Jeep Wrangler: VEHICLE MAINTENANCE / 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 automatically
and may start at any time, whether the
engine is running or not.
- When working near the radiator cooling fan,
disconnect the fan motor lead or 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.
The best protection against carbon monoxide
entry into the vehicle body is a properly
maintained engine exhaust system.
If you notice a change in the sound of the
exhaust system; or if the exhaust fumes can be
detected inside the vehicle; or when the
underside or rear of the vehicle is damaged;
have an authorized technician inspect the
complete exhaust system and adjacent body
areas for broken, damaged, deteriorated, or
mispositioned parts...
Check the engine, battery (if equipped),
intercooler (if equipped), and Motor Generator
Unit (MGU) (if equipped) coolant (antifreeze)
protection every 12 months (before the onset of
freezing weather, where applicable)...
Other information:
TCS monitors the amount of wheel spin of each
of the driven wheels. If wheel spin is detected,
the TCS may apply brake pressure to the
spinning wheel(s) and/or reduce engine power
to provide enhanced acceleration and stability.
A feature of the TCS, Brake Limited Differential
(BLD), functions similarly to a limited slip
differential and controls the wheel spin across a
driven axle...
If applicable, refer to the “Hybrid Supplement”
for additional information.
Release both the hood latches.
Hood Latch Locations
Raise the hood and locate the safety latch,
located in the middle of the hood opening. Push
the safety latch to the right to open the hood...
