CAUTION: To prevent internal damage to the flexible coupling of the catalytic converter assembly, the converter must be supported. The vertical movement at the rear of the catalytic converter assembly must not exceed 6 degrees up or down.
CLEAN, DRY, LOW PRESSURE GAS SOURCE CAUTION
CAUTION: Use the Evaporative Emission (EVAP) System Tester (EEST) GE 41413-A in order to provide a clean, dry, low pressure nitrogen gas source. Do not substitute any other pressurized source, gas or otherwise. Damage may result to the EVAP system, test equipment or cause a safety risk.
CLEARCOAT/ULTRAVIOLET SCREENERS CAUTION
CAUTION: Removing more than 0.5 mils of the clearcoat can result in early paint failure. The clearcoat contains ultraviolet screeners. Do not finesse sand more than what is required to remove the defect.
CLUTCH HYDRAULIC SYSTEM LUBRICANT CAUTION
CAUTION: Do not use mineral or paraffin-base oil in the clutch hydraulic system.
These fluids may damage the rubber parts in the cylinders.
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.
COMPRESSED AIR SHOULD NOT EXCEED 98 KPA (14 PSI) CAUTION
CAUTION: When using compressed air to remove components, air pressure should not exceed 98 kPa (14 psi).
CORRECT REFRIGERANT CAUTION
CAUTION: Use only the refrigerant and the charge amount specified in "Refrigerant System Specifications" found in HVAC Service Manual or the vehicles under hood refrigerant label. Use of incorrect refrigerant or charge amounts may result in poor system performance and premature system failure.
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.
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.
ENGINE COOLANT THERMOSTAT HOUSING CAUTION
CAUTION: Use care when performing this procedure. Use of excessive force may damage the coolant thermostat.
ENGINE LIFTING CAUTION
CAUTION: When raising or supporting the engine for any reason, do not use a jack under the oil pan, any sheet metal, or the crankshaft pulley. Lifting the engine in an unapproved manner may cause component damage.
ENGINE MOUNTING CAUTION
CAUTION: Broken engine mountings can cause misalignment of certain drive-train components. Misalignment of drive-train components causes eventual destruction of the drive-train components.
If one engine mount breaks, the rest of the engine mounts will have increased stress put on them. This could cause the rest of the engine mounts to break.
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.
FILLING THE MASTER CYLINDER CAUTION
CAUTION: When filling the master cylinder, use only Delco Supreme 11, GM P/N 12377967 (Canadian P/N 992667), or equivalent DOT 3 brake fluid. Do not use a container which has been used for petroleum based fluids, or a container which is wet with water. Petroleum based fluids will cause swelling and distortion of rubber parts in the hydraulic brake system, and water will mix with brake fluid, lowering the boiling point. Keep all fluid containers capped to prevent contamination.
FLEX DECOUPLER CAUTION
CAUTION: Do not over-flex or damage the flex joint when moving the flex joint from the normal mounting position.
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:
FUEL PRESSURE CAUTION
CAUTION: Do not allow the fuel pressure to exceed the specified value because damage to the fuel pressure regulator or the fuel pressure gauge may result.
FUEL TANK STRAP FASTENER CAUTION
CAUTION: Tighten the strap fasteners by steps, alternating between the fasteners, until the specified torque is reached. A failure to tighten the strap fasteners as specified will cause the bottom of the tank to flex upward.
This will result in the fuel gauge indicating that there is fuel remaining in the tank when the tank is empty.
