Radiator Overflow Hose Must be leaking! Where do I find a replacement part from? - Camaro5 Chevy Camaro Forum / Camaro ZL1, SS and V6 Forums

I have been dealing with my 2011 Chevrolet Camaro 2SS radiator overflow hose slowly leaking. For at least the last 4 months. The reason why is because I can not find a replacement part to resolve the problem. The part has been discontinued from the manufacturer GM.

2011 Camaro 2SS Overflow Hose - GM Part ID: 22756186 Discontinued.

Can anyone on the forum help me find a suitable replacement part online that would work to fix my problem? The leak puddles up in one area only thus far. I don't think the radiator neck or body is cracked. The GM overflow hose is very specific by the design. It is built specifically for the 2011 Camaro 2SS. The hose also has a lid top cover built on it. The lid cover purpose is to protect the overflow coolant reservoir from getting dirt and environmental contaminations inside the radiator fluid. I saw other GM overflow hoses for a 2012 Camaro 2SS. I'm not sure if that would fix this issue. Because those hoses are made specifically for each year. GM made slight changes to the Camaro 2SS from 2010 through 2015 I need to get this problem resolved before summer hits. I know AutoZone and NAPA sell radiator hose types. I've looked into those also. They don't seem to correctly fix the problem because their either to wide, big, thick, or to small. The aftermarket hosing won't have the protective cap lid cover on the hose. If the overflow coolant reservoir is not completely covered up. This would allow for dirt and environmental contaminates to enter. Should I look into the option of replacing the entire hose and coolant reservoir completely with an aftermarket version that can mount onto the radiator? Who would have this specific part in-stock? Is there a company that reproduces parts for said year, make, and model besides GM? I really want to stick with the original parts.

Mishimoto radiator hose set I think comes with all 3 hoses you can check them out.

Although it comes with 3, I believe it is the upper, lower, and then the steam vent hose. I believe OP is looking for the overfill hose that goes into the overfill tank.

Gotcha wasn’t sure what 3 hoses it came with.
Best bet go to local parts store and just get a hose the same size and make your own

Take it off, measure the length and get some from the local parts store off their bulk roll.

Problem with parts store hose is it wont have the little grommet that ‘seals’ it to the overflow tank so it will be a little more open than it is now

OP are you sure the cap isnt leaking?? Looks like it could be

Am I the only one concerned with that coolant color?

I used a coolant sealer treatment. It makes the coolant look golden brown. It is the hose leaking.

Exactly, the OEM GM hose comes with the grommet seal to cover the overflow tank. I'm trying to stick with the same parts used or new.

Yes, I'll need that also since it does not have one. Thanks for the overview and noticing it was not there.
