Electric fan's really do help the overheating problem. The only problem, It's one more electronic to fail when your in the middle of know where. No fan, no cooling, Big freakin problem. Also, a big issue is the type of fan's we need to run in our trucks here in AZ. If we want to keep up with cooling here for summer wheeling, you need a monstrous fan, which puts it REALLY close to your motor. Which then the fan could be eaten by the motor. We have already seen it happen to one. I'm really curious to see how this dual pass Rad works. If it works the way I hope it does then that will be the route I go for all my trucks. <img src="/forums/images/graemlins/kewl.gif" alt="" />
