Safety Restraint System -
Inspection
WARNING
Failure to properly inspect and main-
tain
restraint systems can lead to in-
jury or loss of life. Without periodic in-
spection and maintenance to detect
unsafe conditions, seat restraint com-
ponents can wear out or not protect
you in an accident.
WARNING
It is important to remember that any
time
a vehicle is involved in an acci-
dent, the entire seat belt system must
be replaced. Unexposed damage
caused by the stress of an accident
could prevent the system from func-
tioning properly the next time it is
needed. Failure to comply may result
in death or personal injury.
Seat Belt Inspection Points
MAINTENANCE - Safety Restraint System - Inspection
Check the coolant level after each trip. Add
coolant as necessary. Y
ou may find your
coolant level is not up to the correct level
soon after you have filled the radiator. This
may be because all the trapped air in the
system has not yet been purged. It takes a
little time for all of the air to leave the
system after you fill your radiator.
Use a solution of half ethylene glycol
antifreeze and half water for best heater
performance. Do not use more than 60
percent concentration of antifreeze, as a
shortened heater life will result.
After servicing the cooling system, monitor
the cooling system for several days.
Trapped air inside the engine needs time
to escape and will lower the coolant level in
the surge tank when it does. As part of
each pre-trip inspection, look for signs of
