Preparing for a west cost road trip in a 05 Denali towing 7k.

We're going to Disney Land! From Washington ...Towing an RV.

Immediate problem is a cracked radiator. I want to put a larger radiator in, which appears to mean I need an external oil cooler. While I'm doing that sort of thing I want to upgrade the trans cooler as well and bypass some plumbing for both.

I've found some solid trans cooler kits, but no good oil cooler kits. Can I use the same thing for both?

Is there a good recommendation of a radiator that will fit my goals here?

To me it seems like a radiator from a one ton diesel or gas would work.. ?

Well I bought a larger trans cooler kit and a new standard 34" radiator. The plumbing of everything as it interacts with the radiator is confusing me... but I'll figure it out this weekend when I do the install.

I decided on no engine oil cooler as I don't think the juice is worth the squeeze.

You can use a tranny cooler for cooling your oil. If you are towing that heavy a trailer, the oil will get very hot.
