Times are hard and I'm a poor artist. My car has done 203K miles. I need to replace a leaky noisy water pump and have a few questions - is it possible to change out the water pump easily without faffing about with the whole timing kit? I know people will say that I should replace the whole lot for the minimal cost, but if the belt looks good and there are no other rattles or squeaks I don't see why I can't try to save a few quid and a bit of effort on what is an old banger (yet which could still do another couple of hundred thousand miles!!). Thoughts on best water pumps axial/ centrifugal and plastic vs metal impellor issue?
