The Alero was a compact car manufactured by Oldsmobile from 1999 to 2004. The air -onditioning system on the Oldsmobile Alero runs on R-134a refrigerant. Over time, refrigerant can leak from the condensing coils, causing the air-conditioning system to malfunction. Little to no cool air from the air-conditioning vents is usually the first sign that your system is running low on refrigerant. Fortunately, recharging the air-conditioning system on an Oldsmobile Alero is pretty simple; all you need is an air-conditioning recharge kit.
Park your Alero in a safe location. Engage the parking brake to prevent your vehicle from rolling while the engine is idling. Collect all your materials before you begin. Due to the sensitive nature of refrigerant, have everything on hand while recharging your air-conditioning system.
