Ok I have bad contact in my radiator wire that is causing it to work and not work. I need to find where it is causing the bad contact. How do I remove the radiator to find the bad contact and also while I am at it flush the radiator fluid

EDIT: I JUST NEED TO REMOVE THE FAN MOTOR

 

Unplug the fan switch and undo the four bolts that hold your fan onto the radiator. You can take off the fan without removing the radiator.

 

It could also be the thermal switch or it's connector...
