The timing belt tensioner holds the timing belt tightly against multiple pulleys including camshaft pulleys, crankshaft pulleys, water pump pulleys, and idler pulleys.
The teeth of the crankshaft pulley and camshaft pulley are marked. These marks line up precisely with the grooves on the timing belt for proper engine timing.
There are several possible symptoms of a failed timing belt tensioner. Some symptoms are gradual, while others are very sudden. Heeding the early warning signs is critical to avoiding costly engine repairs. The following are common symptoms:
Check Engine Light - The check engine light may come on due to engine timing and misfire issues.
Engine Performance Issues - The engine may run rough or exhibit a loss of power due to incorrect engine timing.
Engine won't start - The engine may start but won't start due to closed valve timing or the engine has been damaged.
Engine Noise - A failing timing belt tensioner may wear out from damaged bearings, or rattle from losing tension on the belt.
Engine failure - A damaged timing belt tensioner can cause the belt to slip, affecting the timing. If the piston touches the valve, catastrophic engine failure can occur.
