Leak Test - Process Overview

CAUTION: Do not operate the detector in a combustible atmosphere since its sensor operates at high temperature. Personal injury on damage to the equipment may result.

A refrigerant leak test should be performed on the system whenever a leak is suspected due to system indication of low charge or after any service operation which disturbs the components, lines, or connections. Many methods and special tools are available for this purpose; however, no matter which tool is used, care and diligence are the biggest keys to success.

Important
^ Vehicles equipped with an early warning system for "low refrigerant" may set low refrigerant codes."
