Air Conditioner Instruction Plate Location
Illustration 1 g03715102
(1) Instruction plate Air conditioner instruction plate (1) identifies R-134a as the system refrigerant and lists the capacity of the refrigerant system. The air conditioner instruction plate is located inside the right access panel on the right side of the radiator. The Polyalkylene Glycol (PAG) refrigerant oil used to lubricate the refrigerant compressor is 4C-2959 Air Conditioner Oil.Air Conditioning System Charging Port Locations

(3) Refrigerant compressor Glossary of Terms
Ambient air - Outside airCharge - The charge is a predetermined amount of refrigerant that is put into the air conditioning system by weight.Compressor - The compressor is a component in the system that increases the pressure of the refrigerant in the system by pumping.Condenser - The condenser is a component in the system that changes the refrigerant from gas to a liquid.Contaminants - Dirt, water, and airDesiccant - The desiccant is part of the receiver or the accumulator that removes the moisture from the air conditioning system. Detecting - Detecting is finding the source of the problem in the system.Diaphragm - The diaphragm is a rubber-like material. The diaphragm divides the upper chamber and the lower chamber in the thermostatic expansion valve.Discharge - The discharge is the removal of some of the refrigerant or the removal of all the refrigerant from the air conditioning system.Discharge side - The discharge side is the outlet from the compressor to the condenser coil.Evacuating - Evacuating is the removal of air and moisture from the air conditioning system. Evaporation - Evaporation is the process of changing a liquid to a vapor.Evaporator - The evaporator is the component in the air conditioning system that changes the refrigerant from a liquid to a gas by the addition of heat. Expansion Valve - The expansion valve is a component in the air conditioning system that regulates the flow of liquid refrigerants into the evaporator.Fluid - Fluid is a liquid or a gas.Formation of Bubbles - The formation of bubbles in the sight glass of the receiver-dryer indicates that too little refrigerant remains.Flush - To remove foreign material and oil from the system, flush the system with fluid that is approved. The fluid must be approved by the SAE standard and approved by the ISO standard.Freeze - Freezing can cause a liquid to become a solid.Gas - gas is a vapor which contains no liquid.Graduated Container - A graduated container is a glass scale that is used to measure a fluid in ounces or milliliters.Heat - Thermal energyIdentifier - The identifier is an instrument for testing the system. The identifier is used for determining the type of refrigerant in the system. The identifier is also used for determining the percent of air in the system.In-line dryer - A component of the air conditioning system that removes contaminants (moisture) from the systemLatent heat - The quantity of heat needed to cause a change of state between liquid and gas of the refrigerant without changing the temperature
