this may sound daft but is there a certain way to bleed the water on the erst? my temp gauge goes right up straight after start up from cold and heaters are warm instantly...i have changed everything i can think of..everything is new that i can think of and been double checked to make sure..even checked the wiring to temp sensor in case it was earthing out somewhere...to bleed off i run car with header tank cap off till fan cuts in..do you peeps do it a different way or have any ideas what it could be or what i should check as i am assuming there is still an air lock..any help much appreciated as its doing my tits in now n want the car on the road after a very long wait...cheers
