2004 JEEP LIBERTY coolant level

Adding Coolant
When adding coolant, a minimum solution of 50% rec-
ommended ethylene glycol antifreeze coolant in water
should be used. Use higher concentrations (not to exceed
70%) if temperatures below -37ÉF (-38ÉC) are anticipated.
Use only high purity water such as distilled or deionized
water when mixing the water/antifreeze solution. The
use of lower quality water will reduce the amount of
corrosion protection in the engine cooling system.
Please note that it is the owner's responsibility to main-
tain the proper level of protection against freezing ac-
cording to the temperatures occurring in the area where
the vehicle is operated.
NOTE:Mixing coolant types will decrease the life of the
engine coolant and will require more frequent engine
coolant changes.
Cooling System Pressure Cap
The cap must be fully tightened to prevent loss of
coolant, and to insure that coolant will return to the
radiator from the coolant bottle.
The cap should be inspected and cleaned if there is any
accumulation of foreign material on the sealing surfaces.
WARNING!
The warning words DO NOT OPEN HOT on the
cooling system pressure cap are a safety precaution.
Never add coolant when the engine is overheated.
Do not loosen or remove the cap to cool an over-
heated 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.

Coolant Level
The coolant recovery bottle provides a quick visual
method for determining that the coolant level is ad-
equate. The coolant level must be at or above the COLD
FULL level on the bottle. The radiator normally remains
completely full, so there is no need to remove the radiator
cap unless checking for 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 coolant is needed to maintain the
proper level, it should be added to the coolant recovery
bottle. Do not overfill.
Points To Remember
NOTE:When the vehicle is stopped after a few miles of
operation, you may observe vapor coming from the front
of the engine compartment. This is normally a result of
306 MAINTAINING YOUR VEHICLE

moisture from rain, snow, or high humidity accumulat-
ing on the radiator and being vaporized when the
thermostat opens, allowing hot water to enter the radia-
tor.
If an examination of your engine compartment shows no
evidence of radiator or hose leaks, the vehicle may be
safely driven. The vapor will soon dissipate.
²Do not overfill the coolant bottle.
²Check coolant freeze point in the system.
²If frequent coolant additions are required, or if the
level in the recovery bottle does not drop when the
engine cools, the cooling system should be pressure
tested for leaks.
²Maintain coolant concentration to 50% ethylene glycol
antifreeze (minimum) in water for proper corrosion
protection of your engine that contains aluminum
components.
²Make sure that the radiator and coolant bottle hoses
are not kinked or obstructed.
²Do not change the thermostat for summer or winter
operation. If replacement is ever necessary, install
ONLY the correct type thermostat. Other designs may
result in unsatisfactory cooling performance, poor gas
mileage, and increased emissions.
Hoses and Vacuum/Vapor Harnesses
Inspect surfaces of hoses and nylon tubing for evidence
of heat and mechanical damage. Hard or soft spots,
brittle rubber, cracking, tears, cuts, abrasions, and exces-
sive swelling indicate deterioration of the rubber.
Pay particular attention to the hoses nearest to high heat
sources such as the exhaust manifold. Inspect hose rout-
ing to be sure hoses do not touch any heat source or
moving component that may cause heat damage or
mechanical wear.

326 MAINTAINING YOUR VEHICLE

²Off-road or desert driving.
NOTE:Most vehicles are operated under the conditions
listed for Schedule ªB.º
Second is ScheduleªAº. It is for vehicles that are not
operated under any of the conditions listed under Sched-
ule ªB.º
Use the schedule that best describes your driving condi-
tions. Where time and mileage are listed, follow the
interval that occurs first.
CAUTION!
Failure to perform the required maintenance items
may result in damage to the vehicle.
At Each Stop for Fuel
²Check the engine oil level about 5 minutes after a fully
warmed engine is shut off. Checking the oil level while
the vehicle is on level ground will improve the accu-
racy of the oil level reading. Add oil only when the
level is at or below the ADD or MIN mark.
²Check the windshield washer solvent, add as required.
Once a Month
²Check the tire pressure and look for unusual wear or
damage.
²Inspect the battery, and clean and tighten the terminals
as required.
²Check the fluid levels of the coolant reservoir, brake
master cylinder, and transmission, and add as needed.
²Check all lights and all other electrical items for correct
operation.

At Each Oil Change
²Change the engine oil filter.
²Inspect the exhaust system.
²Inspect brake hoses.
²Check the coolant level, hoses, and clamps.
²Inspect manual transmission fluid level Ð if
equipped.
²Rotate the tires at each oil change interval shown on
Schedule ªAº 6,000 miles (10 000 km) or every other
interval shown on Schedule ªBº 6,000 miles (10 000
km).
²After completion of off-road operation, the underside
of the vehicle should be thoroughly inspected. Exam-
ine threaded fasteners for looseness.
