Hello all, been awhile since my last post.
I recently drained and filled my radiator and am having trouble filling the radiator fully. My overflow is three quarters full but there is room at the top of the radiator. If I try to draw fluid out of overflow to put into the radiator it seems to drain right back into the overflow and never fill the top of the radiator (it is not flowing through the overflow at the top of the rad). Is there any trick to get the air out of top of the radiator? Thanks.
