Replace at 24,000 miles unless previously replaced during
inspection.
( 5) - Replace coolant at 36,000 miles or 36 months whichever occurs
first. Replace coolant at 36 months regardless of mileage. After
first coolant change, replace coolant every 24 months or 30,000
miles thereafter.
( 6) - If equipped with EGR valve, clean EGR passages when replacing
EGR valve.
( 7) - Inspect and replace as necessary. Replace PCV valve at 60,000

Relief Pressure Test
1) Close gauge shutoff valve completely 3 times. Record
highest pressure attained each time. All 3 readings must be greater
than specifications and within 50 psi (3.5 kg/cm

) of each other. See
POWER STEERING PUMP PRESSURE TEST SPECIFICATIONS table. If pressures
are not as specified, replace pump. See POWER STEERING PUMP (GASOLINE)\
or VACUUM/POWER STEERING PUMP (DIESEL) under REMOVAL & INSTALLATION.
CAUTION: DO NOT hold steering wheel against stops more than 4 seconds,
or pump damage may result.
2) Open test valve and turn steering wheel to left and right
stops. Record highest pressure attained at each stop. If output
pressures are not equal against each stop, gear is leaking internally
and must be replaced. See STEERING GEAR under REMOVAL & INSTALLATION.
Shut off engine, remove test gauge, and connect pressure hose.

FLUID TYPE
CAUTION: DO NOT use Automatic Transmission Fluid (ATF).
Use Mopar Power Steering Fluid (4318055).
FLUID LEVEL CHECK
Check fluid level with engine cold and not running. Remove
fluid level dipstick on pump reservoir. Dipstick should indicate FULL
COLD with fluid temperature of 70-80
F (21-27C). If needed, add fluid
through dipstick opening, and recheck. DO NOT overfill.
HYDRAULIC SYSTEM BLEEDING
Fill power steering pump reservoir to specified level. Start
engine and slowly turn steering wheel to left and right, but DO NOT
contact steering stops in either direction. Stop engine. Inspect
reservoir fluid level and add fluid if necessary. Bleeding process may
have to be repeated several times to completely purge all air from
system.
ADJUSTMENTS
POWER STEERING PUMP BELT
Vehicles are equipped with dynamic tensioner. No adjustment
is required.
