Hey guys...

Last week i took my car into the garage to have the Auxhillary belt replaced, as it was making a whining sound. After getting it back, the noise was still there slightly, and the engine made a vibrating type noise. Anyway i ignored it, and the following day the car wouldnt start... *dash LED turned into ---, Red temp warning light was on as well as engine management light*. after 15 mins it started no problem and hasnt happened since. since then the noise in the engine has got much worse.. when i lower the clutch the engine sounds like its going to fall out, very tinny and rattly, any use of the clutch causes the extra noise. I have taken it to 2 garages, one thinks its just the Crank pulley or the tentioner, the other thinks its the DMF... Does anyone have any idea which it could be?

Its a 2002 mondeo, 217k miles.

Thanks!
