92 Cutlass Supreme heater hose question?

[Rusty280Z]

92 Supreme SL, 3.4 DOHC I have a fixture located on top of the heater hose metal housing prior to the engine block that looks like a grease fixture. I cannot find this item in my Chilton's manual. I did notice a very small amount of coolant at the bottom of the fitting. Is this a grease fixture? Any reponse would be appreciated, Russ

Im not 100% sure, with your car, but those fittings are usually for releasing air from the system. It kinda looks like a grease fitting, or a brake bleader screw... To know for sure, start your car, and let it warm up, once its warn, loosen that fitting just a little, and steam/air chould come out, your soposed to crack it opened, untill all the air comes out, then tighten it...
Hope this helps

Roudy4x4 is correct, that is an air bleeder screw.
