cooling JEEP WRANGLER 2014 JK / 3.G User Guide

- Engine Temperature Warning Light
This light warns of an overheated engine condition.
If the light turns on and a warning chime sounds while driving, safely pull over and
stop the vehicle. If the A/C system is on, turn it off. Also, shift the transmission into
NEUTRAL and idle the vehicle. If the temperature reading does not return to normal,
turn the engine off immediately.
We recommend that you do not operate the vehicle or engine damage will occur. Have
the vehicle serviced immediately.
WARNING!
A hot engine cooling system is dangerous. You or others could be badly burned by
steam or boiling coolant.
- Brake Warning Light
The Brake Warning light illuminates when there is either a system malfunction or the
parking brake is applied. If the light is on and the parking brake is not applied, it
indicates a possible brake hydraulic malfunction, brake booster problem or an
Anti-Lock Brake System problem.
Please have your vehicle serviced immediately.
WARNING!
Driving a vehicle with the red brake light on is dangerous. Part of the brake system
may have failed. It will take longer to stop the vehicle. You could have a collision.
Have the vehicle checked immediately.
- Malfunction Indicator Light (MIL)
Certain conditions, such as a loose or missing gas cap, poor fuel quality, etc., may
illuminate the MIL after engine start. The vehicle should be serviced if the light stays
on through several typical driving cycles. In most situations, the vehicle will drive
normally and not require towing.
If the MIL flashes when the engine is running, serious conditions may exist that could
lead to immediate loss of power or severe catalytic converter damage. We recommend
you do not operate the vehicle. Have the vehicle serviced immediately.
WHAT TO DO IN EMERGENCIES
102

IF YOUR ENGINE OVERHEATS
In any of the following situations, you can reduce the potential for overheating by
taking the appropriate action:
• On the highways — slow down.
• In city traffic — while stopped, shift the transmission to NEUTRAL, but do notincrease engine idle speed.
NOTE:
There are steps that you can take to slow down an impending overheat condition:
• If your air conditioner (A/C) is on, turn it off. The A/C system adds heat to the engine cooling system and turning the A/C off can help remove this heat.
• You can also turn the temperature control to maximum heat, the mode control to floor and the blower control to high. This allows the heater core to act as a
supplement to the radiator and aids in removing heat from the engine cooling
system.
CAUTION!
Driving with a hot cooling system could damage your vehicle. If the temperature
gauge reads HOT (H), pull over and stop the vehicle. Idle the vehicle with the air
conditioner turned off until the pointer drops back into the normal range. If the
pointer remains on HOT (H), and you hear continuous chimes, turn the engine off
immediately, and call for service.
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 try to open a cooling system
pressure cap when the radiator or coolant bottle is hot.

WARNING!
• When temperatures are below the freezing point, electrolyte in a dischargedbattery may freeze. Do not attempt jump-starting because the battery could
rupture or explode and cause personal injury. Battery temperature must be
brought above the freezing point before attempting a jump-start.
• Take care to avoid the radiator cooling fan whenever the hood is raised. It can
start anytime the ignition switch is on. You can be injured by moving fan
blades.
• Remove any metal jewelry, such as watch bands or bracelets, that might make
an inadvertent electrical contact. You could be severely injured.
• Batteries contain sulfuric acid that can burn your skin or eyes and generate
hydrogen gas which is flammable and explosive. Keep open flames or sparks
away from the battery.
• Do not allow vehicles to touch each other as this could establish a ground
connection and personal injury could result.
• Failure to follow this procedure could result in personal injury or property
damage due to battery explosion.
• Do not connect the cable to the negative post (-) of the discharged battery. The
resulting electrical spark could cause the battery to explode and could result in
personal injury.
EMERGENCY TOW HOOKS
If your vehicle is equipped with tow hooks, they are mounted in the front and the rear.
NOTE:
For off-road recovery, it is recommended to use both of the front tow hooks to
minimize the risk of damage to the vehicle.
CAUTION!
Tow hooks are for emergency use only, to rescue a vehicle stranded off-road. Do not
use tow hooks for tow truck hookup or highway towing. You could damage your
vehicle. Tow straps are recommended when towing the vehicle; chains may cause
vehicle damage.
WARNING!
• Chains are not recommended for freeing a stuck vehicle. Chains may break,causing serious injury or death.
• Stand clear of vehicles when pulling with tow hooks. Tow straps may become
disengaged, causing serious injury.

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). If a non-OAT engine coolant (antifreeze) is introduced into
the cooling system in an emergency, the cooling system will need to be drained,
flushed, and refilled with fresh OAT coolant (conforming to MS-12106), by an
authorized dealer as soon as possible.
• Do not use water alone or alcohol-based engine coolant (antifreeze) products.
Do not use additional rust inhibitors or antirust products, as they may not be
compatible with the radiator engine coolant and may plug the radiator.
• This vehicle has not been designed for use with propylene glycol-based engine
coolant (antifreeze). Use of propylene glycol-based engine coolant (antifreeze)
is not recommended.

Severe Duty All Models
Change Engine Oil at 4000 miles (6,500 km) if the vehicle is operated in a dusty and
off road environment. This type of vehicle use is considered Severe Duty
Once A Month Or Before A Long Trip:
• Check engine oil level
• Check windshield washer fluid level
• Check the tire inflation pressures and look for unusual wear or damage
• Check the fluid levels of the coolant reservoir, brake master cylinder, powersteering and automatic transmission, and fill as needed
• Check function of all interior and exterior lights
Required Maintenance Intervals.
Refer to the maintenance schedules on the following page for the required mainte-
nance intervals.
At Every Oil Change Interval As Indicated By Oil Change Indicator System:
• Change oil and filter
• Rotate the tires. Rotate at the first sign of irregular wear, even if it occurs before the oil
indicator system turns on.
• Inspect battery and clean and tighten terminals as required
• Inspect automatic transmission fluid if equipped with dipstick
• Inspect brake pads, shoes, rotors, drums, hoses and park brake
• Inspect engine cooling system protection and hoses
• Inspect exhaust system
• Inspect engine air cleaner if using in dusty or off-road conditions
