Water Pump O-Ring

Hello,

After reading almost all of these forums on "water pump replacement" i have found no answer for my question. Im looking for the location of where the "rubber o-ring" goes on the water pump on my 90 N/A mx6. after removing the pump, there was no o-ring to be seen. Any help or pics would be really appreciated as i need to get this thing back on the road in less than a day. THanks!

And not only that, but half of the pictures that seem to be attached in the forum dont seem to load on google chrome for some reason.

Chances are those pictures are very old and no longer exist.

According to the WSM there are no o-rings required on the water pump. I don't remember having to use one when I did the same replacement.

The only O-ring I know of goes on the heater return pipe

Ive had a few replacement water pumps that came with an o-ring. They have a machined recess where the o-ring seats so it seals to the block. I think nowadays they are mostly an odd and somewhat rare item.

If yours does not have an o-ring, then it uses a metal compression gasket (some replacements will include a fiber gasket) to seal things up.

Good luck

Thanks for the feedback. Completed my engine rebuild, and all started up nicely. Just having some idling ups and downs and whirring from the water pump area.
