2015 JEEP CHEROKEE radiator hose

•Completely inspect the underbody of your vehicle.
Check tires, body structure, steering, suspension, and
exhaust system for damage.
•Inspect the radiator for mud and debris and clean as
required.
•Check threaded fasteners for looseness, particularly on
the chassis, drivetrain components, steering, and sus-
pension. Retighten them, if required, and torque to the
values specified in the Service Manual.
•Check for accumulations of plants or brush. These
things could be a fire hazard. They might hide damage
to fuel lines, brake hoses, axle pinion seals, and
propeller shafts.
•After extended operation in mud, sand, water, or
similar dirty conditions, have the radiator, fan, brake
rotors, wheels, brake linings, and axle yokes inspected
and cleaned as soon as possible.
WARNING!
Abrasive material in any part of the brakes may cause
excessive wear or unpredictable braking. You might
not have full braking power when you need it to
prevent a collision. If you have been operating your
vehicle in dirty conditions, get your brakes checked
and cleaned as necessary.
•If you experience unusual vibration after driving in
mud, slush or similar conditions, check the wheels for
impacted material. Impacted material can cause a
wheel imbalance and freeing the wheels of it will
correct the situation.
POWER STEERING
The electric power steering system will give you good
vehicle response and increased ease of maneuverability
in tight spaces. The system will vary its assist to provide

Engine Coolant Checks
Check the engine coolant (antifreeze) protection every 12
months (before the onset of freezing weather, where
applicable). If the engine coolant (antifreeze) is dirty, the
system should be drained, flushed, and refilled with
fresh OAT coolant (conforming to MS-12106) by an
authorized dealer. Check the front of the A/C condenser
for any accumulation of bugs, leaves, etc. If dirty, clean by
gently spraying water from a garden hose vertically
down the face of the condenser.
Check the engine cooling system hoses for brittle rubber,
cracking, tears, cuts, and tightness of the connection at
the coolant recovery bottle and radiator. Inspect the
entire system for leaks.
With the engine at normal operating temperature (but
not running), check the cooling system pressure cap for
proper vacuum sealing by draining a small amount of
engine coolant (antifreeze) from the radiator drain cock.
If the cap is sealing properly, the engine coolant (anti-
freeze) will begin to drain from the coolant recovery
bottle. DO NOT REMOVE THE COOLANT PRESSURE
CAP WHEN THE COOLING SYSTEM IS HOT.
Cooling System — Drain, Flush And Refill
NOTE:Some vehicles require special tools to add coolant
properly. Failure to fill these systems properly could lead
to severe internal engine damage. If any coolant is
needed to be added to the system please contact your
local authorized dealer.
If the engine coolant (antifreeze) is dirty or contains
visible sediment, have an authorized dealer clean and
flush with OAT coolant (antifreeze) (conforming to MS-
12106).
Refer to the “Maintenance Schedule” for the proper
maintenance intervals.

MAINTAINING YOUR VEHICLE 687

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.
•Do not overfill the coolant expansion bottle.
•Check the coolant freeze point in the radiator and in
the coolant expansion bottle. If engine coolant (anti-
freeze) needs to be added, the contents of the coolant
expansion bottle must also be protected against freez-
ing.
•If frequent engine coolant (antifreeze) additions are
required, the cooling system should be pressure tested
for leaks.
•Maintain engine coolant (antifreeze) concentration at a
minimum of 50% OAT coolant (conforming to MS-
12106) and distilled water for proper corrosion protec-
tion of your engine which contains aluminum compo-
nents.
•Make sure that the coolant expansion bottle overflow
hoses are not kinked or obstructed.
•Keep the front of the radiator clean. If your vehicle is
equipped with air conditioning, keep the front of the
condenser clean.
•Do 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 engine coolant (antifreeze)
performance, poor gas mileage, and increased emis-
sions.
Brake System
In order to assure brake system performance, all brake
system components should be inspected periodically.
Refer to the “Maintenance Schedule” for the proper
maintenance intervals.
