Seems like every time I fix something, something else breaks. Now that I have changed the valve cover gaskets, I have a coolant leak. It's coming from a small plastic valve located under the high coolant fill tank by the windshield. It's a small cylinder with an arrow pointing toward the tank, so I assume it's a check valve. I see one that looks like it listed at Eckler's that calls it a hot water control valve, but it's only a cylinder with a hose connected to both ends. Coolant is coming out around the end cap after a drive and then I shut the car shut off.
Does anyone have any idea where I can find one locally? Maybe Chevy dealer? I can't find anything on line for AutoZone, O'reilly's, Napa, or Advance Auto. I can post a picture later if needed. I have been page by page through the service manual coolant section and this part isn't listed. Thanks for any help.

Edit:

O'Reilly's can have one here by 11 am, so I'm good. In case someone searches for this, it's O'reilly's part number 74795 Climate control heater - in line restrictor $10.99

Thank you. I need to replace both of inlet and Outlet hoses right there. Noticed just the other day they are becoming one further down..

In case we're not talking about the same item, here's a picture:

I think so, I'm looking at the hoses that go from under the upper pressure tank / heater core to water pump. 20 year old hoses. Thank you for posting up the pic

I just replaced mine last year it's a heater check valve. I got mine at Rock auto for less then five bucks

Was yours leaking coolant?

No I was just replacing some hoses and I thought I might as well replace the valve becouse of how cheap it was.

Well, a follow up: The valve I got at O'Reilly's leaked worse than the one I took out. I didn't even have to start the car. I took it out an blew through it and air came out all around the seam. I took it back and bought one at Advance Auto and so far it is holding. Same part # and same price so it's probably made by the same company.

For what it's worth the one I bought was in a Delco box from the mid 90's and it was fine
