Why does is my overflow tank empty
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.
Thanks...will try that this evening.
