Timing Belt Replacement in Chicago

Today we want to talk about timing belts. Theyíre something that many Chicago drivers donít know much about and yet your vehicle wonít run if itís broken Ė and it could cause many thousands of dollars damage if it does break. A broken timing belt is usually a tale of woe. Even though timing belt replacement is scheduled in the ownerís manual, itís not the kind of thing that most Chicago car owners remember because itís not well understood.

Letís review what a timing belt does. As you know, the engineís power is generated in the cylinders. A piston rides up and down in the cylinder. During the first down stroke, an intake valve at the top of the cylinder opens and air and fuel is drawn into the cylinder. Then the piston returns to the top, compressing the fuel and air mix. At the top, the spark plug fires, igniting the fuel pushing the piston down in the power stroke. As the piston once again returns up in the final stroke of the cycle, an exhaust valve opens at the top of the cylinder and the exhaust is pushed out. The timing belt is what coordinates the opening and closing of the intake and exhaust valves. Itís called a timing belt because the valves have to open and close at just the right time.

Now, not all Old
Irving park and Jefferson park vehicles have timing belts. Some have timing chains. Like the name implies, they use a chain rather than a belt to perform the function. It used to be that most engines used timing chains, which are extremely durable. Manufacturers started using belts rather than chains to save money in the manufacturing process. So now we're left with a component that can break. They sort of shifted the problem to us. There are two broad categories of engine design: interference and non-interference. If the timing belt on a non-interference engine breaks, the engine simply stops running. That could be very dangerous depending on where you are at the time, but it causes no internal engine damage.

Interference engines, on the other hand, will get real messed up when the timing belt breaks, because the valves will actually fall down into the path of the pistons. Things get chewed up when that happens and itíll cost thousands to repair the engine.

So, what are the warning signs? Unfortunately, there really arenít any. There arenít tell-tale sounds. In some vehicles, a technician from Triangle Auto Service may be able to see part of the belt for a visual inspection, but many have a cover thatís in the way. The reality is that if the belt slips even one notch, it might as well be broken for all the damage itíll cause. Thereís no middle ground.

So how can we avoid these problems? Simply replace the timing belt when your ownerís manual calls for it. It can be 60,000 miles; it might be 90,000 or 100,000 miles. The point is, if you have 60,000 or more miles, ask your Triangle Auto Service service adviser right away if your manufacturer requires a timing belt replacement.

Sometimes you can go quite a while without a failure, but weíve seen them happen within a couple of oil changes of being due. Itís not worth the risk.

What does it cost to replace a timing belt in Jefferson park or Norwood park? Well, that really depends on what kind of car you have. I can tell you that itís usually not very easy to get to the timing belt Ė you often have to remove some accessories to get at it. It isnít a cheap procedure, but itís a fraction of what it could cost to repair the damage caused by a failure.

At Triangle Auto Service weíre all about trying to prevent costly repairs, keeping you and your passengers safe and increasing your driving enjoyment.   Triangle Auto Service 4060 N.
