My duaghters Sportrack has a strange fault. When it is first started in the morning when it is cold, i.e. a frost, There is a loud knocking noise coming from the front of the engine around the water pump/alternater/fan. This does not increase with engine revs. As soon as the engine gets warm all is fine and the engine is as smoth as can be. If it is warm in the morning, above about 2 degrees there is no noise at all. For the life of me I can't find where it is comming from and it is pointless taking it to a garage or where we bought it from (still under warrenty for 6 weeks, as by the time we get it there the noise has gone .
Any one any idea's as I'm now stumpped !!!!
