Hi lads I have to change the radiator hoses this weekend as they are getting very perished. Going to do top and bottom hoses. I have a 2001 classic turbo gf8. When i'm bleeding the air out of the rad afterwards should I have the heating on/off or on hot/cold. Also how long should I leave the car running and at what RPM. Thanks for any advice..
 
I always bleed with the heating on hot and if you can lift the front of the car sometimes it helps get all the air out of the system"hope this helps.
