where do I add freon to my air conditioning unit on a 1997 chevy truck?
2.5 pound or at least that's what my 1990 Chevrolet k1500 says it takes you might can look on the sticker on top of the silverish cylinder at the top left under the hood.
to install freon in your 98 lumina you will need to purchase the freon (r134a) and a hose kit from your local parts store. from there, locate the low pressure side of your ac system, usually by the radiator, but sometimes next to the condenser. The hose will only fit on one, so if it doesnt fit on the first you find, find the other. Then, with the car running and the ac on full punture the can and allow freon to enter the system.. That's it! THE 98 WOULD USE R34 AND CAN BE FOUND AT SOME OF THE AUTO PARTS STORES. THEY ALSO SELL A ADAPTER TO SCREW ONTO THE INLET OR SUCTION SIDE OF THE SYSTEM. INSTROCTIONS COME WITH THE FREON
