    • Flimsy handle.
Release handle feels flimsy. I think of I pulled on it the wrong way it would snap off with little effort. For the price its fine but not high quality.

    • Easy Installation, but durability might fade
Fits my Jeep Wrangler 3.6L cap perfectly, however I do think after a while the material will deteriorate after a lot of use. For the price and the convenience I will just replace again with the same. Otherwise I'm perfectly happy that nothing leaks from the cap.

    • Good radiator cap with a safety lever
This is an edited appraisal of the Moto rad radiator cap that has a level to release pressure. This is on a 03 PT cruiser turbo. I initially thought my problem was from the radiator cap that did not function properly. It turns out the radiator cap functions perfectly normal. There is a rubber hose that is attached to the metal waterlines on the side of the motor. I found that the rubber hose blue from old age from you know, heat and age I replaced that and haven’t had a problem since ironically I bought a different radiator cap that didn’t have the lever on it and it is in fact made by the same company motor rad so both caps function fine and I don’t have a problem with this lever radiator cap. I left a totally lousy review of this radiator cap a rather emotional review which turned out to be not correct and I do apologize to the company for that appraisal ... show more
