Alright guys, I've looked around and seen some here and there, but considering the importance of a cool running truck, I figured it might be a good idea to get everyone's cooling tips (engine, trans, etc.) together in one place. Most people already know a few, like a trans cooler, low temp t-stat. But I know some of you have got some cooling tips that would help a lot. So list what ya got! Thanks for the help.

 

an electric fan, I noticed 5-10 degree cooler running with my K&N FIPK, coolant flush (if never done so. I noticed a huge difference in temp when I did mine the first time).

 

doesnt affect engine temp but... fuel cooler... gained 6% in fuel mileage (risky though... do it at your own risk)
inuslated fuel rails.

 

How do you insulate your fuel rails? As long as mine are out of the truck it would be a good time to wrap them.
