Ron Davis makes one that should be drop in.

And Be Cool does as well.

Neither one is going to be cheap, but both are well made and will last a long long time.

This is what I had planned
Be cool 60102
@ $750
Not cheap but in the long run it is worth it

A radiator is one place you don't want to skimp. I also want a BeCool radiator.

Sorry to bring up an old thread but I will be replacing my radiator soon.

I know I want a beCool radiator but I wasn't sure which one. I've seen 67102, 62102, and 60102 referenced. So I called becool and it sounds like the only difference is how many coolers it comes with, if at all. So 67102 comes with oil and tranny cooler, 62102 comes with just a tranny cooler, and 60102 has no coolers. And they are priced accordingly.

I have already bypassed the tranny cooler in the stock radiator and added a larger tranny cooler. That solved the tranny heat issue while towing. So I think I want the 60102. But I never looked to see if we have oil lines running through the stock radiator.

I just checked, it looks like we have oil lines running through the driver's side of the radiator. So that means 67102 would be the correct becool radiator. Or I believe you can save a few bucks and get 66102 which is the same thing but not polished.

Just ordered the 66102 direct from Be Cool b/c they needed to provide an adapter for our oil lines that run through the radiator. I'll post some pictures of the install.

Looking forward to cool running while towing up those hills in the 110 heat out here.

Ron Davis Radiator
 

I purchased a Ron Davis radiator for my 2006 H2 which has been highly modified to produce 1100 HP at the wheels. The truck is kept in the garage most of the time and does not go off road. This radiator did not cool well with either stock fan or electrics, it’s just bigger than stock. With 2 Spal fans pushing and 2 fans pulling it could maintain 205 deg stopped with aircon on at 95 deg ambient for 3 minutes; after which the computer is set to switch it off to avoid overheating. At approximately 1500 miles of use the radiator began leaking. I pulled it out at 3000 miles and had it inspected. It had leaks at all 4 corners of the core and could not be repaired locally . I contacted Ron Davis regarding a warranty replacement and they politely rejected any responsibility after 90 days of use!!

Due to my engine modifications I cannot go back to stock. After considerable positive discussions, C&R Racing is building a custom R-Fin radiator for it now, due back to me at the end of December 2021. Will post performance results after installation.
