INSPECTION

WARNING

Use care to prevent refrigerant from touching skin or eyes. Liquid refrigerant, when

exposed to air, quickly evaporates and will freeze skin or eye tissues. Serious

injury or blindness may result if you come in contact with liquid refrigerant.

Refrigerant R-134a air conditioning systems should not be pressure tested or leak

tested with compressed air. Combustible mixtures or air and R-134a may form,

resulting in a fire or explosion, which could cause personnel injury or death.

NOTE

Refrigerant is odorless. As a result, all of it may leak away and not be noticed until system

stops cooling. All vehicle refrigerant systems lose some refrigerant depending on

condition of system. Higher loss rates signal a need to locate and repair leaks.

Leaks are most often found at compressor hose connections and at various fittings and

joints in system. If unapproved replacement hoses are installed, refrigerant can be lost

through hose permeation.

1. Visually inspect refrigerant system for air conditioning lubricant leakage and corrosion and damage to

lines, hoses, and other components.

2. Visually inspect lowest points of fittings, hoses, and lines for indication of lubricant leakage.
