Why does is my overflow tank empty

Asked by migration_Tina2383 Oct 09, 2014 at 10:02 AM about the 2002 GMC Envoy 4 Dr SLE 4WD SUV

Question type: Maintenance & Repair

I had my radiator and coolant overflow tank replaced and my radiator is full with coolant but my overflow tank remains empty.  I can't see any leaks but I don't understand why coolant isn't returning to the overflow tank when the car cools down.  The car doesn't overheat so is this a problem?

Try replacing the radiator cap with a name brand one. See if that helps.
