The timing belt is important because makes the internal components of the engine work together. I could get real technical and tell you how the timing belt keeps the flux capacitor inline with the rotary girder but I won't bore you with the details. Basically, what you need to know is the timing belt is a rubber belt that controls how the valves and pistons move inside of the motor. Because the belt is rubber, it is subject to shredding, breaking or slipping which can cause all kinds of horrible engine damage. Our recommendation is to replace the belt as maintenance at the recommended mileage by your manufacturer to prevent any engine problems. Also, on most vehicles the timing belt runs the water pump, other idler pulleys and a has its own belt tensioner.
We always recommend to replace all of the components when we install a timing belt. It makes sense. Not too long ago we had a vehicle in because the water pump was leaking and the customer just had her timing belt replaced at another shop only a few months prior. It was such a bummer because this problem could have been easily prevented had the water pump been replaced while they were installing the timing belt. Not every vehicle has a rubber timing belt, some vehicles use a chain and gears. Timing chains do not have to be replaced as maintenance. On most vehicles, unless there is an unusual internal engine problem it is very rare that a timing chain and gear set needs to be replaced. In summary, follow your maintenance schedule and replace your timing belt when required, it will save you lots of headaches in the long run. If you are unsure if your vehicle has a timing belt or when it should be replaced, give us a call. 563-388-9363 We will be glad to look up the information required by your manufacturer for you.
