Coolant\radiator question.
Just got my 98 C5 and noticed that when the engine is off the main radiator
hose is flat,with the air sucked out of it.When I unscrew the radiator fluid
cap it goes back to normal,or of course when I start the car.It seems I have
a little air in the radiator system.Is this normal? And without flushing the
system is there anything I can do to remove the air? The coolant looks fine.
Thank's.

Re: Coolant\radiator question. (bhamvett)
I have a 98 Coupe also. I had the same problem. Change the cap. Go to your local GM parts department and get a cap for a 2002 Corvette. It's the same part number, but it's a different cap. Check out the underside of the cap, the new cap is 18 psi pressure, the old one is 15 psi pressure.
Part number 25713160. Haven't had a problem since.
