    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
