2013 Ram 1500 cooling

•Your vehicle has also been equipped with a TPMS malfunction indicator to indicate
when the system is not operating properly. The TPMS malfunction indicator is
combined with the low tire pressure telltale. When the system detects a malfunction,
the telltale will flash for approximately one minute and then remain continuously
illuminated. This sequence will continue each time the vehicle is restarted as long as
the malfunction exists.
• When the malfunction indicator is illuminated, the system may not be able to detect or signal low tire pressure as intended. TPMS malfunctions may occur for a
variety of reasons, including the installation of replacement or alternate tires or
wheels on the vehicle that prevent the TPMS from functioning properly. Always
check the TPMS malfunction telltale after replacing one or more tires or wheels on
your vehicle, to ensure that the replacement or alternate tires and wheels allow the
TPMS to continue to function properly.
NOTE:
Tire pressures change by approximately 1 psi (7 kPa) per 12° F (7° C) of air temperature
change. Keep this in mind when checking tire pressure inside a garage, especially in the
Winter. Example: If garage temperature is 68°F (20°C) and the outside temperature is
32°F (0°C), then the cold tire inflation pressure should be increased by 3 psi (21 kPa),
which equals 1 psi (7 kPa) for every 12°F (7°C) for this outside temperature condition.
CAUTION!
The TPMS has been optimized for the original equipment tires and wheels. TPMS
pressures and warning have been established for the tire size equipped on your
vehicle. Undesirable system operation or sensor damage may result when using
replacement equipment that is not of the same size, type, and/or style. Aftermarket
wheels can cause sensor damage. Do not use tire sealant from a can, or balance
beads if your vehicle is equipped with a TPMS, as damage to the sensors may result.
- 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. You may want to call an authorized dealer for service if
your vehicle overheats.
WHAT TO DO IN EMERGENCIES
131

IF YOUR ENGINE OVERHEATS
• In any of the following situations, you can reduce the potential for overheating bytaking the appropriate action.
• On the highways — slow down.
• In city traffic — while stopped, place the transmission in NEUTRAL, but do not increase 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.

Once the engine is started, remove the jumper cables in the reverse sequence:
• Disconnect the negative(-)jumper cable from the engine ground of the vehicle
with the discharged battery.
• Disconnect the negative end (-)of the jumper cable from the negative (-)post of
the booster battery.
• Disconnect the opposite end of the positive (+)jumper cable from the positive (+)
post of the booster battery.
• Disconnect the positive (+)end of the jumper cable from the positive (+)post of
the discharged vehicle.
• If frequent jump-starting is required to start your vehicle you should have the battery and charging system inspected at your authorized dealer.
CAUTION!
• Do not use a portable battery booster pack or any other booster source with a
system voltage greater than 12 Volts or damage to the battery, starter motor,
alternator or electrical system may occur.
• Failure to follow these procedures could result in damage to the charging system of the booster vehicle or the discharged vehicle.
•
Accessories that can be plugged into the vehicle power outlets draw power from
the vehicle’s battery, even when not in use (i.e., cellular phones, etc.). Eventually,
if plugged in long enough, the vehicle’s battery will discharge sufficiently to
degrade battery life and/or prevent the engine from starting.
WARNING!
• When temperatures are below the freezing point, electrolyte in a discharged battery 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.

CAUTION!
• Mixing of engine coolant (antifreeze) other than specified Organic AdditiveTechnology (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.
E-85 Flexible Fuel – 3.6L/4.7L Engine Only
CAUTION!
Only vehicles with the E-85 fuel filler door label or a yellow gas cap can operate on
E-85.

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.
