Majority of Timing Belt Failures Caused by Faulty Tensioner Components
Majority of Timing Belt Failures Caused by Faulty Tensioner Components
Did you know that a majority of OHC timing belt failures are actually caused by faulty belt tensioners and pulleys? It's true. Timing belts don't last forever and neither do the tensioner components that keep the belt tight. That's why you should always replace the tensioner components when changing a timing belt. Reusing old tensioner components increases the risk of premature belt failure and expensive comebacks.

But a belt change alone may not be enough because the majority of belt failures are actually caused by faulty belt tensioners and pulleys. Consequently, the new timing belt you've just installed may fail after a few thousand miles if the tensioner components are worn or loose. This one page flyer explains why.
