Outer Limits 4x4 Board

Hi fellas. I have just about had enough of my overheating rangie. It hasn't been right since that electric fan fiasco, you know Sam, the ones I gave you for your buggy? I can drive around fine until I get up to highway speed for any length of time or labour the engine on a hill. It doesn't make any difference if I have the 33's or the 35's on. Are the four core radiators that much better? The other thing is the CV's. I spoke to Mal Story the other day and he is talking about some that are under going feild testing in th US. I hope they work out because I am getting pretty sick of chewing them to bits with seemingly little effort. Any thoughts would be apreciated.
