Mike how right you are on this point.

My radiator is just a factory 3 core, which was bought new to replace the old one, but not by me. When I got the truck, the guy told me he installed a new radiator. I pretty soon found out why he had to. The owner before him never knew what changing antifreeze meant. Anyway, when I replaced the 305, I had the radiator rodded out to like new condition.

I run a Stewart Components Stage 2 aluminum water pump. This is all the upgrading I've done to my cooling system, besides my dual 14" Spal fans. Of course I have a wired in temp switch that kicks my fans on at 210, and off at 180. But, they will only come on, like I said after running at idle for a few minutes. I have never had them come on while driving.
