Jeep Radiator Problem, you too?

Just curious I had two Jeep TJs radiators start leaking this on two seperate TJs. Then, a guys at my work his Cherokee started leaking too. Anyone else just curious all three at the same time seems like a big coincidence. Have a good one!

The stock radiator is known to separate along the plastic end caps where the metal is crimped. Although I recently bought a replacement OEM style (knowing this will happen again. ) from a local radiator shop. I wasn't completely sold on getting an all metal radiator because I did read about problems with those as well. Chances are an all metal radiator would be better. But I'd rather just have to drive my new radiator to a local shop than ship it off in the case that it breaks.

The Jeep's radiator is a pretty easy replacement. That was my first repair I did on my own Jeep. Check out the writeup at Jeep TJ Web Site of Stu Olson - N7QJP

All brass radiators are junk also, IMO. In a TJ, those have problems with the core tubes seperating from the tanks...

Thinking about getting a CSF Radiator with aluminum core or maybe Ready-Rad radiator with aluminum core..... but I just thought it was crazy that all three jeeps started leaking. Maybe a jeep villain going around poking holes...lol

It's not just Jeeps. Scads of vehicles out there use aluminum cores clamped to plastic tanks. My F-350 (7.5) rad was leaking a few years ago, and I replaced it with an all-aluminum radiator, to the tune of six hundred bucks!

If you do go with an all-aluminum radiator, be aware that you MUST use distilled water in the coolant mix, after using distilled water to flush all the old coolant from the system.

It is very possible for tap-water mixed coolant to conduct electricity (usually because of a bad ground on the engine). Over time, the electrical current flowing through the coolant to ground will eat through the radiator, one molecule at a time. It's the same as electroplating, but in reverse... the molecules of aluminum are lifted from the inside of the radiator and are held in flux in the coolant. If the inside of your filler neck is dark gray or black, it's happening.

Distilled water does not conduct electricity, so using distilled water in your coolant mix effectively stops the electrolysis.

My same thinking. 10 years and 74k miles. If I get that out of the new radiator I'll be happy. Who knows if a rock will get to it before then

Im using a Visteon Core with Tig welded Aluminum tanks.
Using spring style washers to clamp it to the grill assembly.
I haven't had any issues since tossing the brass/copper assembly away. (it was only in for a little over a year & the mounts tore from the cores, I assume from vibration & bouncing around. It looked pretty ragged & was also leaking from a core.)

The Alu. one has been in it for 2 years & looks good as new.

If you go Alu. just make sure to use DI water & proper coolant.

The Alu. also offers better cooling efficiency.

Great info and ya I always use distilled water when flushing and filling.

My original radiator started leaking at under 50,000 miles, and the all metal replacement was leaking less than 30,000 miles later. My Jeep has just over 89,000 miles and I am on my third radiator.

Just out of curiosity, where did you get your all metal replacement? And do you think that one leaked b/c of flexing?
