Range Rover L322 4.4 V8 petrol (BMW): coolant change (10-year)
Cooling · Range Rover L322 (2002–12) · 2002–2005
How often: every 10 yrs. Land Rover renews the coolant every 10 years regardless of mileage. Check the level and strength every service.
Coolant
Antifreeze to Land Rover / BMW spec
Work safely: support the vehicle on axle stands, never a jack alone; let it cool first. Check figures against your workshop manual. You do this work at your own risk.
Parts
Antifreeze concentrate (Antifreeze to Land Rover / BMW spec)
Hoses & clips (if needed) (replace any soft, swollen or cracked hoses)
Tools
Drain tray
Garden hose
Screwdrivers
Hydrometer or refractometer
Step by step
Work on a cold engine only. Remove the expansion tank or radiator cap slowly.
Open the radiator drain (or remove the bottom hose) and the cylinder block drain tap or plug. Set the heater to hot.
Flush with clean water until it runs clear. Squeeze every hose: replace any that feel soft, crunchy or swollen.
Check the radiator fins, fan blades and (where fitted) the viscous coupling. A viscous fan should turn with some resistance when the engine is warm.
Refill with a 50% antifreeze mix (Antifreeze to Land Rover / BMW spec). Fill slowly to avoid air locks; on coil-sprung models use the bleed screw on the thermostat housing or radiator top where fitted.
Run the engine to working temperature with the cap off (or loose), top up as the level drops, refit the cap and check again when cold.
