cooling Ram 3500 Chassis Cab 2019 Owner's Guide

TECHNICAL SPECIFICATIONS 485
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.
