hi all ive got a strange engine noise coming from my escort cossie. it only happens when the car is hot and run up to temperature. plus it occours at 2000rpm its a sort of gurguling ratteling noise can anyone help.?

 

i had one on a customers car and it turned out to be pre- tensioner on the fan belt . take the belt off check the bearing also check alternator ,poweersteering pump and air con , run car without belt to see if noise has gone . regards joe
