What does a loose belt tensioner sound like?
If the drive belt noise resembles a squeal or a squeak, it is possible that the belt tensioner is loose. This is especially the case when starting the engine first thing in the morning. Since the tensioner is not able to maintain the correct tension on the belts, it produces a squealing or squeaking sound.
Can a bad belt tensioner cause a belt to break?
The belt can break due to a number of reasons, but the most common is age. One other common problem is the belt tensioner. If the tensioner is bad, it can cause the belt to come loose or cause the pulley to seize, making the belt come off.
Why does the tensioner make a squeaking noise?
Since the tensioner is not able to maintain the correct tension on the belts, it produces a squealing or squeaking sound. This is most evident on the drive belts. 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.
What’s the purpose of a timing belt tensioner?
Part 1 of 6: Purpose of the belt tensioner. The timing belt tensioner is used to do just that – keep tension on the timing belt. The timing belt is a rubber belt that runs over and through a series of pulleys and gears. Over time, due to age and heat, the belt will stretch out.

Why does my idler pulley squeal when I Turn on the engine?
Another common symptom of a possible issue with the idler pulley is squealing from the engine belts. If the surface of the idler pulley wears, or the pulley seizes or binds it may cause the engine belt to squeal as a result of it rubbing against the surface of the pulley.
Can a bad belt tensioner cause a car to break?
In more severe instances, a bad tensioner pulley can cause the drive belt to break. 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.
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
1. Grinding or squeaking noise from the belts or tensioner. If the tensioner is loose the belts may squeak or squeal, especially when the engine is first started. It is also possible for the tensioner pulley or bearing to wear out, in which case the vehicle will produce a grinding noise from the pulley.
What happens if timing belt is loose?
Also, when your timing belt is loose, it will cause some drivability issues usually under high load or high rpm. If your timing belt is not properly tensioned it will not keep the valves timed properly to the lower end and this will cause misfires, loss of power, bucking, and could even cause a no start condition.
When to replace the timing belt on a water pump?
When replacing a water pump run by a timing belt, always replace the timing belt at the same time, especially if the water pump was leaking. A coolant contaminated timing belt will have a reduced service life. On the other hand, a worn out timing belt may break and damage your new water pump.
