Leak Test - Process Overview

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.

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