Give it the Boot (Ball Joint Boot Replacement)

Your vehicle may be wearing boots right now and you might not even know it.  They're called ball joint boots.  They're actually protective, flexible things that protect parts of your suspension (called ball joints) from all the hazards the road can fling at them.  If one of those ball joint boots fails and you don't get it replaced, the ball joints themselves could wind up failing, a repair that can be even more expensive. 

Ball joint boots not only keep things like rocks, salt, water and dirt out of your ball joints, they also help the ball joints keep their lubrication inside and working properly.  To do that, the boots have to be made of a flexible material, sometimes rubber, sometimes a synthetic.  They do take a beating, exposed to temperature extremes and debris, and eventually they can tear or crack just because of their age.  Unless someone is keeping an eye on your ball joint boots, you may never know there's a problem.  That's why when you regularly take your vehicle in to a repair facility for other things like oil changes and routine maintenance, a technician will inspect the ball joint boots to make sure they're still in top shape.

If they're not, your service advisor will let you know. Take care of that soon and you may avoid having to replace the ball joints themselves or other suspension parts which may be much more expensive.  Often it's best to replace boots on both sides of the vehicle since they frequently wear at about the same rate. 

If you want to make a fashion statement, some ball joint boots come in various colors other than run-of-the-mill black.  And some aftermarket boots are made of a more durable material than the original equipment that came on your vehicle.  Some drivers get a real "kick" out of flashy ball joint boots!

A Stitch in Time at A.G. Automotive & Diagnosis

You probably have heard that expression, "A stitch in time saves nine." In other words, if you fix an issue at its early stages, it will prevent a much more difficult problem later. That's certainly the case with your vehicle, and here's a true story to demonstrate it.

A driver noticed his vehicle was due for an oil change, so he took it in to his service facility early in the morning so he could wait while the work was performed. The technician routinely checks the battery on vehicles just before extreme weather is approaching (cold or hot), so with winter coming up, he hooked up the load tester (it measures voltage while a load is put on the battery). It showed the battery wasn't holding a charge well.

The technician checked the manufacturing date on the battery, too (most batteries have a date stamped in code somewhere on them). The date showed it was five years old. While batteries can last more than five years, many technicians say you should expect to get anywhere from three to six years out of them, depending on what they go through.

So, this battery was getting a little long in the tooth, and it wasn't holding a charge particularly well. But how much current was it being sent by the vehicle's alternator? If it wasn't getting enough, that might be a factor. A test of the charging system showed the alternator was putting out the correct amount of power. The technician recommended replacing the battery, and the driver agreed.

That was the stitch in time. Had the technician not checked the battery, that driver likely would have been stranded the next time he tried to start his vehicle on a very cold day. What originally was supposed to be just an oil change led to a technician's sharp diagnosis and a little preventative maintenance for one fortunate driver. Sometimes timing is everything.

Out of Joint (CV Joint and Boot Replacement)

If you have a front-wheel-drive vehicle, it has components called CV joints which enable you to turn your wheels smoothly. The CV stands for “constant velocity.” In essence, it’s a set of gears that connect a shaft that allows power from the transmission to be sent to the wheels.  When you turn the wheels, no matter what angle, the input velocity rotation will be equal to the output. Thus, the name, CV (constant velocity) joint. Other vehicles with 4-wheel drive and all-wheel drive also use CV joints.  

If one of your CV joints isn’t working right, you may find your vehicle difficult to handle.  If one breaks, your vehicle may stop moving.  So, it’s important that CV joints be in top working condition.  The joints need a lot of lubrication, so they are surrounded by grease.  There’s a rubber enclosure around them called the boot which holds the grease in and protects CV joints from the elements. 
 
The biggest problems come when one of those rubber boots cracks.  Water and dirt can then get into the joint, causing it to wear down and lose all its vital lubrication.  It’s important to have your CV joints inspected regularly so a technician can spot cracks before the CV joints are ruined.  Sometimes just the boot can be replaced before any major damage is done.  But when the joint does go bad, it must be replaced.  

Signs your CV joint needs changing out? You might hear a clicking sound when you turn if the CV joint is worn out. You might notice some thick, black grease around your wheel or on the pavement where you park your vehicle.  You might also feel your vehicle vibrate when you’re going fast.

If you suspect you might have a bad CV joint, bring your vehicle in so a technician can determine what’s going on.  Keep your CV joints in good shape and reduce the risk of them seizing up at an inopportune time so you can avoid being stranded.

No Fueling Around (Fuel Filter Replacement)

A driver called in to the shop the other day saying his European sports sedan had an odd problem.  He was driving when his car started to slow down.  Applying more throttle didn't help.  He pulled over to the side of the road, shut the engine off and waited a few minutes before starting it up again.  It ran fine… for a couple of minutes.  Then the same thing happened.  He was able to finally get home by stopping and restarting, and he was calling to see if we could take a look at it. 

Turned out it was one of his car's fuel filters that choked up with debris so badly that enough fuel couldn't get through it.  When he stopped the car, enough fuel could flow through the unpressurized fuel line to supply enough fuel for a couple of minutes when he restarted his car. But then the pressure would cause things to clog again.  

There are other symptoms that point to a failing fuel filter. Perhaps your engine misfires, your vehicle is hard to start, or your fuel pump starts making odd noises. 
If you experience any of these signs, bring your vehicle in so we can have a technician check it out. 

Many vehicles have at least two fuel filters. One is a strainer that is part of the fuel pump in the fuel tank, and the other is in the main fuel line. Your vehicle's manufacturer recommends how often yours should be changed, but your driving habits and environment (such as dirty or dusty conditions) may mean yours will have to be replaced more often.  

The technician will also look to see if your vehicle might have another problem that's causing your fuel filter to fail more frequently than normal, such as corrosion in the fuel tank. 

Your engine needs fuel to run. Maintain the health of your fuel system and that will help keep you on the road to your destination.

Singing a Different Tune (Up) (Tune Ups)

Engines required a lot more maintenance in earlier times.  You'd have to have your spark plugs, wires, rotors, caps, distributor points, fuel and air filters changed periodically.  There were mechanical adjustments of a vehicle's timing, dwell, spark gap and idle mixture, too. Unless you like to tinker with old cars, a lot of those terms won't mean much to you. 

That service was called a "tune up" back then, and you can see why.  But now, computers have reduced the number of maintenance items, and a tune up is a whole lot different than it used to be.  In fact, in some vehicle service facilities, that term is also a thing of the past. 

A tune up of today would more accurately be called simply periodic maintenance. Now, most vehicles still have spark plugs and wires, fuel filters, air filters and PCV valves, and they should be inspected tested and/or replaced at regular intervals.  Your vehicle's manufacturer has made recommendations on how often that should be. But it depends on your driving habits. Do you regularly tow a trailer? Do you drive on dusty roads often? Are you driving mostly stop and go in the city?  Depending on your answers, to those maintenance intervals might have to be more frequent.

Your service advisor will likely remind you about those "must check" items such as spark plugs and wires, air filter and oxygen sensor.  And now that the old-fashioned tune ups don't require you to take your vehicle in for maintenance as often, you can get the same benefit from scheduled oil changes or tire rotations.  When your vehicle is in for those, a technician can keep an eye on your other systems (fuel, emissions, ignition) to make sure they are operating correctly.

One thing to remember.  When you take your vehicle in for regular service or a specific issue, don't ever hesitate to ask you service advisor to explain what's being done and why.  Hey, "In Sync" may have been a boy band of an earlier era, but it's always good for you and your service advisor to be "in sync" when it comes to what maintenance is good for your vehicle.

Why did my vehicle fail its emissions test?

We all want to breathe clean air and keep our planet green.  One of the ways to do that is by requiring all vehicles with internal combustion engines to pass an emissions test.  That’s because these vehicles can be big polluters.  

Everyone wants their car to pass the test so they can continue their day-to-day driving routine.  But then comes that one day when they tell you your vehicle has failed.  Why does that happen?

One of the most common reasons is that your gas cap is leaking or loose (or maybe you don’t even have one on your vehicle!).  The gas cap is supposed to seal in vapors, but sometimes its seals or gaskets dry out or crack. Replace it, and you’re good to go.

Another common reason your vehicle failed the test is that your catalytic converter isn’t doing its job. It is supposed to convert toxic gases from your engine into ones that don’t pollute the air.  There are many reasons the catalytic converter may not be working.  It may be physically damaged, or the steady flow of exhaust gases has fouled the converter. 

You may have a bad oxygen sensor. It’s supposed to measure how much oxygen is in your exhaust.  This can cause the air-fuel mixture to be too rich, resulting in too many hydrocarbons in the exhaust. Your ignition system may also have problems, such as worn-out spark plugs.  Dirty fuel injectors can contribute to excess emissions.

Believe it or not, a dirty engine air filter may be the culprit. If it hasn’t been replaced for a while, your vehicle may be emitting too many hydrocarbons -  something that will cause your vehicle to fail the emissions test.

You can usually avoid a failed emissions test by maintaining your vehicle regularly.  The best way to do that is by bringing it to our trained technicians, so your vehicle gets the service it needs, scheduled and non-scheduled.  Plus, you’ll be doing your part to keep our air clean.

A Bright Spark (Ignition Coil Replacement)

Ever wonder how your vehicle’s engine is able to take the 12-volts from its battery and ramp that up to as high as the tens of thousands of volts it takes to fire its spark plugs? The secret is something called an ignition coil.  Most newer vehicles have an ignition coil at each cylinder, but older ones have a coil that serves all of the spark plugs. 

There are telltale signs that you have an ignition coil problem.  As you might expect, one symptom is it’s hard to start your engine or it won’t start at all.  If your engine is misfiring or not running smoothly or you see the Check Engine light come on, those all could point to an ignition coil failure.

Several things can contribute to ignition coil trouble in addition to normal wear and tear. Moisture and dirt may have gotten inside the coil, plus the heat and vibration of your engine over time can contribute to them going bad.  Bad spark plugs or plug wires can also be a cause.  

While ignition coils can last 100,000 miles/160,000 km, depending on how you drive and in what conditions.  If you start noticing some of the signs and symptoms just described, it’s a good idea to schedule a visit to see us so a technician can diagnose what’s wrong. Driving too long with an engine misfiring can damage your catalytic converter, and that can be expensive to replace.

A technician will thoroughly check your ignition system and determine where the failure is.  If it’s only one coil that’s bad, it may be the only thing that will need replacing.  If your vehicle has a distributor, it may also need to be replaced.  Properly-working ignition coils will help your vehicle operate at its best and help prevent future engine damage.

QUIET TIME (Listening for Vehicle Problems)

Everybody's got friends like this.  You know, the kind who, the minute they get in their vehicle and turn the key, the sound system is deafening.  They just love to hear that music, sports, news… anything but the sound of the vehicle itself.

And maybe you're that person, too.  Here's something to consider: your sound system might be drowning out some valuable clues that could help you diagnose problems with your vehicle, problems that need to be dealt with. So, turn down the volume and listen for these things:

• A clicking sound when you're braking or turning—You could be missing some parts in your braking system, or it could be damaged. That sound could also signal that components are just plain worn out.
• Rattling under the hood—If it sounds like metal clanking against metal, you could have something serious going on, maybe an overheating engine or your timing needs adjusting. That knocking sound could also be as simple as you've been using lower octane gasoline than is recommended for your engine.  Time to get that checked out.
• A squealing or high-pitched sound coming from the engine compartment. Could be a belt is loose, wearing out, dried out or cracked. A pulley might be failing or a bearing might be on its last legs.  Better to have that fixed now than be stranded somewhere later.

Here’s our A.G. Automotive & Diagnosis suggestion - set a regular weekly alarm in your smartphone alerting you to listen to your vehicle once a week for five minutes.  Just five minutes without the music or the sports show or public radio… whatever your taste is. You can even use your smartphone to record any noise you might be hearing.  Between that and your description to your service advisor, a A.G. Automotive & Diagnosis technician should be able to diagnose the source of the noise and get your vehicle sounding healthy again. Do it before that noise turns into the sound of a serious problem. 

Who knew a little quiet time could be so useful?

Make your Service Visit at A.G. Automotive & Diagnosis a Good One

Most people don't love going to get their vehicle serviced, but it's one of those things you just have to do. So you might as well get the most of out of it. There are some steps you can take that will likely help you get the best results possible.

For one thing, it's important to describe your problem (or problems) to the service advisor accurately and clearly. If your vehicle is making a noise, for example, take time to really listen to it and think of the best way to describe it. Does it increase in speed when you go faster? If you feel a vibration somewhere, where in the vehicle does it seem to originate? Some service advisors recommend writing things down. That way the driver won't forget any important clues that could lead to a successful resolution of the problem.

Another thing is to make sure your vehicle is cleaned out and free of junk. That way the technician can access those nooks and crannies where some vital components may be. If your vehicle is full of strollers, boxes or your collection of fast food containers, it won't be easy for the technician to reach some of those parts. Oh, and if your vehicle is neat, it does send a signal that you really care about it.

Finally, stay out of the way of the technician. A recent survey of technicians reveals they work more efficiently and do a better job when they don't have someone hanging on their every move. Can you imagine how you'd feel if someone hovered over you all day while you were trying to get your work done?

Losing Your Cool (Why is My Air Conditioning System Not Working?)

When you turn on the air conditioning in your vehicle, you expect cool air to come out of the vents.  You depend on it, especially in hot weather, but it can also be important in humid weather when you need it to help defrost your windows and windshield.

The air conditioning system has a lot of parts to it.  It has fans and blowers to move the air through the vents into the cabin.  It has parts that take hot air and cool it off. An electrical problem can be as simple as a broken switch or a broken blower motor. The air may not be getting cool because a hose in the system is broken or the refrigerant has leaked out. 

Two major components are the compressor and the condenser.  The compressor pressurizes the refrigerant, one step in the air conditioning process.  The condenser takes that hot refrigerant and cools it down. It also reduces the pressure.

Because the climate control system in your vehicle is so complex, it’s best to leave the diagnosis to a trained, experienced technician.  You can help the technician zero in on the problem by noting what is happening and being able to show them where you notice the issues. Note what’s going on and write it down. 

When you bring your vehicle in to us to look at, a technician will inspect the system, conduct tests to make sure there’s enough refrigerant, and check to make sure there are no leaks anywhere.

Air conditioning is now included in most vehicles.  We all have grown used to being able to keep the cabin comfortable no matter what it’s like outside.  Let us make sure your system is working the way it was designed to.  That’s definitely the cool thing to do.
