Does anyone know where to get the small o-ring that goes on the small metal pipe when changing the water neck on a 2.4l? I have the big o-ring that's the actual water neck gasket, but I tore the small one that goes on the metal pipe that goes to the reservoir. Has anyone had this problem and if so, were you able to find a new one or were you able to find another fix?
I bought a new one from my Chevy dealer when I bought a new water neck after my old one started leaking. When I inserted the metal pipe I put a little Loctite gasket maker on the oring to help it seal well.
I was sure the little pipe and o-ring would leak because it doesn't seem to be a positive and secure method to seal the radiator pressure. But to my surprise it works just fine.
BTW, if you have to replace the plastic radiator neck don't use a cheap Chinese after market one from Autozone or PartsAmerica. I did and it cracked within days and leaked all over the place. I replaced the Chincrap one with a GM part and haven't had one lick of a problem.
I wish the oem was metal though.
Couldn't find it at the parts stores, but I just got one from the dealer. $2.03
