Sorry, I was thinking the large nipple (where hot coolant is pumped into the top of the radiator) was your problem. For the small one ( not present on my 1980 300 TDs) your solution sounds great.
As for my own situation, I had the big upper nipple break in the summer of 2005, and I swapped out the radiator with a spare that I had, and that was fine until a couple of weeks ago, when it developed a bad leak at the back side of the upper tank. So I have just completed the copper pipe/epoxy repair on the rad that has been in the waiting room since 2005. I used Goop Superweld epoxy paste. And just today I received from Fastlane the new transmission cooler hose to replace the one I ruined trying to remove the leaking radiator, so tomorrow I plan to finish the installation, refill with MB coolant and de-ionized water, and fire it up. I think it will last a long time. Steve Last edited by Sbean; 11-01-2006 at 11:40 PM. |

A temporarily permanent repair that has worked for me is to us Shoe Goo to seal the connection. You will need to put some alcohol (non-consumptive) on a rag and wipe the area down to remove oils, dirt, coolant residue, etc., then apply a moderately generous amount. Follow the directions for set up time. Shoe Goo is pretty common and can be found at discount stores and such.
As I said, it is temporarily permanent because I have used it to repair a hole in an old rear tractor tire and the connection to our window washer fluid line that broke at the reservoir cap years ago. The w/w fluid line needs redoing, mostly from having to manipulate it so much during the repairs recently done and the fact that the reservoir cap is opened to add fluid. The tire is still going strong. I did the original repairs with Shoe Goo because I had nothing else at hand and wanted an immediate temporary repair until I could do something better, such as get to the dealer to order new parts, which I didn't do because the Shoe Goo kept working. Shoe Goo is not a proper repair but it is some amazing stuff. Jim W. |

I did this repair, sorry I haven't posted a picture yet.
I bought a 3/8" brass (I think) valve from pep boys. I cut off the old, melted, destroyed stem from the top of the radiator. I drilled a 3/8" hole into the old hole and screwed the new metal stem in, then I sealed it up with some JB weld. Worked like a charm. No leaks. I'll try to get to posting a picture.

I don’t recall if its spelled right but I think the name is Marine tek a super strong epoxy a mechanic used to repair cracks at the head on gas engines, and they hold yes am not kidding I repaired a plastic radiator back in1995 and still holding as new, before that I try epoxy but as soon as it was hot and with pressure it soften and start leaking , the only draw back the marine tek is liquid and takes 24 hrs to harden, what I did I use masking tape shaped like a ½ cup to hold the marine tek in the place I needed it was tricky but it work you can find the stuff at a major auto parts stores or aircraft supply places back then was about $15.00 for ½ an ounce of both the catalyst and the resin.

I REALLY REALLY like my new Behr radiator, and the new hoses, and the new coolant, and the sense of peace of mind.
Tried the epoxy fix, with very short term success, and the nipple broke off in the hose with no trouble at all. Just can't get the car up to 90 degrees in the first quarter mile anymore though....
