Why is my belt jumping?
Slipping can be the result of a loss of belt tension (or a weak automatic tensioner) or pulley misalignment. When the belt slips off the track, the friction between the belt and accessory drive pulleys causes the belt to overheat.
Why did the serpentine belt come off my car?
Answer: There are several reasons why the serpentine belt could come off your vehicle, or any other vehicle. The most common reason is that the serpentine belt is just worn out and needs to be replaced. Another common cause is that the belt tensioner is froze / stuck and not functioning.
What happens when you change the timing belt?
He changed the timing belt, drive belts, water pump, pulleys, tensioner and a few hoses, and everything seemed to go off without a hitch. After picking up the car, though, we noticed that the idle seemed much rougher than it had in the past.
What happens when a belt is worn out on a car?
What happens is that the bearing for any of these pulleys the belt rides on is worn out, so the pulley either wobbles or does not sit flat and gives the belt a chance to “walk” off the pulley. A worn out pulley will usually be accompanied by a growl or whining noise when the engine is running.
Why does my serpentine belt make a squealing noise?
My car has 134000 miles. Noise of that type is due to a failed or failing bearing in one of the pulleys or accessories (e.g., alternator, water pump, A/C compressor) that is driven by the serpentine belt, the belt is not properly tensioned, or the rotating pulleys driven by the belt are not all in the same plane.
Why are my serpentine belts squealing after replacing?
Just replaced both serpentine belts in my car, was not running into any kind of squealing before, but had not replaced the belts yet and the car was up to 90k miles. After replacing the belts, they started squealing.
How do you change a serpentine car belt?
If you can find some instructions on how to change the belt they should tell you how tight it should be, but if you can depress it more than half an inch with your fingers (when the engine is off, of course!!!) it’s probably too loose. Loosen both bolts, then push the alternator as hard as you can to tension the belt while you tighten the top bolt.
What makes a belt slip on a car?
The tensioner is a spring-loaded device that holds the belt tightly against the pulleys of each of these accessories. The spring becomes weaker over time and allows the belt to slip when the demand for power for these accessories is high.
Why does my timing belt come off after 13 years?
It is very possible that after 13 years the rubber mount is just collapsed. The top mount usually comes off to allow the belt to go around the cam and the full engine weight rests on the front mount by the radiator core support… that will usually be the issue related to the vibration Thank you all for the prompt reply.
