Right today I checked all the wires and great they are ok. So I unplugged the temp switch on the bottom of the rad and plugged it into my old temp switch and held a lighter on it and after 20 seconds the fan came on so at least all the wires are good. I plugged it back into the fitted switch and run the car again it got half way on the dial (inside the car) and still the fans arnt working I felt the radiator the top half is red hot and the bottom is cold so did a flush it make sure theres no air lock and run again still just warn at the bottom of the rad. Do you guys think I need a new radiator
