OEM product. Arrived quickly and fit perfectly. I however during the bleeding process opened the cap too soon and it of course....sprayed coolant everywhere. I sat the radiator cap off to the side and then heard the pop and the pressure seal popped out. I was able to replace it and I believe that is normal and what it was supposed to do. However, I ran to the local automotive store and bought and aftermarket cap. It is doing the job. I am still working on the car so It still overheats (water pump), but this cap fixed the problem of the disappearing coolant without leaks! I will have it as a backup and once I confirm it is okay to use after it snapped. I will actually put this back on and keep the aftermarket as a backup. They are cheap enough cost wise. My original cap lasted 186K miles!

It fit and worked for 1 year then fell apart and failed. The result was catastrophic. My 18 year old does not know any better.... started losing fluid, which over heated the car and destroyed the raidiator, water pump, thermostat housing.... any way $$$ later. All because of a cheap cap. lesson learned

First time they sent me a faulty one that didn't even hold. Second one now working well. I've had it for a couple of months now and everything is great so far.
