I have noticed that after my car cools down and the radiator fluid goes into the coolant overflow resevoir that it seems to be leaking from the top of the resevoir and dripping onto my driveway. The car is not overheating, so I think this is what must be happening. Is this common? What can I do?

This seems odd - the overflow tank empties as the car cools. Perhaps its coming from the radiator cap itself?

If its coming from the resivoir - the resivoir is not part of the sealed system - if it overflows, it will leak out.

too much anti-freeze in the system.
an air bubble in the system.
faulty radiator cap.

be careful. i've been going thrugh this as well.

eventually, too muuch fluid will seep out!

i'm running a Mugen high pressure cap. i'll throw the stock one back on to check it out again.
