Fans running a lot??

All I see is a gasket and a O ring on that pump no plug . Its a One piece gasket that also goes around the bleeder hole.

The O ring looks separate.

The gasket has a round part that seals a small bleeder hole in the block. Its about 1/2 in in diameter and attached to the gasket with the 2 larger rectangular openings. Thats where I thought the mystery plug went. I'll be pulling the pump soonest and get the mystery plug ready for photography.

Triker,
Thanks a lot for hanging in there with me in this " adventure". If I'm the guinea pig on this waterpump thing here is my word of advice------ Don't

Sure like to see a picture but pretty sure none of those are blocked on the gasket. They should all be open to let the coolant pass thru.

Be waiting for that picture.

And now of course I'm having trouble uploading pictures:cus:

 

[Lew L]

Had to use another computer. I think it was the size of the file ---- which I shrunk.

 

[trikermutha]

Is that one of the bolt sleeves?

I dont see anything else that could be it except a bolt sleeve??

I really dont think it goes in the bleeder hole at all.

 

[trikermutha]

Like to see the pump too. Gasket side.

I'll wiggle the pump out later. It surely isn't a bolt sleeve as it's solid with the washer( magnetic) like end swaged ont to what looks like copper rod.

 

[trikermutha]

Are you sure it came out of the pump or did you find it laying around?

It fell out as I removed the pump, did I see it actually fall out---no as it's awfully tight in there.

 

[trikermutha]

I looked at several pictures of the pump and see no where that could be on it. Even found a picture of the impeller. I wonder if that was laying in the top of the pump and when you removed it it fell out?

Unless some else chimes in and knows where it goes I see no need to use it on the pump..

I have no Idea Copper round disk with pin through it, I don't know what the thermostat looks like but maybe part of that. let the guessing game begin. :joke: opcorn:

 

[trikermutha]

Maybe check with the dealer service dept if they know where that sleeve goes? Can't hurt to ask.

Found these pics on ebay
This link shows #2 flat head screw? https://www.cheapcycleparts.com/oemparts/a/cam/5c2f751d87a8661634626acf/engine-cooling
My guess its a piece of the old thermostat!

 

[K80Shooter]

Post pics of the old thermostat, that could help explain things.

That screw holds the cooling pump DRIVING gear to the cam shaft...........

To get the the old thermostat I have to cut up the old pump which I'll probably do

.

K80---- you're the winner!!!! I cut out the old thermostat and the "Mystery plug" is part of it. The thermostat is NOT made to come out!! I used a dremel saw and cut the locking tabs as I'll NEVER use the old water pump again. the plug helps center a spring under the thermostat. The mystery is how it got loose????

Now to put it all back together--------------

EDIT: old thermostat worked. mystery plug stopped it from opening to far. Could see wear marks in the right spots and right sizes to stop thermostat expansion. I don't know how it got loose, It's kinda locked in place by a plate and spring.

 

[trikermutha]

Alright. Solved that mistory..

So the leak has stopped?
