DISCUSSION:
Chrysler Corporation LLC. has released a new engine coolant for the 2013 model year
vehicles and beyond, for all engine applications except the ones listed in the note above.
This new coolant is an Organic Additive Technology (OAT) (Fig. 1). OAT coolants have a
service interval of 10 years or 150,000 miles. For heavy duty truck and extreme duty cycle
applications refer to the Service Information or Owner's Manual for proper maintenance
schedules.
CAUTION: Vehicle Damage may occur if dissimilar coolants are mixed!
Coolants of different technologies are not compatible nor interchangeable (OAT, HOAT or
IAT).
Mixing these coolants could result in:
• accelerated corrosion within the engine and cooling systems.
• the coolant having an ammonia smell.
• debris (particles) floating in the coolant.
Further inspection by the technician may find corrosion in the system. This could show up
as aluminum pipes turning black in the coolant system, engine overheat, or leaks in the
coolant system.
NOTE: If OAT (MOPAR P/N 68163848AA Purple) has been Mixed with HOAT (MOPAR
P/N 68048953AB Pink Or Factory Fill HOAT Orange (Fig. 2) or (Fig. 3)) or any
other coolants have been mixed, it will be necessary to flush the cooling
system.
