Vehicle Damage Warnings

CAUTION:
Proper Brake Fluid
Use only Delco Supreme 11(r) Brake Fluid, GM P/N 1052535, or equivalent DOT 3 brake fluid from a clean, sealed container. Do not use any fluid from a container which is wet with water. Do not use DOT 5 silicone brake fluid. Improper brake fluid, water, or mineral oil in the fluid may cause the brake fluid to boil or the rubber components to deteriorate.

Brake Fluid Spills
Avoid spilling brake fluid on any of the vehicle's painted surfaces, wiring cables or electrical connectors. Brake fluid will damage paint and electrical connections. If any fluid is spilled on the vehicle, flush area with water to lessen damage.

FASTENERS
Replacement
Always use the correct fastener in the proper 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.

Torqueing
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 joint clamping force, and may damage the fastener. When you install fasteners, use the correct sequence and tightening specifications. Following these instructions can help you avoid damage to parts and systems.

FLUSHING THE SYSTEM
It is recommended that the entire hydraulic system be thoroughly flushed with clean brake fluid. Approximately 0.95 liters (one quart) of fluid is required to flush the hydraulic system. When flushing the system use the steps specified in the Manual Bleeding procedures. Some of the reasons to flush the system are:

^ whenever new parts are installed in the hydraulic system.
^ if there is any doubt as to the grade of the fluid in the system.
^ if fluid has been used which contains the slightest trace of
^ petroleum based fluids. All rubber parts that have been subjected to a contaminated fluid must be replaced.
