Steps
Park on level ground and let the engine cool completely, at least two hours. Never open the expansion tank cap while the engine is warm, because the coolant is scalding.
Open the expansion tank cap slowly to release any pressure, then fill with a 50/50 mix of the specified coolant and distilled water up to the max mark.
Find the bleed screw on the heater hose or thermostat housing. Open it a couple of turns with an 8mm socket, but do not remove it.
Set the cabin heater to maximum hot and the fan to its lowest speed so coolant flows through the heater core.
Start the engine and let it idle. Watch the bleed screw, and close it once a steady stream of coolant with no bubbles comes out.
Hold the engine at about 2000 rpm for two to three minutes and squeeze the radiator hoses a few times to push trapped air toward the bleed point.
Open the bleed screw again briefly to release any remaining air, then top the expansion tank back up to the max mark.
Watch the temperature gauge and the heater output. Repeat the open, bleed and top-up cycle until the heater blows hot and no bubbles appear.
Switch off, let the engine cool, then check the level and top up to max if it has dropped. Refit the cap firmly.
Tips and common mistakes
A vacuum filler pulls the air out before you add coolant and saves most of the bleeding work if you have one.
Use only the coolant type specified for the Velar, since mixing types can clog the system.
A heater that stays cold and a gauge that keeps climbing are the usual signs that air is still trapped.
Some Velar models need a service bleed routine run through a diagnostic tool to cycle the electric coolant pump.
Questions
How do I know if there is air in the cooling system?
The heater blows cold, you hear gurgling behind the dash, and the temperature gauge rises and drops. Bleeding again and topping up usually fixes it.
Can I drive with air still in the system?
No. Trapped air can stop coolant reaching the engine and cause overheating, so keep bleeding until the heater is hot and the level stays steady.
Do I have to use a scan tool?
Not always. Many Velars bleed fine with the screw and heater method, but some need a diagnostic tool to run the pump bleed routine.
