Changing the Heater Core,What a pain this is. While replacing a part a tab broke off. Does anyone have such a thing. Thanks John

I guess I'll have to use JB Weld Plastic to fix this. This part is hard to find.

I broke the same part on mine but luckily I could get one out of a spare box that was good.

If you are creative, you can get some fiberglass gorilla hair body filler to make the repair. Or use fiberglass sheets and the 2 part epoxy. Nasty smelling stuff, but does work good once complete. You can do it in steps to just try and get a rough form on first layer then once set up, build it up on other side.

Works good and should be plenty strong enough.

Of course finding a replacement is also good...but if it's at a pick n pull, you get to do the whole thing all over again!

Heater core is not fun. You just have to take your time and devote a lot of time. Don't be in a rush to get it done so you can make that date with your wife/girlfriend. But satisfying once done!

Thanks everyone, I seen a few videos about using JB. Seems like it hardens up pretty good. Going that route. Also I thought I had another box,but with all the stuff I have been collection, you know what I mean.

Thanks John

Be careful with theses guys. They will show a part available, let you buy it then cancel the order because the part is not available. This is incredibly frustrating.

Thanks everyone, I used the jb today,and it is now put back together. I did not apply any pressure on the repaired part. Went back nice and easy.

Thanks Again, John
