These models are equipped with two cooling fans mounted side-by-side behind the radiator. The PCM (Powertrain Control Module-engine computer) and three relays are used to operate the fans at Low or High speeds depending on engine needs and other conditions. The fans are protected by fuses inside the engine compartment's fuse/relay box. If the engine is overheating and neither of the cooling fans operate, check the fuses for the fans. Locate the fuses in the engine compartment fuse/relay box. Remove the fuse(s) and check them for continuity. If the fuses test good, check each cooling fan motor by unplugging the fan motor electrical connector and applying battery power directly to the motor terminals with fused jumper wires. When done correctly, the fan should come on. If a fan motor doesn't work, replace the motor. If the fan motors are okay but are still not coming on when the engine gets hot, the fan relays might be defective. Locate the relays in the engine compartment's fuse/relay box. You can pull each relay out and test them individually. If the fuses, motors and relays are functional, check all wiring and connections to the fan motors. If no obvious problems are found, have the cooling fan system and circuit diagnosed by a dealer service department or repair shop with the proper diagnostic equipment. To replace the cooling fan, disconnect the cable from the negative battery terminal, then disconnect the cooling fan electrical connector. Partially drain the cooling system. Remove the upper radiator hose. Remove the cooling fan shroud assembly mounting fasteners. Remove the cooling fan assembly by pulling it straight up and out of the engine compartment. If you are replacing a motor, remove the fan blade mounting nut to separate it from the motor. Remove the mounting fasteners for the motor and separate it from the shroud assembly. Installation is the reverse of removal. Be sure to engage the bottom of the fan assembly with the plastic mounts that hold it to the bottom of the radiator.

Remove the air filter housing and, on certain models, the throttle body.
