Drain the engine coolant (see page 10-6). Remove the expansion tank hoses, then remove the expansion tank. Install the expansion tank in the reverse order of removal. Refill the radiator with engine coolant and bleed air from the cooling system with the heater valve open (see page 10-6).

Disconnect the 2P connectors from the radiator fan motor and condenser fan motor. Test the motor by connecting battery power to the B terminal and ground to the A terminal. If the motor fails to run or does not run smoothly, replace it. aaa
