HI all had my car in on friday to diagnose a noise coming from the belt pulley area ? mechanic said to me straight away its the crankshaft pulley great i said sort it out 3 hours later i phoned him to c if i could pick it up he said yes was not the crankshaft pulley it was just a belt and the tensioner. Pulley is fine paid him 152 quid job done great off i went with no noise from that area. Saturday went out started car BANG IT WAS THE CRANSHAFT PULLEY phoned him told him my belt was lying on the floor .He said if its down to us he would sort it out straight away no charge now he is saying the pulley was fine on friday but he will fit new crankshaft pulley for free but ive got to buy the part ?. Do you guys think this is right should he not of knew it was fooked when he checked it .Has the belt been to tight and pulled it off i just dont know, what do you guys think peter
