Planning to replace the radiator on my 05 H2 myself. Due to a little transmission fluid keep leaking under the radiator. I replaced transmission oil cooler, checked all hoses and connections everything look fine with no sign to oil drip or leaking. But still see transmission fluid keep leaking under the radiator, So I think is it the radiator problem. Any hints, tips or instructions of how to replace the radiator would be greatly appreciates.

 

If the only problem is leaking ATF. Leave the radiator alone and completely bypass the radiator transmission cooler.

 

How, and do i have to get a bigger atf cooler for this mod? Thanks

 

you don't have to get a bigger one although most of us doing this mod did, where the tranny lines go into the radiator cooler disconnect them from radiator and run them directly to a separate tranny cooler completely eliminating where they go into and out of radiator, most aftermarket tranny coolers come with hose and clamps etc, theres a small spring clip that holds lines onto fittings going into radiator just pull the clips and then pull lines right out of fittings in radiator, add hose run to cooler

 

Can i run them directly into the manufacture atf cooler mounted in the front of the vehicle, or do I have to get a extra aftermarket atf cooler?

 

you can use factory one if you want, I don't remember how big or small it is but bypassing the radiator one is a very good idea, pay attention to tranny fluid temp guage if its to warm for your liking buy an aftermarket one then, by he way aftermarket ones from places like summit or even some parts stores aren't very expensive even if you buy one twice as big as factory theres many many sizes to pick from
