It's probably the drive belt and they tend to make noise when they are getting stretched. You can either try tightening it, if it is able to be and not have a tensioner assy, or replace the belt.
iwhat does the noise sound like. most likely a worn belt or belt tensioner if its a high pitched squealing noise.
You will need to tell the year, make and model. All are different.
yes, if the tensioner is bad it will make a noise at idle, but when you rev it up the chain will get tighter and the noise will go away.
When a timing belt is going bad it can make a high-pitched screeching sound. It can sound like a high-pitch whirring noise. Not all timing belts make a noise when they are worn or going bad.
Assuming you have already checked the obvious, the serpentine belt tensioner and belt. A common cause of the squeal in 4.0 Ford engines is the camshaft sychronizer (takes the place of the distributor on DIS, distributorless ignition systems). It sounds very similar to a belt squeal and is often mis-diagnosed as a belt being loose or worn. The noise can be intermittant, but if the noise is there when you have the hood up use a simple mechanic's stethoscope to help pinpoint the source of the noise. == == The most likely culprit is a serpentine belt or the belt tensioner. Try replacing the serpentine belt. If the noise persists, replace the belt tensioner. See the related article "Serpentine belt and Tensioner FAQ for the Ford Explorer all models"
You just need to remove the bottom cover on the side where the timing belt is. Then loosen up the bolt on the tensioner, then use pry bar then when when the belt is tight, tighten the tensioner back up. (make sure Your TDC (Top Dead Center)) ;)
Check all belts and anything that was removed while changing the timing belt, to make sure that nothing was damaged. If everything is ok, then the timing belt may be loose.
we have one and what the dealer fails to tell you is that the timing belt needs to be replaced at 60,000 miles, We found out the hard way and it cost us 3,000 the tensioner failed and it destroyed everything,tensioner,timing belt,shroud cover,belt valves, rods,serpinteen belt,,Make another choice
Loosen the timing belt tensioner so the belt will have some slack before removing it from a 1985 Honda Civic. Remove the old belt. Install the new belt and make sure the engine is TDC.
If your vehicle has a timing belt and not a chain, you need to replace it immediately. My distributor made the same ticking noise and it turned out to be the timing belt had a frayed piece on it and this piece was the source of the noise. Before I could figure it out, the belt broke and left me stranded on the roadside.
yes you do have to loosen the nut on the tensioner, or else u wont have ennough slack in the belt to put it on, once it is in place then make shure u tighten the bolt again
