Oil cooler

On 05 cm870 475hp cpl 8519 does anyone know how many cooling units are in the oil cooler? I thought there was two separate units one on each side but ive heard it may depend on hp rating. Maybe higher hp rated engines only have two idk?? Anybody????

It seems to me that it was hit and miss with them but maybe someone else knows more detail.

Either case, I have never seen the single element oil cooler not be able to keep up on one, even at 600+ HP.

If you have excess oil temp issues, then it is most likely something wrong.

My theory is that it was not HP related but CPL and manufacturer truck model related. Or rather a combination.. ie above a certain HP on a truck with poor airflow you would see one.. then eventually they changed the material the element was made out of and stuck with mostly 1 element. You can enter your ESN into quickserve lookup your oil cooler in the parts catalog portion of your engine and it should specify how many elements were built in that engine. Quickserve is free to register up to 5 engines and very nice to have.

Dual element housings are no longer available, just an FYI.

You mentioned poor air flow. Iyo would a truck with a high hp rating and very poor air flow cause problems with high oil temps?
