I was wondewring if anyone knew how much work is involved in changing a water pump on a 1.5 turbo diesel nova. I dont know if the cambelt runs around the pump or not, it doesnt look as if it does when I peer into the murky depths of the engine bay!! I think the engine is an isuzu lump if that is any help

PS if anyone can help let me know as soon as, because I have a long run to go on this Sat and it is leaking like a drain !!
