[Duke92]

Hi guys after a week of the radiator fan switch has failed again this time it is burnt see the photos attached put a new one in again still got loads of air in the system how do I get all the air out?

They are supposed to be self bleeding, which engine is it?

As I said on your other post, is it air in the system or gases? You shouldn't still have an air lock

[Duke92]

It is a s series with no bleed screw

[Duke92]

It is definitely a air lock jeff

Only had a lot of air after fitting a new thermostat?

Hi guys drained the coolant again this morning put a new fan switch on refill it with fresh coolant spent most of the day with engine running and heater on full on warm setting I left the expansion tank cap off and squeezed all heater hoses and collant hoses fan kicking in after getting all air out car seems to be running better and cooling better when warm cross fingers it stays like this.

Hope do, if you have the engine ticking over then put coolant in with the heater on hot with the fan full on that should elevate most if not all the air in the system

Thanks for that tip Jeff I will try that next time I fill the coolant thanks for your help it is still working perfectly at the moment after driving it this afternoon .
