Hi,
your drivers manual will tell your tow rating. I think it is 5,000 or 7,000 lbs.
You can add the small (about 6x8) external tranny cooler and connect the engine cooler (if you have one in the other end cap) with factory parts.
I did this on a 95 Suburban K1500, even without towing anything.
You will need to exchange one tranny line with a longer one and get a short line going from the main radiator to the new small one in front of them all.
Also, please check if you have the engine oil cooler in the drivers side endcap of the radiator.
It may be plugged with 2 green plastic caps.
You can get a different oil filter flange from where you have 2 lines going to the front.
Take care, Eggert
