Buick Regal: Component Fastener Tightening Caution

CAUTION: Replacement components must be the correct part number for the application. Components requiring the use of the thread locking compound, lubricants, corrosion inhibitors, or sealants are identified in the service procedure. Some replacement components may come with these coatings already applied. Do not use these coatings on components unless specified. These coatings can affect the final torque, which may affect the operation of the component. Use the correct torque specification when installing components in order to avoid damage.

CORRECT REFRIGERANT LUBRICANT CAUTION

CAUTION: Use only the lubricant specified for this vehicles refrigerant system. Do not mix refrigerant oils which may result in system contamination and unknown reaction by-products which may cause HVAC System failure.

COVER AND PLUG OPENINGS CAUTION

CAUTION: Cap the fittings and plug the holes when servicing the fuel system in order to prevent dirt and other contaminants from entering the open pipes and passages.

DRIVE AXLE CAUTION

CAUTION: Support the lower control arms in the normal horizontal position in order to avoid damage to the drive axles. Do not operate the vehicle in gear with the wheels hanging down at full travel.

DRIVE BELT TENSIONER PIVOT BOLT CAUTION

CAUTION: Failure to properly tighten the drive belt tensioner pivot bolt to the specified torque value will cause the bolt to fail, and also damage to other engine components.

EMBLEM/NAMEPLATE REMOVAL HEAT CAUTION

CAUTION: Applying excessive heat to the emblem/nameplate may damage the paint and surrounding panel surfaces during removal. Heat temperature SHOULD NOT exceed 79ºC (175ºF).

ENGINE COOLANT THERMOSTAT HOUSING CAUTION

CAUTION: Use care when performing this procedure. Use of excessive force may damage the coolant thermostat.

EXTERIOR TRIM EMBLEM REMOVAL CAUTION

CAUTION: Use a plastic, flat-bladed tool to prevent paint damage when removing an emblem/name plate.

FASTENER CAUTION

CAUTION: Use the correct fastener in the correct location. Replacement fasteners must be the correct part number for that application. Do not use paints, lubricants, or corrosion inhibitors on fasteners, or fastener joint surfaces, unless specified. These coatings affect fastener torque and joint clamping force and may damage the fastener. Use the correct tightening sequence and specifications when installing fasteners in order to avoid damage to parts and systems. When using fasteners that are threaded directly into plastic, use extreme care not to strip the mating plastic part(s). Use hand tools only, and do not use any kind of impact or power tools. Fastener should be hand tightened, fully seated, and not stripped.

FRONT PARKING CAMERA CONNECTOR CAUTION

CAUTION: When installing the wiring harness connector of the front parking camera on vehicles equipped with forward range radar, verify that the wiring harness connector is properly installed. Failure to properly install the wiring harness connector may result in improper performance and/or damage to the forward range radar.

FUEL AND EVAPORATIVE EMISSION HOSE/PIPE CONNECTION CLEANING CAUTION

CAUTION: Clean all of the following areas before performing any disconnections in order to avoid possible contamination in the system:

• The fuel pipe connections
• The hose connections
• The areas surrounding the connections
