I need to replace my water pump

just buy one

well, I hate to tell you, but they never made such a beast. 1994 Mazda 323 , with a 2.0 lt engine, and also no v6 was ever installed in a 323, now if you have the original engine that will be a 4 cylinder 1.6 liter timing mark on the crank and cam is at 12 o'clok., the cam says up, and you line up the mark at 3 o'clock, to the block, i hope you changed the water pump, coolant and rolers ?

first you need to find out if the pump is internal or external. If external then you can do it. If it is internal then you will need to tear down front of motor which can be a job. depends on how much you know about working on cars.If internal pump you will need to set the timing again and in alot of cases you have to remove motor mounts remove pullies and on and on. can be a big job. most external pumps are not that hard to change.

Sorry to say you have a blown head gasket. Lee

Did you use an impact to change the water pump? If you did not and reversed the rotation of the engine you bent a valve stem. Dohc has this quirk

You don't have your engine size posted so pick the applicable application:

1989 Mazda MPV
2.6 liter SOHC L4

1989 Mazda MPV 2WD
3.0 liter DOHC V-6

try calling a junkyard and see if they will tell you the enterchange ok good luck

Yea there should be a gasket/O-ring. Problem is the only place to get just that part is probable the dealer.

I think that you have a drain line cloght locate
the ac drain line and uncloght it.
