Rated 4.7 out of 5 by 3 reviewers.

Rated 5 out of 5 by Stant is good and reliable Geo Metro 1.0L radiator had consistently low coolant level, even with topping off daily. No outside leaks and no white smoke out the exhaust. Thought maybe the old radiator cap didn't seal properly, so the coolant was overflowing into the expansion tank when the engine gets hot, but not coming back into the radiator when the engine cools off. Could not notice level increase in the expansion tank (custom, bigger than stock). This new Stant radiator cap solved the problem. Fits perfect. Durability rating again based on previous purchases.
