How do you bleed the cooling system on a 2.9 crdi sorento?

To bleed the cooling system on a 2.9 CRDi Sorento, start with the engine off and allow it to cool. Locate the bleed valve, typically near the thermostat or on the radiator, and open it. Fill the coolant reservoir to the appropriate level, then start the engine with the heater set to maximum. As the engine warms up, air bubbles will escape through the bleed valve; close it once a steady stream of coolant flows. Finally, check the coolant level and top off if necessary.
