I just bought a used Auxiliary Cooling Pump for my 87 951, because it does not work. I just took a look at the part and it is the top cylindar shaped pump, but when I took a closer look there is a small black piece under the pump that has antifreeze leaking from it. I took a picture and attached it so everyone can see what I mean.

Could someone please assist on why that is leaking, and what that part is/what it does etc? Would changing the Aux. Cooling pump fix the leak?

That's pretty common
The O Ring is leaking ...
I replaced mine with an O Ring from OSH Hardware
Not a easy O ring to find ....
but its pretty easy to take apart
The screws are usually pretty rusted .. but because its in plastic its easy to take apart
Good Luck

Do you have a link for the exact part you used? Could I get it somewhere else we don't have osh around here. Also what is that black part?

Thanks!

Crazy Eddie

I will see if I still have the box they came in ... there is no link, but they probably have a website
As for the black part ? .... That's one unit, the whole thing is the aux WP ( but it comes apart )

The O ring part # is 0624 1 7/16ID- 1 5/8OD x 3/32 wall
Where are you located ?

I'm in Massachusetts. Where could I buy that from?

Crazy Eddie

With the measurements I gave you call the a plumbing supply or a really good HW store.... If you can't find it I can buy you one and send it to you ....
