2018 Ram 4500 Chassis Cab engine coolant

CAUTION!
• Mixing of engine coolant (antifreeze)other than specified Organic Additive
Technology (OAT) engine coolant (anti-
freeze), may result in engine damage
and may decrease corrosion protection.
Organic Additive Technology (OAT) en-
gine coolant is different and should not
be mixed with Hybrid Organic Additive
Technology (HOAT) engine coolant (anti-
freeze) 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 cool-
ant (conforming to MS.90032), by an
authorized dealer as soon as possible.
• Do not use water alone or alcohol-based
engine coolant (antifreeze) products. Do
not use additional rust inhibitors or an-
tirust products, as they may not be com-
patible with the radiator engine coolant
and may plug the radiator.
CAUTION!
• This vehicle has not been designed foruse with propylene glycol-based engine
coolant (antifreeze). Use of propylene
glycol-based engine coolant (antifreeze)
is not recommended.
