Bleeding cooling system

Recommended Posts

I've got air in my cooling system.  I imagine its got something to do with the heater.  I've got standard Westfield header tank and heater mounted in the correct positions but mounted thus the heater pipes are above the level of the header tank.  Photos I took of cars at the factory seem to be the same.  Any ideas for how best to bleed it ?

Cheers

Hi Tomo. Good to hear you've passed SVA ;)

Try removing the header tank and have an assistant hold the header tank as high up as possible whilst you loosen the upper heater hose off to expel trapped air. When you remove the heater hose off the engine, blank the engine side off with your thumb etc to stem water flow and encourage water/air through the heater and out through the disconnected pipe. Try and keep the header tank topped up at the same time. When you are happy that all air is removed connect back up and fingers crossed it will do the job.

Good luck, Stu.

Thanks for the tips Stu.  Am I right in thinking that all this is happening whilst the engine is running ?  Or do you just crank it over slowly on the starter ?

Cheers
