5. When the engine is cool, drain the engine coolant from the radiator (see COOLANT CHECK ).

6. Slide the hose clamps (A) back, then disconnect the inlet heater hose (B) and the outlet heater hose (C)

from the heater core. Engine coolant will run out when the hoses are disconnected; drain it into a clean
drip pan. Be sure not to let engine coolant spill on the electrical parts or the painted surfaces. If any
coolant spills, rinse it off immediately.

Refill the cooling system with engine coolant (see COOLANT CHECK ).



Be sure to connect the drain hose securely.



Adjust the heater valve cable (see HEATER VALVE CABLE ADJUSTMENT ).



Make sure that there is no engine coolant leakage.



Make sure that there is no air leakage.



With air conditioning, refer to evaporator core replacement (see EVAPORATOR CORE
REPLACEMENT ).



Enter the anti-theft codes for the audio system, then enter the audio presets.
