My friend wants to buy a 90's somethin dodge avenger.( not sure what year) and the guy says the water pump is bad. Does the car have to be re timed when u replace the water pump?
Yep, but it's not as bad as you would think, but bad enough to take a weekend.
There is no connection between the water pump and the timing. Timing is a function of the engine ignition system, water pumps are part of the cooling system. There is no relationship. The water pump is driven by the belt that drives all the other engine accessories. Changing a water pump does not in any way effect timing.
