Diesel cooling options and ideas

[OrangeCJ]

Just had a quick, maybe dumb question, that may have been posted earlier...

I am adding an external cooler, similar to the BPD/Primer Gray setup... Basically you just pull the line off the oil cooler, connect it to the new external radiator and then route the output back to the cooler... correct? I read the instructions from BPD, but in my mind, I am missing something.

Yes, that's it. pre/post (can't remember which line goes through the aux cooler first) cool water that is superheated from transferring heat from the oil.

So another question for all you smart forum guys and gals...

Because of my bumper I have a bit more space, and I was thinking about going with this radiator as opposed to the inverter cooler.

The fitting size on the radiator is 7/8" which means I will have to step down the hose to match the 5/8 hose in the vehicle... Any thought on adverse affects by changing the inlet / outlet size?

This radiator seems to have a lot more surface area, and is totally aluminum, and fits the cutout in my skidplate almost perfectly, so there are some upsides... just want to make sure there are no downsides.

The factory oil cooler has coolant flowing through it. No matter what you do that becomes a heater once coolant temps go up to 225-230. You could have a giant oil cooler in the bed with dual fans and it will struggle to overcome this interconnect....

Lowering coolant temps to 195-210 will drop oil temps as your engines cooler all around.

I can fully control my temps by simply engaging the tazers cooldown function. Its been working A+
