One area of possible concern for car owners is the type of engine that they have. With a trusty Haynes or Chilton car maintenance and repair manual by your side, you can lift the hood and remove and replace the timing belt (and water pump) in no time. Weekend mechanics often feel comfortable enough to replace their car’s timing belt without the assistance of a garage. If the latter takes place, you could be faced with a significant car repair bill in addition to going through all the trouble of being without your car for several days. ![]() This is your decision as a water pump could last as long as your car or it could fail at some point in the future. Furthermore, many mechanics will also advise changing the water pump at the same time as the timing belt – even if it hasn’t failed – as most of the labor that’s related to replacing a water pump has already been done when changing the timing belt. Instead, changing it at prescribed intervals will reduce the chance that it will break before it can be replaced. Unfortunately, there is no iron-clad method to check that a timing belt has worn out. You will pay more for a complete timing system replacement and a water pump change out, but you will save on labor when your pump eventually does fail. Thus, a timing system replacement that includes the belt, an idler and a tensioner may be the best approach here.Īnd while you are at it, you may want to have the water pump replaced while your mechanic is working in the same area. If either part is worn or loose, it could cause your replacement timing belt to fail soon after it has been installed. When replacing a timing belt, your mechanic may recommend that you also replace the tensioners and idlers that hold the timing belt in place. Ultimately, you will want to schedule a timing belt replacement before your manufacturer says that it is due. Made of rubber with high-tensile fibers, a timing belt can wear down from use as well as from age. Mechanics may recommend that you change it once every four to six years, even if you have not reached the mileage threshold. You may have heard mileage numbers ranging from 60,000 to 100,000 miles. ![]() Your manufacturer plainly states in your owners manual the replacement intervals for a timing belt.

The timing belt enables two divergent components camshaft and crankshaft to do what they do together. The camshaft is tasked with opening and closing the engines valves to bring gas and air into the engine and out again. The crankshaft changes piston linear energy into rotational energy that is used to turn the wheels. Essentially, the timing belt keeps your engine in sync by providing timed motion between the camshaft and the crankshaft. Also known as a timing chain or cam belt, a timing belt is tasked with turning the engines camshaft.
