If Im going to bypas the internal cooler?

gary's theory, which i agree with, is that your stock cooler can actually become a "warmer", as the radiator is going to be warmed by the water.... i'd say that if you are externally cooled, bypass the radiator cooler..

You might try what I did. I found a spot in front of the radiator to mount the cooler, measured the space and bought the biggest cooler that NAPA sold. It is mounted right next to the A/C condenser.

Steve,

Run the biggest damn cooler you can physically fit in there. I have a

26,500# GVW Hayden Ultracool installed on my 88' C1500.

Won't this cause problems in the winter when outside temps are in the teens? I would think in the winter you would want the fluid warmed by the radiator coolant.

Opinions?

It warms itself up just fine as soon as the TC starts doing its thing. I run around 100* in the winter with a Hayden Ultra-Cool 26,500# cooler, bypassing the OE cooler. 88' C1500.
