coolant Ram 2500 2019 Owner's Guide

526 SERVICING AND MAINTENANCE
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 normally a result of mois-
ture 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.
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 (antifreeze)
needs to be added, the contents of the coolant expansion
bottle must also be protected against freezing.
• 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.
• Do not change the thermostat for Summer or Winter oper -
ation. If replacement is ever necessary, install ONLY the
correct type thermostat. Other designs may result in unsat -
isfactory engine coolant (antifreeze) performance, poor
gas mileage, and increased emissions.

Engine Oil – 6.4L For best performance and maximum protection under all
types of operating conditions, the manufacturer only
recommends full synthetic engine oils that meet the
American Petroleum Institute (API) categories of SN. The
manufacturer recommends the use of Pennzoil Ultra 0W-40
or equivalent Mopar engine oil meeting the requirements of
FCA Material Standard MS-12633 for use in all operating
temperatures.
Engine Oil Filter We recommend you use Mopar brand Engine Oil Filters.

TECHNICAL SPECIFICATIONS 573
CAUTION!
• Mixing of engine coolant (antifreeze) other than speci -
fied 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.90032), by an autho -
rized dealer as soon as possible.
• Do not use water alone or alcohol-based engine coolant (antifreeze) products. Do not use additional rust inhib -
itors or antirust products, as they may not be compat -
ible 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 (anti -
freeze) is not recommended.
