The be all end all radiator

There is a MOPAR Extreme Duty radiator for the XJ. It is made for ME export. I have run the Evans coolant. The temps will be higher. Evans told me that more heat is being removed.

Even the Mopar Middle East radiator was only a 2 core 1.5” thick (2x3/4” cores). The Novak is 3” core with no tranny cooler provision. I’m just not sure you could get the condenser in place. Interesting info on the Evans. So basically if you runs Evans coolant you need more radiator capacity it sounds like.

Not to my knowledge. The coolant just transfers the heat better. In my application, a '75 Bricklin, I noticed temps went up when going over 55 mph. Yes, back in them days. Then went down after 1/2 hour at 55 mph. I use ZO-5 coolant in my XJs. Supposedly you can mix it at 75% for extreme heat. I have not tired it. I run about 208 F and might peak to 215 F.  I'm in the Mid West so not an extreme environment.

I'm running a Mishimoto all aluminum radiator.  It's massive.  Can't see anything doing better than that.

A thread I was involved in, the guy was in AZ. I remember he had one of the early Mishimoto's. It reduced his temps a lot. I asked what his previous rad was. It was a HD MOPAR.

I would like to hear more about this radiator.

The old Griffin Jeep Speed radiator was a 3” core. The only thing similar nowadays that I’ve come across is the Novak. The Jeep speed crowd would probably have more info on options.
