1998 Toyota Camry 4-cyl.Engine starts and runs, but makes a horrible, random clunking sound that seems to come from the water pump area. Coolant was seeping from front cover, appeared to be from water pump area again. engine idles, but wont rev up at all.My guess is that a bearing let loose or a vane broke off the water pump and is bouncing around inside, triggering the knock sensor which pulls out all of the timing, not letting it rev. Sound right?If that is the problem, what all is involved in replacing the water pump? Its my roommate's car, but I told him I would fix it if possible to save some money. I'm a fairly competent mechanic, but I don't have the best setup here while I'm away at school, so any info on how involved this will be, how many hours of labor is listed for that, or anything to watch for from someone who has had a similar problem before would be greatly appreciated.
1998 Toyota Camry Water Pump
water pump is driven by timing belt. need to replace together. water pump may have threw belt off, explaining no acceleration. weekend job, use new pump, vs. reman. get set with belt and new tensioner.
If you are going to do this, have him buy a book at the auto parts store.
