Just brought the car home. Wasn't getting fuel, and while replacing battery and doing some diagnosing, my gorilla arms busted this T fitting circled in green. Appears it comes from the water pump. The schrader valve confuses me. Is it an A/C cooling line? Sorry for the ignorance, i'm new to the Camaro life. I looked at it briefly, but cannot remember where the two larger lines go. Being that they are crimped lines, makes me think they handle high pressure. thanks in advance!

Btw, this was my grandpa's car, documented 94k miles, garage stored in AZ, it's cherry.

 

Not a Schrader valve. That's an air bleeder valve for the coolant system, on the heater lines. Shoebox has a photo and a diagram of the hoses.

Hoses - see parts #4 and #5:

Bleeder valve - Shoebox's 95 is slightly different than your 93, lacking the third hose out the side:

Bleeding air out of the cooling system is critical with the LT1 engine, due to the use of a "reverse flow" cooling system (coolant from radiator is directed to the heads first, rather than the block).

 

@Injuneer you are the man. Thank you!
