Hi. Can anybody hep me. I thought I had a radiator bockage and have now boughta new rad only to find the old one was okay but I have air in the system. The car runs happily all day upto 40mph (upto 1800 revs) but then overheats. Is there a secret in bleeding air out the system. When I talk people say its a tricky job on a LS400.
My car is a 93 LS400.
Please, somebody help?
