anyone ever repaired a crack in a plastic radiator?

yeah, I used jb plastic weld I found at wal-marts, It was for a crack on the top of my old 88 rad, it worked for about 2weeks at a time. I got an 86' metal one now though so no plastic problems

damn, two weeks sucks :[ it was worth asking though

You can take it to any RAD shop and they can replace the TOP clip part or bottum. Now is a good time as any to get a KOYO RAD they are on Ebay now for 275$ I got mine from the same dood selling them and great packaging and respectable shiping time.

I used regular JB Weld on one, and it lasted for a month, then I pried it up, sanded the whole area with 80 grit sandpaper and did it again - 2 years and still holding fine.

thats what I was wondering, if the probs were with the product or the prep... so cleaning the area well with a wire brush, rough it up with 80 grit, washing with soap and water, then say wipe it down with alcohol or maybe acetone, then it should work?

If your going to do it the cheep way. Wash it down sand it clean it again. Water and wipe down. Spray it with eather b/c eather will obsord moister nad oils and then evaperate. I do not balive alcohal will obsorb moister. And use a plastic epoxy that will suport temps of 200F is posible.
