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.

3. Set the temperature control dial on Max Cool with the ignition switch ON (II).  

4. Attach the heater valve cable to the air mix control linkage as shown in step 2. Hold the end of the heater 

valve cable housing against the stop (D), then snap the heater valve cable housing into the cable clamp.  

5. From under the hood, turn the heater valve arm (A) to the fully closed position as shown, and hold it.
