Evening all, I’ve been looking online for the correct way of bleeding air from the cooling system on a 2.5Na and can’t seem to find anything! Anyone know?

Fill the system through the rad plug. I found it was better if parked nose up hill a bit. Put heater control to hot. Run engine and top up as needed. If heater now starts to warm up you can be pretty sure all air gone. Replace rad plug and check expansion tank about half full.

Many thanks, did it last night and it worked a treat. Nice one!
