Cooling System
WARNING!
• You or others can be badly burned by hot
engine coolant (antifreeze) or steam
from your radiator. If you see or hear
steam coming from under the hood, do
not open the hood until the radiator has
had time to cool. Never open a cooling
system pressure cap when the radiator
or coolant bottle is hot.
• Keep hands, tools, clothing, and jewelry
away from the radiator cooling fan when
the hood is raised. The fan starts auto-
matically and may start at any time,
whether the engine is running or not.
WARNING!
• When working near the radiator cooling
fan, turn the ignition to the OFF mode.
The fan is temperature controlled and
can start at any time the ignition is in the
ON mode.
Coolant Checks
Check the engine and, intercooler (if
equipped) coolant (antifreeze) protection ev-
ery 12 months (before the onset of freezing
weather, where applicable). If the engine
and, intercooler (if equipped) is dirty or rusty
in appearance, the system should be drained,
flushed and refilled with fresh OAT coolant
(conforming to MS.90032) by an authorized
dealer. Check the front of the A/C condenser
(if equipped) or radiator for any accumulation
of bugs, leaves, etc. If dirty, clean by gently
spraying water from a garden hose vertically
down the face of the A/C condenser (if
equipped) or the back of the radiator core.
Check the engine and, intercooler (if
equipped) cooling system hoses for brittle
rubber, cracking, tears, cuts, and tightness ofthe connection at the coolant recovery bottle
and radiator. Inspect the entire system for
leaks. DO NOT REMOVE THE COOLANT
PRESSURE CAP WHEN THE COOLING SYS-
TEM IS HOT.
Brake System
In order to assure brake system performance,
all brake system components should be in-
spected periodically. Refer to the “Mainte-
nance Plan” in this section for the proper
maintenance intervals.
WARNING!
Riding the brakes can lead to brake failure
and possibly a collision. Driving with your
foot resting or riding on the brake pedal
can result in abnormally high brake tem-
peratures, excessive lining wear, and pos-
sible brake damage. You would not have
your full braking capacity in an emergency.
Fluid Level Check — Brake Master Cylinder
The fluid level of the master cylinder should
be checked whenever the vehicle is serviced,
or immediately if the brake system warning
