i think thats what i did before but it didnt cool enough... i hooked my passinger fan up to a 30 amp fuse to the battery and it came on high but it didnt stop the needle from raising i shut it down at 3/4 didnt get to red zone, but you guys are either gonna get mad at me or laugh at me... i read the owners manual and it says to only use orange coolant with no silicate, well i used silicate free green coolant. my neighbor has a gmc that is supposed to use orange coolant and he put green in it and started over heating, and then he flushed it and put orange back in and it didnt overheat... so im going to swich it over, but that wouldnt keep my fans from coming on.... so next time i get a day off im going to put the orange coolant and replace both temp sensors and hope it works
