Loose belt-tighten or worn idler pulley bearings.Tighten belts first and if the squeel is still there remove belt and check all pulley bearings.Grab the pulley by hand and give it a wriggle-there shouldn't be any play axially
Hi. Is it the pulley or the belt which is making the noise? if the belt is the problem the it may just need adjusted (tightened) if not it may be something more sinister but try the belt adjustment first.....
1. Disconnect battery.2. make sure the engine is at top dead center(TDC).3. take belts off.4. Remove pulleys,except for the camshaft pulley..5. Remove timing belt cover.At this point you should see the timing belt and also the water pump,if it's not external.I suggest while you have access to the water pump that you replace it.6. loosen timing belt tensioner and and finally remove belt.On the camshaft pulley,there should be a notch,making sure the notch is at the top of the pulley. 7. Tighten the timing belt,but not too tight.7. Installation is reverse of removal.
you call it the serpentine belt, we call it the fanbelt.it,needs tightening,slightly loosen the alternator, then pull away from engine and tighten belt, tight enough when you can move longest part of the belt, between pulleys, 1/2 inch in/out.
if squeel re occurs fit new belt.

You have a loose belt or it is glazed. The reason why it quites down after a while is because the belt heats up, and cause better grip on the pulley. Solution: replace belt and tighten properly. If the problem persist, then it is the the idler bearing that is going bad. If it is equiped with that.
i recently experienced the same issue. it can be your tensioner pulley or your water pump see the belts are connected to the pulleys and sometimes get worn out and need to be replaced. especially on a older car see a mecanic
