STANDARD PROCEDURE
POWER STEERING FLUID LEVEL CHECKING
WARNING: FLUID LEVEL SHOULD BE CHECKED WITH THE ENGINE OFF TO PREVENT PERSONAL INJURY
FROM MOVING PARTS.
CAUTION: THIS SYSTEM REQUIRES THE USE OF HYDRAULIC SYSTEM / POWER STEERING FLUID WHICH
MEETS DAIMLER CHRYSLER SPECIFICATION MS-10838, SUCH AS MOPAR PART NUMBER 05142893AA, OR
EQUIVALENT, DO NOT MIX POWER STEERING FLUID TYPES. DAMAGE MAY RESULT TO THE POWER
STEERING PUMP AND SYSTEM IF ANY OTHER FLUID IS USED, AND DO NOT OVERFILL.
The power steering fluid level can be viewed on the dipstick attached to the filler cap. There are two ranges listed
on the dipstick, COLD and HOT. Before opening power steering system, wipe the reservoir filler cap free of dirt and
debris. Remove the cap and check the fluid level on its dipstick. When the fluid is at normal ambient temperature,
approximately 21°C to 27°C (70°F to 80°F), the fluid level should read between the minimum and maximum area of
the cold range. When the fluid is hot, fluid level is allowed to read up to the highest end of the HOT range. Only add
fluid when the vehicle is cold.
Use only hydraulic system / power steering fluid which meets Daimler Chrysler specifications MS - 10838
Mopar Part number 05142893AA or equivalent Do not overfill the power steering system.
