Ok followed my first rule and searched the forum for information but did not find any.

I have a coolant plug start leaking. Have not pulled it yet but wondered what options others have found for a replacement short of buying one from FS....

Anyone know the size/thread pitch ?
Replacement ideas other than rubber plug, putting back the original with sealer etc....

Not worrried about getting it out that I can handle, just what I can put back in case the plug is to far gone.
Hope it's not the bung leaking instead...

Will did finally find this post that says what the size might be if it's correct.

Bump for the day...
I also check more and looks like the plug has rusted through in the hex hole..

Anyone have luck with finding any replacements. Does not sound like a home depot plug is quite the right size from what the post talks about...

Last time I had the coolant pipe plug out, I went to a few hardware stores to see if I could find a replacement.
The closest threads that I could match up was a metric M10 by 1.0 mm thread pitch bolt. Since the plug is a "pipe plug" it has tapered threads.
So far, I have not located a local vendor that has metric pipe plugs.

From the P-22 manual, it shows the parts as a Plug, Engine Coolant, #10040001.
The part shows up on Monster and GMPartsDirect.

Thanks, that is what I was afraid of... looks like it's down to seeing if there are any fair ones at the u-pull-it or order from FS or the places you listed...

well, as a workaround, if you can get it out, just drill out the hex hole and tap it and put a ss bolt in with a little teflon tape.. could even do that in car, easily. Likely a 1/4 20 would work, maybe even a 5/16-18.

I have never touched mine after I stripped out the hex part trying to pull one, decided that it is a problem to be addressed if it leaks.
I just trun the hose down to a jug and blow em out if I want to completely remove the fluid from the tubes.

Fiero store has them.




84-88 COOLANT TUBE DRAIN PLUG
Part # 60001
Price: $6.25

i've always just used brass 1/8 pipe plug.

Me too, used 1/8" NPT brass plug, ,no problem screwed in by hand and tightened right up no leaks. Drained and put back in still no problems.

Well problem solved, it was not the plug, was actuall they hose clamp on the hose coming from the water pump.
Somehow ( mark it a one of those weird things that happen) the coolant was running down the top side of the pipe and did not come around the pipe until it go to the horz. part where the plug is. Much have been following the undercoating on the pipe...
Pipe was not wet below the clamp that you could see only after I put my fingers on the top of the pipe did I find it.

Tighten the clamp and it's all better....
