Can a bad tensioner cause a belt to break?
More often than not, it is actually the tensioner that goes bad, not always the belt (unless it is really old). Most of the time a belt will break due to a seized pulley or bad tensioner allowing it to contact the timing cover.
Can a bad belt pulley cause a car to break?
In more severe instances, a bad tensioner pulley can cause the drive belt to break. Failure of the Belt-driven Accessories to Operate Since the belt tensioner keeps the proper spinning of the drive belts in the car’s engine, certain components or accessories may fail to operate if there’s a problem with the tensioner.
How do you loosen a timing belt tensioner?
The bolt in the center of the tensioner secures it to the engine block. Use a ratchet wrench 1⁄ 2 to 3⁄ 4 in (1.3 to 1.9 cm) in size to loosen the bolt. Rotate the tensioner away from the belt first as far as possible, then reverse direction. Note any problems you experience.

Why does my belt tensioner make a grinding noise?
If the noise you hear is similar to a grinding sound, then it is possible that the tensioner bearings or the tensioner pulley is the problem. These parts tend to wear out. This is what causes the grinding noise since the metal parts will be rubbing against each other. This is another symptom of a failing belt tensioner.
What causes belt to slip on idler pulley?
Over time, as the pulley spins against the belt, both components will eventually start to wear. This may lead to visible scoring marks on the surface of the pulley, as a result of contact with the belt. Eventually the pulley and belt will wear to the point of reducing tension, which may lead to the belt slipping. 2. Belt squealing
