coolant expansion tank

[motorman]

hello gents,

speedt the weekend cleaning up some loose ends on my M1009.

one thing i have traced but not fixed is a coolant leak.

i have discovered that the expansion tank has a small leak on the bottom seam where the 2 pieces of injection mould come togeter.

does anyone have an idea for a fix?

can i just glue it? melt it?

any advise is appreciated.

best regards
m

DUCT TAPE just kidding but JB weld might work

JB weld should work great for you.

Other companies make some plastic welding supplies.

A while back I cross referenced the coolant tank to a NAPA number.

I don't know if it is the exact tank but here is the info.

GM number - 14052221
NAPA number - BK6053401

I used a green stick of plastic, melted with my torch. A lot of guys use them to plug holes on flat bottom boats.
I got mine from the local Car Quest.

Zip ties work also to weld the crack back together with an soldering iron.

Anyone know.why A3s do not have a coolant expansion/recovery tank?

My grandpa used a high temperature epoxy to fix a dish washer leak once. Might work for hot coolant as well. I would just get a new tank though.

That expansion tank was still available at the dealer three years ago, or so. About $25 retail, as i recall. The part number should still be molded into your tank, mine was. The last four digits were all twos, sorry i can't remember the whole number right now. I've been awake for about thirty hours, and i am about to get real crabby. Post back here if you can't find the number on your tank, and i'll skin the number off of mine for you.

It's not uncomon the overflow tanks develop seam splits. LMC and Classic Industries carry replacements as do other sources.

Yes you did. And i completely missed it. My apologies. It looks like my eyes are getting as bad as my memory: there were THREE twos. I'm gonna chalk it up to "PWE". That is, Posting While Exhausted.
