Durango 2WD V8-5.7L Hybrid (2009)
Power Steering Fluid: Description and Operation
POWER STEERING FLUID
There are two types of power steering systems used on this vehicle. The conventional belt driven power steering pump system as well as an Electric
Power Steering (EPS) pump system. The EPS pump is used on the 5.7L Hybrid Electric Vehicle (HEV) while the conventional system is used on all
other vehicles.
BELT DRIVEN PUMP (CONVENTIONAL)
Mopar(R) ATF +4, Automatic Transmission Fluid is required in the power steering system. Substitute fluids can induce power steering system
failure.Mopar(R) ATF +4, Automatic Transmission Fluid when new is red in color. The ATF is dyed red so it can be identified from other fluids used in
the vehicle such as engine oil or antifreeze. The red color is not permanent and is not an indicator of fluid condition. As the vehicle is driven, the ATF
will begin to look darker in color and may eventually become brown. This is normal. ATF+4 also has a unique odor that may change with age.
Consequently, odor and color cannot be used to indicate the fluid condition or the need for a fluid change.
EPS PUMP (5.7L HEV)
The power steering system is filled at the factory with Pentosan CHF 11S. If necessary, use Mopar(R) hydraulic fluid, part number 05127381AA.
Steering noise and reduced component life may result if an unapproved fluid is used.
