Im new to the forum so forgive mw if this has been discussed before! My 2004 i-ctdi started making a chug chug sort of noise and started making loud squeaking noises. Took it a local garage and they said it was the alternator and I could drive it until I got a refurbished one which has arrived. So I drive the car a little and the noise became very loud and the engine ground to a halt! Tried to start the car but it was like the battery was flat as it struggled to turn the engine. The recovery man said the battery was fine and suggested the engine may have seized as if it was the alternator then the belt would just slip. The belt is routed the old way which I have found out causes the bearings in the alternator to seize. Is it possible the belt is so tight that it cant slip and hence I cant start the engine ***uming the alternator has seized.
