Chevrolet Cruze Repair Manual: Work Stall Test Warning

Warning: One or more of the following guidelines may apply when performing specific required tests in the work stall:

When a test requires spinning the drive wheels with the vehicle jacked up, adhere to the following precautions:

• Do not exceed 56 km/h (35 mph) when spinning one drive wheel with the other drive wheel stopped. This limit is necessary because the speedometer indicates only one-half the actual vehicle speed under these conditions. Personal injury may result from excessive wheel spinning.
• If all of the drive wheels are spinning at the same speed, do not exceed 112 km/h (70 mph). Personal injury may result from excessive wheel spinning.
• All persons should stay clear of the rotating components and the balance weight areas in order to avoid possible personal injury.
• When running an engine in the repair stall for an extended period of time, use care not to overheat the engine and the transmission.

When a test requires jacking up the vehicle and running with the wheels and brake rotors removed, adhere to the following precautions:

• Support the suspension at normal ride height.
• Do not apply the brake with the brake rotors removed.
• Do not place the transmission in PARK with the drive axles spinning.
• Turn Off the ignition in order to stop the powertrain components from spinning.

When running an engine in the work stall, use the exhaust removal system to prevent breathing dangerous gases.

Air in the Power Steering System Caution

Caution: If the power steering system has been serviced, an accurate fluid level reading cannot be obtained unless air is bled from the steering system. The air in the fluid may cause pump cavitation noise and may cause pump damage over a period of time.

Avoid Chipping or Scratching the Coating Caution

Caution: Care should be taken to avoid chipping or scratching the coating when handling the suspension coil spring. Damage to the coating can cause premature failure.

Ball Stud Removal Caution

Caution: Do not free the ball stud by using a pickle fork or a wedge-type tool. Damage to the seal or bushing may result.

Belt Dressing Caution

Caution: Do not use belt dressing on the drive belt. Belt dressing causes the breakdown of the composition of the drive belt. Failure to follow this recommendation will damage the drive belt.

Brake Caliper Caution

Caution: Support the caliper with a piece of wire to prevent damage to the brake line.

Brake Fluid Effects on Paint and Electrical Components Caution

Caution: Avoid spilling brake fluid onto painted surfaces, electrical connections, wiring, or cables. Brake fluid will damage painted surfaces and cause corrosion to electrical components. If any brake fluid comes in contact with painted surfaces, immediately flush the area with water. If any brake fluid comes in contact with electrical connections, wiring, or cables, use a clean shop cloth to wipe away the fluid.

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.

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.

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.

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 Super DOT-4 brake fluid, or equivalent DOT-4 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.

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
