Jeep Wrangler: Cooling System / Engine Coolant Level — 2.0L
WARNING!
- Do not open hot engine cooling system.
Never add engine coolant (antifreeze) when
the engine is overheated. Do not loosen or
remove the cap to cool an overheated
engine. Heat causes pressure to build up in
the cooling system. To prevent scalding or
injury, do not remove the pressure cap
while the system is hot or under pressure.
- Do not use a pressure cap other than the
one specified for your vehicle. Personal
injury or engine damage may result.
With the engine OFF and cold, the level of the
engine coolant should be within the OK range
between the ADD and FULL range on the
dipstick.
- Remove the cap with level dipstick from
the engine coolant bottle.
- Clean off the coolant from the dipstick.
- Rest the cap on the opening of the coolant
bottle without tightening the cap.
- Remove the cap with dipstick and check the
coolant level on the dipstick.
The radiator normally remains completely full,
so there is no need to remove the radiator/
coolant pressure cap unless checking for
engine coolant freeze point or replacing
coolant. Advise your service attendant of this.
As long as the engine operating temperature is
satisfactory, the coolant bottle need only be
checked once a month.
When additional engine coolant is needed to
maintain the proper level, only OAT coolant that
meets the requirements of the manufacturer
Material Standard MS.90032 should be added
to the coolant bottle. Do not overfill.
The coolant bottle provides a quick visual
method for determining that the coolant level is
adequate. With the engine OFF and cold, the
level of the engine coolant (antifreeze) in the
bottle should be between the ranges indicated
on the bottle...
NOTE:
When the vehicle is stopped after a few miles/
kilometers of operation, you may observe vapor
coming from the front of the engine compartment.
This is normally a result of moisture from
rain, snow, or high humidity accumulating on
the radiator and being vaporized when the thermostat
opens, allowing hot engine coolant (antifreeze)
to enter the radiator...
Other information:
CAUTION!
Mixing of engine coolant (antifreeze) other
than specified Organic Additive Technology
(OAT) engine coolant (antifreeze), may
result in engine damage and may decrease
corrosion protection. Organic Additive Technology
(OAT) engine coolant is different and
should not be mixed with Hybrid Organic
Additive Technology (HOAT) engine coolant
(antifreeze) or any “globally compatible”
coolant (antifreeze)...
Fully press the clutch pedal before shifting
gears. As you release the clutch pedal, lightly
press the accelerator pedal.
You should always use FIRST gear when starting
from a standing position.
NOTE:
A certain amount of noise from the transmission
is normal...
