2019 Ram 1500 coolant

Operating Tips
NOTE:Refer to the chart at the end of this section for
suggested control settings for various weather conditions.
Summer Operation
The engine cooling system must be protected with a
high-quality antifreeze coolant to provide proper corrosion
protection and to protect against engine overheating. OAT
coolant (conforming to MS.90032) is recommended.
Winter Operation
To ensure the best possible heater and defroster perfor-
mance, make sure the engine cooling system is functioning
properly and the proper amount, type, and concentration
of coolant is used. Use of the Air Recirculation mode
during Winter months is not recommended, because it may
cause window fogging.
Vacation/Storage
Before you store your vehicle, or keep it out of service (i.e.,
vacation) for two weeks or more, run the air conditioning
system at idle for about five minutes, in fresh air with the
blower setting on high. This will ensure adequate system
lubrication to minimize the possibility of compressor dam-
age when the system is started again.
Window Fogging
Vehicle windows tend to fog on the inside in mild, rainy,
and/or humid weather. To clear the windows, select De-
frost or Mix mode and increase the front blower speed. Do
not use the Recirculation mode without A/C for long
periods, as fogging may occur.
CAUTION!
Failure to follow these cautions can cause damage to
the heating elements:
• Use care when washing the inside of the rear win-
dow. Do not use abrasive window cleaners on the
interior surface of the window. Use a soft cloth and a
mild washing solution, wiping parallel to the heat-
ing elements. Labels can be peeled off after soaking
with warm water.
• Do not use scrapers, sharp instruments, or abrasive
window cleaners on the interior surface of the win-
dow.
• Keep all objects a safe distance from the window.

charged. If the pointer moves to either extreme left or
right and remains there during normal driving, the
electrical system should be serviced.
NOTE: In vehicles equipped with Stop/Start, a reduced
voltage may be present during an Autostop.
3. Instrument Cluster Display
•When the appropriate conditions exist, this display
shows the instrument cluster display messages. Refer
to “Instrument Cluster Display” in “Getting To Know
Your Instrument Panel” for further information.
4. Oil Pressure Gauge •The pointer should always indicate the oil pressure
when the engine is running. A continuous high or low
reading under normal driving conditions may indicate
a lubrication system malfunction. Immediate service
should be obtained from an authorized dealer.
NOTE: In vehicles equipped with Stop/Start, an oil pres-
sure indication of zero is normal during an Autostop. 5. Speedometer
•Indicates vehicle speed.
6. Fuel Gauge •The pointer shows the level of fuel in the fuel tank
when the ignition is in the ON/RUN position.
•
The fuel pump symbol points to the side of the
vehicle where the fuel door is located.
7. Temperature Gauge
•The gauge pointer shows engine coolant temperature.
The pointer positioned within the normal range indi-
cates that the engine cooling system is operating
satisfactorily.
• The gauge pointer will likely indicate a higher tem-
perature when driving in hot weather, up mountain
grades, or when towing a trailer. It should not be
allowed to exceed the upper limits of the normal
operating range.

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. If you decide to look
under the hood yourself, see “Servicing And Mainte-
nance.” Follow the warnings under the Cooling System
Pressure Cap paragraph.
CAUTION!
Driving with a hot engine cooling system could dam-
age your vehicle. If the temperature gauge reads “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 the
“H,” turn the engine off immediately and call an
authorized dealer for service.
