I've been blowing into my expansion tank for about 10 minutes and the top hose from the radiator is still hissing air.
Really wish i had a valve built into an expansion cap top about now.
The top hose gets hot, but the radiator isn't hot, just on the left hand side a little.
Should it really take this long to get rid of, or is there something else amiss. I don't want to spend another 10minutes giving it face only to find out my efforts are futile.
Anyone?
