Timing Belt Tempe and Scottsdale AZ

Let’s address a very important maintenance item because letting this one slide can lead to very expensive engine damage!

The function of the timing belt isn’t as obvious to the general public as something like the brakes, steering, or electrical system. But the timing belt is a critical component of your engine, and letting maintenance on it slide can lead to extremely expensive damage to your engine.

Your timing belt choreographs the timing of the combustion process in your engine. Pistons travel up and down in the cylinder, and intake valves must open at just the right time to let in air and fuel. They also must close at the right time to allow the fuel to burn. The exhaust valves must open at the right time to release the exhaust.

How often does this occur? Oh, just thousands of times every minute. It’s an incredibly precise process, and it’s all run by the timing belt. It makes sure the valves open and close at exactly the right time. If the timing is off, your engine won’t run.

And that’s the best case scenario.

The worst case scenario is that a valve opens at the wrong time and collides with the piston. This causes bent valves and often, even more damage to the cylinder head. This damage can amount to several thousands of dollars in engine repair.

A timing belt, by its very nature, has a limited life. It wears out naturally over time, so it’s imperative that you replace a worn belt before it slips or breaks. Check your owner’s manual or with your service advisor at We-Fix-It Auto Repair in Tempe, Scottsdale, and Phoenix to find out when your timing belt needs to be replaced. If your odometer reads more than 60,000 miles and you’re still on your original timing belt, check with us right away to see if it’s time to be replaced.

In some engines, the water pump is driven by the timing belt (as opposed to the serpentine belt). If that’s the case, it’s a good idea to replace the water pump when you replace the timing belt (and vice versa), because since much of the same work has to be done for either part. This is also true for the timing belt tensioner — it should be inspected and, if necessary, replaced.

It’s true that replacing a timing belt is one of the more expensive routine maintenance items on your service schedule. However, ignoring the condition of your timing belt can lead to some of the most expensive repairs you’ll ever have.
