I recently replaced my Toyota radiator cap with a genuine part that fits perfectly. The original cap lasted 12 years and was still functioning, but I opted for a replacement as part of preventative maintenance. The new cap looks identical to the original. Looking forward to seeing how long this one lasts!

I had a small coolant leak develop in my 1998 (22 year old) Camry and determined it was most likely a bad radiator cap that was not properly releasing pressure and allowing coolant to go back to the reservoir when the car warmed up, but rather was over-pressuring the system and forcing a leak at the hose connections. This new one is a genuine original equipement replacent. I put it on. No more leaks. I had also read to be careful about aftermarket radiator caps - so didn't take a chance. For a few extra dollars it's a lot better than having some more expensive repair when it fails.

I don’t know if this is a OEM product but it looks good quality. Hopefully it’ll last long that yellow sticker was on top of the white one, so they might be OEM who knows.

I purchased a new radiator cap for my 1999 Toyota 4runner when I replaced my old radiator unit for a new one. It turns out my new radiator cap was a aftermarket knock-off which I assume was OEM. After two months the aftermarket cap label(Pictured Left) started to warp & peel off the cap. I decided to buy a genuine Denso OEM radiator cap to have the peace of mind that it will work properly & not fail. The OEM radiator cap(Pictured Right) has better quality feel to it. It also has two engraved D's on the side stamped by Denso & the aftermarket has no engravings. Overall I recommend buying OEM knowing the part will last a long time.

2000 camry sprung a bad radiator leak while on vacation. Found the nearest local auto service and got it replaced. They swapped out the cap also. Everything was fine the first few days. But then I noticed a small hairline leak. I thought it was coming from the radiator. So I wiped it clean and checked a day or two later, same thing. But I could not tell exactly where it was coming from but thought for sure it was the radiator itself.Called to get it replaced. They gave me all the info on where to go.. In the mean time I was still wiping the radiator and trying to pinpoint itssource. Again thought for certain it was coming from the top side but not the cap itself. Did some research and found others puzzled until they swapped with a new OEM cap. Our local stores did not have the OEM but they did have an aftermarket with OEM pressure specs.Bought that one with no luck. After a few minutes driving this leak was worse than with the other cap and I could clearly see it was coming from the cap. I quckly put the old one back on fired up the laptop and went on Amazon to buy the OEM cap. It arrived a few days later and I anxiously installed it to see if it held up to its rave reviews,I popped the hood after several minutes driving and to my pleasant surprise there were no leaks. Waited a few days before I was satisfied that the capactually was keeping pressure. A few days later still no leak. GET THIS OEM PART!!! IT WORKS!!!

aftermarket cap was opening the bypass valve at a lower pressure, oem cap solved that and the overflowing rez issues
