Bought and installed on my 2000 Saturn SW2 after breaking my OEM one. Fits great. Does the job. No leaks. And I prefer this one because I can open the drain by hand now, without a ratchet or hex wrench like the OEM one.

It's ay easier to use than the OE part thanks to the handle.

My stock one broke when removing it and this seems to help. My stock plug also didn’t have the ‘wings’ to install by hand. This fit well and seems to be leak free!

Bought new radiator from oriellys, already has this installed. HOWEVER if keeping yours (mine leaked through blades) this is a great product. -2 for Oriellys already having this.

Worked in my 96 Impala SS, if you still have the stock radiator in this plug will work. It looks bigger than it actually is, in the photo.

Perfect fit on 1999 K1500 Suburban. The old one had been broken so that you couldn't get a grip on it to turn it, which made draining the radiator impossible without removing hoses. I bought some special long handle pliers to get a grip on the edges of the old drain cock. After some work, I finally got the old one out. This new one went in with ease and turned closed and open with no problems. I can reach up from underneath with one hand and easily drain the radiator now.

The form of this plug is MUCH better than the original with only a square hole to turn. The original was awful. But be aware, this is only for an OEM style radiator. I eventually bought a replacement radiator and this did not fit it.

Slotted right into the radiator on my ‘02 Malibu without a hitch. No leaks. Infinitely less fussy than the OEM design. It’s all I could want.

This was cheap enough, I just got it as a spare for my C5 Corvette. I have an AC Delco one in it currently, but I'll keep this in my garage just in case I snap it next time I drain my cooling system like I did last time, lol.

The original GM one is a pain in the bottom to take off when draining and changing the coolant. This plug is much better designed and makes the job much easier.
