Cooling System Draining, Filling And Bleeding (page 3 of 3)

 
15 .  Fill the cooling system to the upper level mark of the expansion tank.  
 
 
16 .  Start and run the engine.  

 
 
17 .  Fill the cooling system, keeping coolant to the upper level mark of the expansion tank until a steady stream of 
coolant is seen returning to the expansion tank. Tighten the bleed screw.  
 
 
18 .  Install the coolant expansion tank cap.  
 

 
19 .  Run the engine until the thermostat opens.  
 
 
20 .  Check the heater for correct operation.  
 
 
21 .  Switch the engine off and allow to cool.  
 
 
22 .  Install the engine cover.  

Engine Cover - 4.0L (12.30.50)

 
 
23 .  Clean any remaining coolant from the chassis and surrounding area.  
 
 
24 .  Install the radiator access panel.  

 
 
25 .  Install the front LH splash shield.  
 
 
26 .  NOTE :  

 
Check and top-up the coolant if required.  
 
 

Hold the engine speed at 2,500 RPM for 30 seconds.

Return the engine to idle for 30 seconds.

Repeat the above procedure a further four times.

Tighten the 4 bolts to 10 Nm (7 lb.ft).

When the cooling system is warm, the coolant will be approximately 30mm above the upper level mark on the 
expansion tank with the cap fitted.
