Before servicing any vehicle, please be sure to read all of the following
precautions, which deal with personal safety, prevention of component
damage, and important points to take into consideration when servicing
a motor vehicle:
- Never open, service or drain the radiator or cooling
system when the engine is hot; serious burns can occur from the steam
and hot coolant.
- Observe all applicable safety precautions when working
around fuel. Whenever servicing the fuel system, always work in a well-ventilated
area. Do not allow fuel spray or vapors to come in contact with a spark,
open flame, or excessive heat (a hot drop light, for example). Keep a
dry chemical fire extinguisher near the work area. Always keep fuel in
a container specifically designed for fuel storage; also, always properly
seal fuel containers to avoid the possibility of fire or explosion. Refer
to the additional fuel system precautions later in this section.
- Fuel injection systems often remain pressurized,
even after the engine has been turned OFF. The fuel system pressure
must be relieved before disconnecting any fuel lines. Failure to do so
may result in fire and/or personal injury.
- Brake fluid often contains polyglycol ethers and
polyglycols. Avoid contact with the eyes and wash your hands thoroughly
after handling brake fluid. If you do get brake fluid in your eyes, flush
your eyes with clean, running water for 15 minutes. If eye irritation
persists, or if you have taken brake fluid internally, IMMEDIATELY seek
medical assistance.
- The EPA warns that prolonged contact with used engine
oil may cause a number of skin disorders, including cancer! You should
make every effort to minimize your exposure to used engine oil. Protective
gloves should be worn when changing oil. Wash your hands and any other
exposed skin areas as soon as possible after exposure to used engine oil.
Soap and water, or waterless hand cleaner should be used.
- All new vehicles are now equipped with an air bag
system, often referred to as a Supplemental Restraint System (SRS) or
Supplemental Inflatable Restraint (SIR) system. The system must be disabled
before performing service on or around system components, steering column,
instrument panel components, wiring and sensors. Failure to follow safety
and disabling procedures could result in accidental air bag deployment,
possible personal injury and unnecessary system repairs.
- Always wear safety goggles when working with, or
around, the air bag system. When carrying a non-deployed air bag, be sure
the bag and trim cover are pointed away from your body. When placing a
non-deployed air bag on a work surface, always face the bag and trim cover
upward, away from the surface. This will reduce the motion of the module
if it is accidentally deployed. Refer to the additional air bag system
precautions later in this section.
- Clean, high quality brake fluid from a sealed container
is essential to the safe and proper operation of the brake system. You
should always buy the correct type of brake fluid for your vehicle. If
the brake fluid becomes contaminated, completely flush the system with
new fluid. Never reuse any brake fluid. Any brake fluid that is removed
from the system should be discarded. Also, do not allow any brake fluid
to come in contact with a painted surface; it will damage the paint.
- Never operate the engine without the proper amount
and type of engine oil; doing so WILL result in severe engine damage.
- Timing belt maintenance is extremely important! Many
models utilize an interference-type, non-freewheeling engine. If the timing
belt breaks, the valves in the cylinder head may strike the pistons, causing
potentially serious (also time-consuming and expensive) engine damage.
Refer to the maintenance interval charts in the front of this manual for
the recommended replacement interval for the timing belt, and to the timing
belt section for belt replacement and inspection.
- Disconnecting the negative battery cable on some
vehicles may interfere with the functions of the on-board computer system(s)
and may require the computer to undergo a relearning process once the
negative battery cable is reconnected.
- When servicing drum brakes, only disassemble and
assemble one side at a time, leaving the remaining side intact for reference.
