My truck has left me on the side of the road three times due to cooling system fails (water pump, coolant pressure tank, and now what we assume to be the radiator in the way to PA). Needless to say I am fed up with the closed loop system (even though it wasn’t at fault the first time). I am going to convert the truck to open loop, but I am interested in hearing about upgrades along the way. What are the thoughts on high flow water pumps, different fans (electric or different mechanical fans), and upgraded radiators. The Mishimoto looks nice, but no $425 nice.
