel loses power or you feel a vibration while driving.
  • You see grease on the inside or edge of your tires.  
  • Your front tires won’t point in the same direction.
  • You hear grinding or clicking when you turn.

Sometimes if a broken boot early is caught early, a technician can pack in new grease and replace just the boot.  But if the lubrication has leaked out and the joint is already wearing badly, the CV and boot both have to be replaced.  Give your vehicle the boot (as in a new boot) and CV joint, and you’ll be back on the road to your next destination.
