Dodge Challenger SRT 392 2015 Operating Information Manual page 272

WARNING! (Continued)
• You or others can be badly burned by hot
engine coolant (antifreeze) or steam from
your radiator. If you see or hear steam
coming from under the hood, do not open
the hood until the radiator has had time to
cool. Never try to open a cooling system
pressure cap when the radiator is hot.
Coolant Checks
Check the engine coolant (antifreeze) protec-
tion every 12 months (before the onset of
freezing weather, where applicable). If the en-
gine coolant (antifreeze) is dirty, the system
should be drained, flushed, and refilled with
fresh OAT coolant (conforming to MS.90032) by
an authorized dealer. Check the front of the A/C
condenser for any accumulation of bugs,
leaves, etc. If dirty, clean by gently spraying
water from a garden hose vertically down the
face of the condenser.
Check the coolant recovery bottle and/or the
supercharger coolant recovery
equipped with the 6.2L Supercharged engine)
tubing for brittle rubber, cracking, tears, cuts,
and tightness of the connection at the bottle and
radiator. Inspect the entire system for leaks.
With the engine at normal operating tempera-
ture (but not running), check the cooling system
pressure cap for proper vacuum sealing by
draining a small amount of coolant from the
radiator drain cock. If the cap is sealing prop-
erly, the engine coolant (antifreeze) 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
NOTE:
Some vehicles require special tools to add
coolant properly. Failure to fill these sys-
tems properly could lead to severe internal
engine damage. If any coolant is needed to
be added to the system please contact your
local authorized dealer.
If the engine coolant (antifreeze) is dirty or
contains visible sediment, have an authorized
dealer clean and flush with OAT coolant (anti-
bottle (if
freeze) (conforming to MS.90032).
NOTE:
If equipped with the 6.2L Supercharged en-
gine the intercooler must be vacuum
flushed and filled. If any coolant is needed to
be added to the system please contact your
local authorized dealer.
Refer to the "Service and Warranty Handbook"
for the proper maintenance intervals.
Selection Of Coolant
Refer to "Fluids, Lubricants, and Genuine Parts"
in "Maintaining Your Vehicle" for further informa-
tion.
CAUTION!
• Mixing of engine coolant (antifreeze) other
than specified Organic Additive Technol-
ogy (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
