I was thinking about an aux oil cooler. Getting ready for some heavy towing this summer. I'm running that FS2500 bypass oil cooler that taps into the block's pressure port back of the regular oil cooler. Could this be tapped into to supply a aux cooler. MadVan Bill, how did you do yours??

 

My setup is an adapter on the block.
From the adapter i feed the cooler and
remote oil filter. The oil cooler has a 180*
t-stat on it to bypass the cooler. I had the
cooler mounted in the grill but removed it.
The ac system suffered from the oil cooler.
Its been mounted under the truck for years now with a fan.

Cool, (lol), where under the truck did you mount it? How big of cooler are you using? A fan sounds good! Just running empty the other day my oil, according to the new scan guage, was 220*. My trans temp was 200", I'm going to take off that thermostat, I'm tired of that thing making my trans run hot. It will run 160-170* without it. Unless, and I've been thinking this for years, replacing the trans lines to the bigger size along with the hoses to the cooler. I can't remmember the sizes of stock and the next size up?

 

Stock Lines: 5/16" to 3/8"
That is what I went to when I did mine.

Rog, did it help with cooling, in other words, did it get the oil up and back from the coolers better? I suppose you need adapters on the trans for the 3/8"?
