to make it look alot cleaner and elinate the clutch fan being at fault u could always just wire up the a/c condensor fan, thats what i did i got rid of the clutch fan, wired up the electric fan, and removed the fan shrowd mine doesn't go past the half way mark and it makes the engine bay look much cleaner, i'd say try flushing your coolant system, and make sure ur installing the thermostat the right way....

have you tried checking ur coolant level? Just checking.

Try bleeding your cooling system. It is a real common problem on the KA and is a ***** to find. You just pull the radiator cap, and then remove that little screw on the hose barb on the intake mani, in front of cyl 1. Fill the coolant until coolant comes out of there. Then jump on the front of the car until the coolant level falls a little and do it again. Then drive around and get it hot, remove the cap (BE CAREFUL!!!!!!!!), and then that screw (again, BE CAREFUL!!!!) add coolant until it comes out again. Do you have the problem after you do that?
