2000 megane strange noice from aux belt
Posted: Sun Jan 11, 2009 5:50 pm
Hi I have been having problems with my auxillary belt and its components over the past 6 months. Anyway to cut a long story short, first I renewed the Steering pump as the belt was too tight and damaged the bearings in the pump, I renewed the belt as well. after a while I noticed this strange rattling sound when the engine was started from cold, but after a while when the car had warmed up the noise went, and it sounded fine. So I decided to renew the belt tensioner pulley as it appeard the noise was coming from there, again I renewed the belt as well. All appeared fine for a while, now this rattling noise has returned, but it only happens when you first start the car, more noticible if its cold weather, its not like a fanbelt screeching/slipping noise, more like a rattling noise. but as I said after driving about a mile it stops, and the engine sounds perfect. I am wondering if my fan belt is too loose or too tight, I am a bit dubious about overtightening the belt as last time it wrecked the steering pump. any ideas anybody please
thanks
Roger
