Dodge Challenger SRT 392 2015, Operating Information Manual

Cooling System Pressure Caps
The cap must be fully tightened to prevent loss
of engine coolant (antifreeze), and to ensure
that engine coolant (antifreeze) will return to the
radiator from the coolant recovery tank.
The cap should be inspected and cleaned if
there is any accumulation of foreign material on
the sealing surfaces.
NOTE:
Be sure you do not mix the engine coolant
system pressure cap with the intercooler
system pressure cap these caps are not
interchangeable.
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.

WARNING! (Continued)
•
Do not use a pressure cap other than the
one specified for your vehicle. Personal
injury or engine damage may result.
Disposal Of Used Engine Coolant
Used ethylene glycol-based engine coolant (an-
tifreeze) is a regulated substance requiring
proper disposal. Check with your local authori-
ties to determine the disposal rules for your
community. To prevent ingestion by animals or
children, do not store ethylene glycol-based
engine coolant 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 imme-
diately.
Coolant Level
The coolant bottle provides a quick visual
method for determining that the coolant level is
adequate. With the engine OFF and cold, the
level of the coolant in the bottle should be
between the ranges indicated 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 tem-
perature 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 bottle. Do not overfill.
Points To Remember
NOTE:
When the vehicle is stopped after a few
miles/kilometers of operation, you may ob-
serve vapor coming from the front of the
engine compartment. This is normally a re-
sult of moisture from rain, snow, or high
humidity accumulating on the radiator and
being vaporized when the thermostat opens,
allowing hot engine coolant (antifreeze) to
enter the radiator.
