Radiator leak seems to be at the bottom left corner on passenger side. I can't see where it is leaking (cramped in there). Is there a hose or clamp that I cant see? Radiator is not very old, less than three years old. Thank you in advance for any input.
This is my first post, I hope I am doing it right....

 

Welcome to the forum.

Leaking at these corners is not uncommon, especially in OEM style radiators that have plastic in them.

I'd get it up on a hoist if you can, then be absolutely sure that you have ruled out any hose leaks.

If it is the radiator, you might want to consider an all metal radiator upgrade.

Radiatorbarn.com is a good source for them. The upgrade really isn't that expensive.

 

Yea deff a good idea to upgrade to he 3-core all metal radiator from Radiatorbarn.com
I have done this upgrade to 2 of my former XJ's and loved it. They run about $170. As for your leak, the stock radiator has plastic sides and they tend to leak. DO NOT get any of the stop leak crap. That will just add to the list of parts to replace when it clogs up the rest of your cooling equipment. If the leak isnt too bad just keep coolant in it to prevent it from overheating. Once the overheat, you can say hello to a host of overheating issues. The XJ cylinder heads are VERY sensitive to overheating and will warp quicker than you can blink. Good Luck!!

 

Thank you, guys, I will try and look at it today.
I appreciate the help.

 

Lower passenger side of the radiator has the "drain" make sure it's closed.

 

My radiator is Leaking from that same corner, I have inspected all hoses and they check out to be good. Also I check that little drain valve and the plastic piece is pointing up so I'm sure its closed. I checked with a light underneath and i touch the wire loom that's next to it and its wet with radiator fluid. So i have no idea if its the radiator that's leaking. I'm looking on http://radiatorbarn.com/search.php?product=radiator, at the metal one and i just want to make sure if it will fit Correctly with no Customizations?
