Talk Morgan Forums Morgan Sports Cars Maintenance & Servicing Radiator Leak

I've heard a lot of good things about JB Weld - there's an amusing You tube video where a bloke cuts a chunk out of a cylinder head with a grinder, fixes it with JB Weld and gets the engine running!

I think it's both. It appears to stop the wing tops splaying. I've removed mine a couple of times and just refitted it with the wing position as the guide. I imagine the main flex is during use. It might be worth measuring the distance first to make sure it goes back exactly.

Before I remove the crossbar I mark the position of the nuts with a dab of white paint, I can then position it exactly as it came off on replacement.

+1 for JB Weld but never used it on a radiator, or for cylinder head repairs

OK, so here is the follow up. I found that the radiator had been repaired with epoxy in the past, so my idea of soldering the leak might be dead. I sealed the ports and put 5 psi on it, placing it in a tub of water. The leak was coming from behind the top mounting bracket. I decided the only course of action was to inject some epoxy in from both sides. Worked perfectly. The radiator is back in the car and as is well. I found that removing the grill made the job much easier.
