Leak Testing the Refrigeration System

Perform a refrigerant leak test on the refrigeration system whenever one of the following conditions exist:
^ A leak is suspected due to a system indication of a low charge.
^ After any service operation which disturbs the components, lines or connections.

IMPORTANT: Vehicles equipped with an early warning system for low refrigerant may set low refrigerant codes.

Many methods and special tools are available for leak testing. Always use care and diligence, no matter which tool you are using.
