Q: How do you troubleshoot an overheating engine with non-functioning cooling fans?
A: To troubleshoot an overheating engine with non-functioning Radiator fans, begin by checking the fuses. If the fuses are fine, proceed to disconnect the electrical connector for each fan motor and apply battery voltage to them using a fused jumper wire. If a fan motor doesn't come on, it needs to be replaced. Locate the relays in the engine compartment fuse/relay box and test them. If all the fuses, motors, and relays are functional, inspect the wiring and connections to the fan motors. For the replacement process, begin by removing the front bumper cover and draining the engine coolant.
