Frequently Asked Questions
How many miles does a serpentine belt tensioner last?
Typically, serpentine belts last anywhere from 50,000 to 100,000 miles.
What are the symptoms of a bad belt tensioner?
Tension Loss
If the belt makes a squealing noise or an accessory within the system has stopped working completely, it's a sign that there is tension loss.
What causes a drive belt tensioner to go bad?
Causes Of Timing Belt Tensioner Failure
Over time, the spring stretches out and loses its tension. As a result, the entire tensioner becomes too weak. Dirt and dust build-up on the timing belt tensioner pulley: When this happens, the pulley will fail to support the timing belt. It may cause the timing belt to slip off.
Can I drive my car with a bad belt tensioner?
Driving with a bad tensioner pulley is not advisable, as it can lead to significant engine damage and potential breakdown. The tensioner pulley is crucial for maintaining proper tension on the serpentine belt, which drives various accessories in the engine.
How do I know if I need a new tensioner?
Firstly, the most common sign of a bad tensioner is noise from the belts or the tensioner itself. Squeaking or squealing may occur, especially during startup, indicating a loose tensioner.
