INFORMATION

Subject:
PureGuard 2 Operating Alert

Models:
1998 and Prior Passenger Cars and Trucks with R134a A/C Systems

A number of PureGuard 2's have been returned from the field as the result of damage from flooding the unit with oil and liquid refrigerant. Improper service procedures and unique A/C service conditions can cause this. To ensure oil and liquid refrigerant never enter the PureGuard 2, a protective device, called J-41810-100A Active Flow Control (AFC), has been shipped to every General Motors dealership. The AFC MUST be installed to prevent damage to the PureGuard 2.

To assure maximum performance of your PureGuard 2 Refrigerant Identifier and ACR4 Recovery, Recycle and Recharging Station, below are performance tips that need to be followed. Place a copy of this bulletin with the ACR4 instruction manual in the side pocket of the ACR4.
