my friend owns a fiat punto 1.2SX60. Its about 10 years old. Shes owned it 5 months. When driving it, when engine is relatively cold..it makes a squeeling sound. If you take foot of accelerator the noise stops.
any ideas what it could be?
Could be a tesnioer pully on the timing belt, but when the engine is runnig, you should still hear a whine. If not could be the alterntor belt, or the alternator possibly.
check how tight the belt is with your finger it should not have more than 1 inch of "give" in either direction
