i did the same ..but i have could air sometimes on the drivers side air vent ,( fine on the other vents passenger side and rear cabin vents) then it will go luke warm on the drivers side sometimes which i am sure is being caused by a small airlock.

anyone else confirm the car dont have a bleed valve

regards

PS thanks for the reply
