hello i have a mercedes E220 cdi.the last 6 months i had to replace the fan belt every month .my mechanic has changed 2 pulleys one for power steering and the tension-er pulley and still fan belt slips off as today was the 7th time.any clues what else shall i change please as getting fed up.i don't want to lose the car as recently i reconditioned the gear box. there is no obvious leak from oil from the turbo or fuel as he replaced some fuel pipes. Today he told me was soaked with diesel the fan belt and slipped straight away but he cant identify from where is the leak.haven't heard or seen this before in those cars. i would appreciate if you can help.
I have heard nothing and still my problem is on going.i would appreciate to have an answer to help me resolve this matter.if you cant please refund my 15 pounds.
