Cooling System Airlock

[Guest wrampo]

I have an airlock in the cooling system and cannot fill the system properly. I have fitted new radiator new thermostat, flushed system, checked for blockages etc. etc. I left the rad cap off overnight three months ago, and in the morning i was able to fill the system with approx 8 litres of water. All fine till last week. I lost water because of a leak. cured leak but am unable again to fill system with enough water. I have even used one of the new vacuum fillers without total success.

you are going to have to remove one off the water pipes, simply undo one of the clips and pull it of, then top it up,

hope this helps

You have remembered to set the heater to "maximum", I hope........

you need to get the engine warmed up and give it lots of revs with the system vented - not too hot, but warm enough to get the thermostat open. Rev the engine hard and keep topping up, thats worked for me on all cars.
