Chrysler 2013 300 SRT - Owner Manual - Manual (Page 496)

With the engine at normal operating temperature (but
not running), check the cooling system pressure cap for
proper vacuum sealing by draining a small amount of
engine coolant (antifreeze) from the radiator drain cock.
If the cap is sealing properly, the engine coolant (anti-
freeze) will begin to drain from the coolant recovery
bottle. DO NOT REMOVE THE COOLANT PRESSURE
CAP WHEN THE COOLING SYSTEM IS HOT.
Cooling System – Drain, Flush, And Refill
If the engine coolant (antifreeze) is dirty or contains visible
sediment, clean and flush with OAT coolant (antifreeze)
that meets the requirements of Chrysler Material Standard
MS-12106.
Refer to the “Maintenance Schedule” for the proper
maintenance intervals.
Selection Of Coolant
Refer to “Fluids, Lubricants, and Genuine Parts” in “Main-
taining Your Vehicle” for further information.
CAUTION!
• Mixing of engine coolant (antifreeze) other than speci-
fied Organic Additive Technology (OAT) engine cool-
ant (antifreeze), may result in engine damage and may
decrease corrosion protection. Organic Additive Tech-
nology (OAT) engine coolant is different and should
not be mixed with Hybrid Organic Additive Technol-
ogy (HOAT) engine coolant (antifreeze) or any “glob-
ally compatible” coolant (antifreeze). If a non-OAT
engine coolant (antifreeze) is introduced into the
cooling system in an emergency, it should be flushed
with OAT coolant and replaced with the specified
OAT engine coolant (antifreeze) as soon as possible.
