External engine oil cooler 2007 780 w/ 2006 isx

Here is something that I'm thinking about doing and would like advice from the people that know.

I would like to run my engine oil into the external, ratiator, oil cooler after it's passed through the bypass filter.

Here's my question: the 780 Volvo with the isx and the automatic tranny-does it use the radiator, to cool he tranny oil, that has antifreeze running through or; does it use it's own exteranal/dedicated radiator.

If it uses the regular antifreeze radiator, I might be able to replace my radiator With the radiator that was meant to cool the tranny oil and run the engine oil in it, instead.

If the truck has it's own radiator then, I might use that.

Part numbers and good places to buy would be appreciated.

Thank you.

 

That's great. All I need is to buy a used rad. Made for the truck with the auto tranny, take my out, install that one, and plum the lines for the engine oil. I want to lower the temp of the engine oil, the cooler it is the better.

 

If I can send oil to radiator then back to the pan. I might be able to run cooler. Don't tell me that you would like to run with the oil
Closer to 200*f vs 150*f.

 

I have the cummins isx. I want to try and be able to run below 200*f on the hot summer day on the 6% and higher hills, loaded.

 

Because ? Why would not want cooler oil?
