General Service Precautions

NOTICE: Always use the correct fastener in the correct location. When you replace a fastener, use ONLY the exact part number for that application. General Motors will call out those fasteners that require a replacement after removal. General Motors will also call out the fasteners that require thread lockers or thread sealant. UNLESS OTHERWISE SPECIFIED, do not use supplemental coatings (paints, greases, or other corrosion inhibitors) on threaded fasteners or fastener joint interfaces. Generally, such coatings adversely affect the fastener torque and the joint clamping force, and may damage the fastener. When you install fasteners, use the correct tightening sequence and specifications. Following these instructions can help you avoid damage to parts and systems.

^ Never connect or disconnect connectors with the ignition switch in the "ON" position.
^ Do not disassemble any component which is designated as non-serviceable. Some manual air conditioning system components are not serviced separately and must be replaced as an assembly.

NOTICE: Use only Polyalklene Glycols Synthetic Refrigerant Oil (PAG) for internal circulation through the R-134a A/C system and only 525 viscosity mineral oil on fitting threads and O-rings. If lubricants other than those specified are used, compressor failure and/or seizure may result.

CAUTION: Before removing or installing any electrical unit(s), disconnect the negative battery cable to help prevent personal injury and/or damage to the vehicle or its components.
