Coolant Leaking Again

[a_alyte]

'98 JGC

I had this same issue back in '05, coolant leaking from passenger side. When I pop the hood the coolant can be seen puddling just below the drain plug on the radiator, but the drain plug is tight & dry. All hose clamps are tight. When the Jeep is turned off, the coolant drips off the front bumper causing the reservoir to get low after a couple weeks . In '05 I replaced the rad, thermostat, water pump & hoses. It was good for a while but here I am again with the same issue.

Anyone dealing/dealt with this?

I am. I don't have any idea where the leak is, but it's very slow so I havn't put much time into it just because I plan on doing a swap soon when I put the electric fan in.

Hope someone can help ya.

Use a pressure tester to pressurize the radiator and look for the leak.

It is probably leaking from the seam where the radiator core and side tanks meet.
I had this problem with a couple radiator along with the new one I just replaced back in march, getting ready to send it back for a new one under warranty

If my leak is coming from the seam as you described, is there something that can be moved or bent out of the way when installing a new rad to prevent it from reoccurring?

I don't know what you could do better other than be reasonably careful - when it's in the vehicle it takes a pretty good pounding.
As dksob81 said, the side seams are where they usually leak, but I cant believe you guys are having such bad luck. Are they OEM or aftermarket?

The 1st one I put in was OEM & the one leaking now is aftermarket. In my Jeep they seem to leak every 2 yrs.
