Hi, having read a lot of posts on cambelt, water pump change and as my water pump is leaking, I think it is the pump as i have to top up every 3/4 weeks and there is water drops on garage floor under pump. Some say that the pump may sieze shredding the belt but when i look at mine the water pump is at the front of the engine and is bigger than the alternater, not the size i was expecting and it is driven by a grooved belt which also drives the alternator. I think mine is a diff, set-up as when i look at kits on ebay, water pump and belts the pump has a gear wheel , is much smaller than mine. I have 54k on clock. 55 reg, facelift model. ty.
