Timing Belt Tensioner Video

The timing belt tensioner applies pressure to the timing belt, helping keep it tight and operating smoothly. When issues develop, the tensioner is often the cause rather than the timing belt itself.


To help prevent failure, the timing belt, tensioner, and related components like idler pulleys are typically replaced at recommended intervals. If you’re unsure what that interval is for your car, truck, or SUV, the service advisors at Blackwell Automotive in Phoenix, AZ can help.


If a timing belt tensioner fails, it can cause the timing belt to loosen, slip, or break. This can disrupt the precise timing between engine components. In some engines, this may lead to internal damage if components come into contact with each other.

There is not always a clear warning before a timing belt or tensioner fails, which is why periodic inspection and timely replacement are important.


If you’re unsure about the condition of your timing belt tensioner, proper testing is recommended. The team at Blackwell Automotivemay begin with an inspection as part of our auto diagnostics service and evaluate related components within the engine repair system.


If your timing belt tensioner may need to be inspected, call (602) 992-5478 today.
