Start By:
Unlock the latch that holds the hood shut. Raise the hood and install the strut that holds the hood in the raised position.
Recover the air conditioner refrigerant from the air conditioner system. The correct charge is 1.1 kg (2.45 lb). Refer to Service Manual, SENR5664, "Air Conditioning and Heating Systems with R-134a Refrigerant" for the correct procedure. Refer to Special Publication, NEDG5065, "Air Conditioning Tools" for the correct tools.
Personal injury can result from contact with refrigerant.Contact with refrigerant can cause frost bite. Keep face and hands away to help prevent injury.Protective goggles must always be worn when refrigerant lines are opened, even if the gauges indicate the system is empty of refrigerant.Always use precaution when a fitting is removed. Slowly loosen the fitting. If the system is still under pressure, release it slowly in a well ventilated area.Personal injury or death can result from inhaling refrigerant through a lit cigarette.Inhaling air conditioner refrigerant gas through a lit cigarette or other smoking method or inhaling fumes released from a flame contacting air conditioner refrigerant gas, can cause bodily harm or death.Do not smoke when servicing air conditioners or wherever refrigerant gas may be present.Use a certified recovery and recycling cart to properly remove the refrigerant from the air conditioning system.
Put identification marks on all hose, on all tubes and on all wires for installation purposes. Plug all hoses and tubes. This helps prevent fluid loss, and this helps to keep contaminants from entering the system.

Check the adjustment of the V-belt.
Check the tension in V-belt (3) midway between the refrigerant compressor and the crankshaft pulley. A V-belt that is adjusted correctly will deflect approximately 10 mm (0.4 inch).
If the V-belt is not at the correct tension then loosen bolt (4), bolt (6), and bolt (7) before returning to Step 3.a.
