Section 22: HEATING AND AIR CONDITIONING 

 

PA1593 

36

8.  CENTRAL HEATING SYSTEM 

As seen earlier in this section, the vehicle 
interior is pressurized by its Heating, Ventilation 
and Air Conditioning (HVAC) system. The 
vehicle interior should always be slightly 
pressurized to prevent cold and moisture from 
entering. Air flow and controls divide the vehicle 
into two areas: driver’s area and passenger’s 
area. 

The schematic of figure 36 shows the central 
heating system with its components. 

8.1 

DRAINING HEATING SYSTEM 

To drain the entire system, refer to Section 05, 

“Cooling

”. If only the driver’s or main heater core 

must be drained, refer to the following 
instructions. 

 

Draining Driver’s Heater Core 

1.  Stop engine and allow engine coolant to 

cool. 

2.  Locate the normally open water pneumatic 

valve on the ceiling of the spare wheel 
compartment (Fig. 37), move the pilot-
solenoid valve red tab to close the valve. 

 

FIGURE 37: CEILING OF THE SPARE WHEEL 
COMPARTMENT 

 

WARNING

 

Before proceeding with the following steps, 
check that coolant has cooled down. 

3.  Loosen hose clamp, install an appropriate 

container to recover coolant, and 
disconnect silicone hose from water 
solenoid valve. 

4.  From inside of vehicle, remove the two 

finishing panels in front of unit. Remove the 
three screws fixing the unit front panel. 
Open the manual vent located inside the 
HVAC unit, on the driver’s side (Fig. 38) to 
ensure an efficient draining. 

 

FIGURE 38: DRIVER'S HVAC UNIT 

 

Draining Main Heater Core 

1.  Stop engine and allow engine coolant to 

cool. 

2.  Close both heater line shutoff valves. 

On X Series vehicles

, the valves are located in 

the engine compartment. One is on the L.H. side 
of compartment in front of the radiator and the 
other valve is located under the radiator fan 
gearbox (Fig. 39).
