Why is my timing belt screeching?
Failing Water Pump Pulley: The most common cause of squealing or squeaking from the timing belt cover is the water pump pulley. If the bearings in the pulley are beginning to fail, they will make noise. Serpentine or V-Belt Slipping: Another common cause here is noise transference from a slipping serpentine or V-belt.
Can you overtighten a timing belt?
Help! Dear Anthony: A belt should never be over-tightened. An over-tightened belt can burn out any bearing that the belt rotates on, including alternator, power steering pump, A/C compressor, idler pulleys, etc. An over-tightened timing belt can ruin any pulley bearing it is connected with.
How tight does a timing belt need to be?
timing belt isn’t like a drive belt, you shouldn’t be able to twist it at all. You check it by pulling it away from the gears. It should only move about a quarter inch, so pretty tight, but not tight like it’s gonna snap.
Is the timing belt tension too high or too low?
Timing belt tension should not be too high or too low. Too low a tension can also lead to shortened timing belt life or ratcheting, while too high a tension will add undue stress to bearings, shafts and other related components. In addition to design considerations, there are several other accepted methods of reducing belt drive noise:
How do you install a new timing belt?
Install the new timing belt over the timing belt pulleys. Do not pry or use force, loosen the motor mount and/or mounting brackets to loosely install the timing belt. NEVER PRY ON A TIMING BELT, PRYING THE TIMING BELT WILL DAMAGE THE TIMING BELT PULLEYS TEETH AND/OR FLANGE THAT YOU ARE LEVERAGING AGAINST.
What are the symptoms of a faulty timing belt?
Ticking noise coming from the engine. The timing belt is attached by way of a series of pulleys to the engine’s crank and cam shaft. The crankshaft powers the engine’s connecting rods which are attached to pistons inside the combustion chamber. The camshaft operates the cylinder head valves and rocker arm assembly, which…
Can a timing belt be removed without prying?
Loosen motor mounting bolts. Move motor until existing timing belt is slack and can be removed without prying. NEVER PRY OFF A TIMING BELT, PRYING THE TIMING BELT WILL DAMAGE THE TIMING BELT PULLEYS TEETH AND/OR FLANGE THAT YOU ARE LEVERAGING AGAINST. Remove old timing belt and check the timing belt for unusual wear.
