Water Pump plug?

[Fluxn83]

After having my water pump swapped out (complete assembly), it was brought to my attention that in the kit, there was no replacement for a plug that is supposed to go into a specific hole.

(For a better visual, look at http://store.delorean.com/popup.aspx...rge/102119.JPG above the pulley just to the right. The hole facing the viewer)


When I asked DMCH, it was explained there was no replacement for it, and that owners just re-use the old one. Does anyone know what it's proper name is, the function, and where I can procure a replacement? Thank you!

This is unfortunate, I take it you did not do a direct R & R of the pump swap. Meaning the pump was removed and tossed before you had the new Replacement on hand. The only way I can think of for your to get the plug is find one from a Engine swap owner or parts car. You should also contact Other DMC service facilities. EU guys are really good at sourcing some of the obscure bits and pieces too.

Thankfully, it was my mechanic who did the work, and he didn't toss the old water pump. The old plug was used in the new swap, so that's taken care of. I just wanted to know for future reference. I appreciate the concern.

My water pump has a Dorman 65256 installed in the front port. $4 from Advance Auto.

There are forum threads that say you can use an NPT plug in that spot but it may not seal properly and will bugger-up the metric threads.

The oil drain plug? Does it work decently enough?

You probably should have mentioned this in the first post. You gave the impression you needed one, rather where could I get one IF I wanted to replace it with a NEW one.

It’s been a long time since I did A WP swap and don’t recall what the thread size is. I would imagine a metric Oil plug would work with gasket if you new the thread size. For some reason I’m thinking it was a very odd thread pitch though. Something none standard.

I apologize, and do appreciate the advice. I was told mine looked a bit rough, so that's the main reason I was asking (which should also have been in the first post).

Yeah its a metric thread plug. I bought a new stainless one when I put a Volvo pump on my car.

Nice, where did you get it?

Just checked, and it is a 12mm drain plug. Bought it from Belmetric: https://www.belmetric.com/12mm-metri...ug-p-6073.html


I also used another plug (I think it's 14mm?) to delete the thermotime switch. Dave's hot start relay replaced that.👍
