Fits and works great on a 2000 accord radiator.

Finally the proper button and spring size that would seat properly into my radiator. Not sure why this only promotes as being for Honda but this is the only one that actually fit my Lexus RX300. Skip all the other ones that allegedly fit and get this one. I'm not even upset the price went down after I bought it...

Well, my radiator lasted exactly 20 years before the plastic tank finally cracked. As a result, I replaced the radiator and it was the right time to replace the cap too. 20 years of wear and tear on a rubber seal and spring. When I saw this cap I knew it was the one to order. It looks identical to my original OEM one. The material, the underside where the rubber gaskets are and even the label. I has worked perfectly. It opens when the radiator is hot so the coolant can move to the tank and then lets the coolant back in as the radiator cools. Save money and buy this one instead of an OEM one.

It looks like a non-original product as it is. The quality is not there, but I guess it is a decent replacement for half price as long as it proves to be reliable, but only time will tell. Unfortunately if it fails or doesn’t operate as expected it could cause more serious issues with the engine, so I’d be cautious.

If your car has a problem with overheating and coolant leaking from the reservoir start with the radiator cap, if the cap is damaged or broken it will not keep the coolant system pressurized.

Not much to say other than it works, fits, as described and expected! The one I had was just fine but since I had replaced my radiator it was suggested I also get a new cap to go along with it, so I did. No issues whatsoever, fast shipping. Thank you!

A la semana de uso al revisar los niveles del radiador el tapón se quebró de la parte del resorte y empaques desprendiéndose de la tapa, muy mala calidad
