Aluminum/Plastic radiator crimp seam leaks.

Has anyone ever tried tightening the metal crimps around the leak tighter with a vise-grip? Any long term luck? Thanks

Not the answer to your question but leaks or weeps? Mine weeps when the temperature changes.

Hopefully some day somebody will make a good radiator for us.

A very slow leak with drops forming.

No luck. I noticed mine doing what you speak of. I pinched them down when everything was cool. This worked for a couple months until the jeep started getting hot. Plastic busted by upper hose port.

Crimping the tabs down a bit on the original radiator on my '00 kept me from having to replace it for about a year, but it eventually had to be replaced anyway. So yes, it does work, but it's more of a short term solution to delay the inevitable.

The seams are chemically sealed, those crimps are not what actually seal it so it's leak-free. Once it starts leaking from the seams it's time to replace it since it's not far from coming completely undone.

For a replacement, I'd stick with another OE Mopar radiator. Few aftermarket radiators cool as well and store brands are junk. And don't see a radiator pushing 2 or 3 rows as an improvement. The number of rows in a radiator is no direct indication of its cooling capacity even though some try to make you think it is.

When you have a choice, buy American made.
