This radiator cap seems to work correctly and the lock does function as designed. The lock does feel a little cheap and flimsy though.

Not a big fan of this cap for a few reasons it doesn't seal or atleast have the same seal system as the ac delco one on the s-10 it also has two ears not four so there bigger then expected but it works with a lil common sense which if you use the advance radiator the overflow hose is a lil bigger then the rads nipple so buy a smaller hose clamp and pay attention to orientation of said clamp if using this rad cap

First cap we received came apart in two pieces after installing it. Second cap is doing better so far but still too early to tell if it will be a good long term solution.
