First, I well-understand and accept the consensus that Fieros should run NON-vented 16lbs caps on the radiator.
Nevertheless, for giggles this am I decided to look closely at my radiator cap and discovered the word "VENTED" stamped into it. Huh? This car runs cool and never drains coolant into the overflow tank or onto the floor when parked and left overnight. Still, as the radiator cap in a Fiero is not the highest point in the cooling system, gravity should cause fluid to leak past the vented cap and into the overflow tank. How is this not happening in my car?
BTW I've got a 4.9 in it, but that shouldn't matter.
