Alright, anyone who has been around for a while knows I have been having a nightmare of a time fixing my bird and now the latest problem. I finally got the coolant pressure problem fixed (someone didnt fully torque the heads down ). Now I am trying to fill the coolant system and am running into a problem. I have removed the vent plug filled the radiator, reinstalled the plug, put the cap on and start the car. I have been trying to get it up to operating temp, but I get worried because the upper hose feels like it is full of air and not fluid. The hose also gets very hard and when I shut the car off I can bleed a little air out of the plug the fluid comes out and the rad. is full. Am I just being overly paranoid due to past problems and should just let it run till she gets up to temp. or is there something else wrong?
