I've recently solved an overdrive issue by changing my radiator. Great, but now I've got trapped air and thus a cold heater??? I've tried having the front elevated on ramps with the rad cap off and a the heater on hot with the fan off to let it purge air. last night I had it like this for 45 mins and whilst some bubbles did come out I've still got stone cold air from the vents........HELP, What am I doing wrong?
Any advice/replies appreciated.
