Just wondering about the efficiency of the stock (in radiator) oil coolers. When i installed the Dmax radiator, i had to install an external EOC because the DMax radiators have no oil cooler in them. I bought a B&M 24,000gvw oil cooler and installed it in the front of the stack, just below my tranny cooler, it gets a good flow of air from the lower section of the grill and from the factory cutouts in the bumper.......







Since I have no way to measure the temps of my oil, i was wondering if this B&M cooler is working as well as the ones in the radiators? Any thoughts? I kept the 1/2" I.D consistant, using 1/2" I.D oil lines and fittings so there is no flow restriction.

 

Its probably just like the trans cooler, after market ones are almost always better than factory ones.
IMHO

 

I would hope so too, i was just wondering if anyone could confirm it. What does our EOT's usually run?

 

My EOT is typically around 170-180F during highway cruising. (0w30 Mobil 1, using 5w30 its higher around 180-195F) After running the engine hard for a few minutes it will climb in excess of 220-240F.

For Reference, the oil temp in my C6, crusing it stays around 215F, granted airflow isnt a corvette's greatest attribute.

One of the things i would love to know, is what the Power Steering temperature on these trucks run at... I look at the tiny little cooler and just shake my head.

 

I would think you could put an electric temp sending unit right in the line and run a guage off it to get your EOT... then just mount it in the cab wherever. I am sure your setup will cool better than stock though.

 

Here is a great writeup about what is the most well thought out oil cooler solution I have seen.

The oil tanks in the rad are there to heat up the oil quickly as well as to cool. They dont work all that well.

 

Very cool (no pun intended), thanks EYE!

 

I have never seen mine over 200* since I installed my engine oil cooler, it usually sits around 180*, 190* in +100* weather.
