Timing is Everything (Timing Belt)

Talk about exquisite choreography; it happens under the hood of your vehicle every time you take a drive.  Your engine’s many complex parts must work exactly together.  One key is a part called a timing belt, which enables the synchronizing of two of your engine’s components, the camshaft, and the crankshaft.  

The timing belt coordinates the valves in your engine to open and close at the appropriate time to get exhaust out of the engine’s cylinders. Timing belts may also power the water pump and the oil pump.  The belt is made of rubber.  Some engines use a timing chain (made of metal). 

Your vehicle’s manufacturer recommends an interval after which you should have your timing belt or chain replaced, and that service should be part of your vehicle’s regular maintenance.  It’s always better to replace it before it breaks rather than after.  After all, if your timing belt breaks while you’re driving down the road, it throws off the whole sync of engine parts and can cause major damage to the type of engines most commonly used in vehicles today.

It’s also important to remember that a timing belt is made of rubber, and rubber deteriorates with time, no matter how much use it gets. Have us look at your timing belt to see if it’s time to get it replaced.  

Here are some signs to look for that will let you know if your timing belt is failing. You might have trouble starting your vehicle, it may misfire or black smoke may come out the tailpipe. If you notice any of those symptoms, bring your vehicle in and have us take a look right away.  When it comes to your engine, timing is everything.

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.

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.

Flat Tire? Three?s the Charm (Tire Repair)

For most drivers, at some point you’re going to have a flat tire. Depending on how it was damaged, it may have to be replaced.  But sometimes, a repair will do the trick, as long as the puncture isn’t on the sidewall and the hole is smaller than ¼ inch/6.35mm in diameter. Here are the three common ways your tire can be fixed.

One way is to put a plug in the hole.  Since most tires are damaged by running over sharp objects such as screws and nails, the small hole from which the air is escaping is on the part of the tire that touches the road. If it’s in the sidewall, it most likely can’t be fixed.  

In the plug method, a technician inserets a rubber plug.  It is covered with some sticky, gluey stuff, and is pushed into the hole from the outside. That plugs the hole and stays in place, thanks to the glue. Friction from driving heats it up and seals the deal.  

Another method is to patch the hole.  For this, your tire has to first be taken off the vehicle, then off the rim so the technician can get access to the inside. There, they’ll clean the inside surface around the hole and apply a rubber patch with an adhesive on it. This type of patch works well, and because of the extra steps and complexity, costs more than having your tire plugged.  

There’s also a combination of those methods just described, the plug-patch.  It is, in essence, a type of patch with glue on it that has a plug sticking out of it.  The plug is inserted into the tire from the inside and pulled through the hole from the outside, drawing the attached patch tight against the tire’s inside surface. The last two methods can’t be used if the hole is near another repair or the sidewall.    

The good news is if it’s fixed properly, your repaired tire should give you good service.
