Here's what you should do instead:
1. Find a qualified mechanic: This is the best and safest option. A mechanic will properly diagnose the problem. They'll use specialized equipment to:
* Check for leaks: They'll use a leak detection machine to find where the refrigerant is escaping.
* Pressure test the system: This ensures the system can hold pressure.
* Evacuate the system: They remove any remaining refrigerant and air from the system before adding new refrigerant. This is crucial to prevent contamination.
* Add refrigerant and oil: The correct type and amount of refrigerant and compressor oil will be added.
* Add dye (optional): Adding a dye to the refrigerant helps locate leaks more easily in the future.
2. DIY (Not Recommended for Beginners): If you're mechanically inclined and comfortable working with refrigerant (which is dangerous if mishandled), you *could* attempt it yourself, but it's strongly discouraged unless you have experience. Improper handling can result in injury and further damage to your AC system. If you choose to proceed, you'll need:
* Refrigerant: You'll need the correct type of refrigerant for your vehicle. Check your owner's manual or a parts store for the correct type (it's likely R-134a for a 1998 model, but double check).
* Gauge set with hoses: This allows you to monitor pressure and add refrigerant safely.
* Leak detection equipment (optional but highly recommended): This will help you find the source of the leak before adding refrigerant.
* Vacuum pump: To evacuate the system before adding refrigerant.
Regardless of whether you choose a mechanic or DIY, you'll likely need to address the leak first. Simply adding refrigerant without fixing the leak is a waste of money and potentially harmful to your system.
Safety Warning: Refrigerant is harmful if inhaled or comes into contact with skin. Wear appropriate safety glasses and gloves if handling refrigerant. Work in a well-ventilated area.
In summary, while you can't simply recharge the AC, getting it professionally serviced is the most effective and safest way to restore your Buick LeSabre's air conditioning. Attempting a DIY repair without the proper knowledge and equipment could be costly and potentially dangerous.
