I recently had a new water pump fitted, although its all working fine whenever my car is started from cold though there is this horrible squeeking/ chirping it sounds like a belt is slipping. Ive had it back in the garage recently for a winter service and a couple of other things and i did mention it to the garage then and they have had a listen and checked the belt and they say they dont no why its doing it because the belt is on tight enough and its in good condition but im sure its only just started after the water pump was fitted or it could be the cold, its pissing me off its just one thing after another with this car. could it be the water pump itself? shorly something can be done?? It sounds terrible.......
