radiator RAM CHASSIS CAB 2016 User Guide

The cap should be inspected and cleaned if there is any
accumulation of foreign material on the sealing surfaces.
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 en-
gine damage may result.
Disposal Of Used Engine Coolant
Used ethylene glycol-based engine coolant (antifreeze) is
a regulated substance requiring proper disposal. Check with your local authorities to determine the disposal
rules for your community. To prevent ingestion by ani-
mals or children, do not store ethylene glycol-based
engine coolant (antifreeze) in open containers or allow it
to remain in puddles on the ground. If ingested by a child
or pet, seek emergency assistance immediately. Clean up
any ground spills immediately.
Checking Coolant Level — 6.4L Engine
The level of the coolant in the pressurized coolant bottle
should be between the “MIN” and “MAX” range on the
bottle when the engine is cold.
The radiator normally remains completely full, so there is
no need to remove the cap unless checking for coolant
freeze point or replacing engine coolant (antifreeze).
Advise your service attendant of this. As long as the
engine operating temperature is satisfactory, the coolant 7MAINTAINING YOUR VEHICLE 591

bottle need only be checked once a month. When addi-
tional engine coolant (antifreeze) is needed to maintain
the proper level, it should be added to the coolant bottle.
Do not overfill.
Points To Remember
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 nor-
mally a result of moisture from rain, snow, or high
humidity accumulating on the radiator and being vapor-
ized when the thermostat opens, allowing hot engine
coolant (antifreeze) to enter the radiator.
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.90032) and distilled water for proper corrosion
protection of your engine which contains aluminum
components.
• 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.592 MAINTAINING YOUR VEHICLE

1. Open the hood.
2. Disconnect and isolate the negative battery cable.
3. Remove the six plastic push-in fasteners that secure
the upper radiator seal to the grille support and both
fender ledges.
4. Remove the two plastic push-in rivets that secure the
upper radiator seal to the radiator.
5. Remove the upper radiator seal from the vehicle.
6. Remove the two headlamp assembly attachment
screws. 7. Reach into the front wheel house ahead of the front
wheel, remove the fastener, and lift the cover over the
access hole in the front of the wheel house splash
shield. Access to the rear of the lamp can be gained
through this access hole. Headlamp Assembly Attachment Screw Locations

CAUTION!• Mixing of engine coolant (antifreeze) other than
specified Organic Additive Technology (OAT) en-
gine coolant (antifreeze), may result in engine
damage and may decrease corrosion protection.
Organic Additive Technology (OAT) engine cool-
ant is different and should not be mixed with
Hybrid Organic Additive Technology (HOAT) en-
gine coolant (antifreeze) or any “globally compat-
ible” 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.90032), by an au-
thorized dealer as soon as possible. (Continued) CAUTION! (Continued)• 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 (an-
tifreeze) is not recommended.628 MAINTAINING YOUR VEHICLE
