VALVE CLEARANCE
Gasoline Models
All engines are equipped with hydraulic lifters. No
adjustments are required.
5.9L Diesel (Ram Pickup)
Valve adjustment is recommended every 150 months or 150,000
miles during normal service, every 135,000 miles during severe
service. Severe service is described as frequent short trip operation
of less than 5 miles, long periods of engine idling, trailer towing,
police, taxi, local delivery service, or operating in dusty or
excessively hot conditions. See VALVE CLEARANCE SPECIFICATIONS
(DIESEL) table.

REMOVAL & INSTALLATION
CAUTION: When battery is disconnected, vehicle computer and memory
systems may lose memory data. Driveability problems may exist
until computer systems have completed a relearn cycle. See
the COMPUTER RELEARN PROCEDURES article in GENERAL
INFORMATION before disconnecting battery.
POWER STEERING PUMP (GASOLINE)
WARNING: DO NOT attempt to remove power steering pump without removing
power steering pump belt. Personal injury or pulley damage
could result.
Removal
1) Disconnect and isolate negative battery cable. To remove
serpentine belt, rotate tensioner clockwise and hold in place, slide
belt from tensioner pulley. Place drain pan under pump. Disconnect and
cap hoses.
2) Remove bracket-to-engine block bolts. Remove pump, pulley
and mounting bracket as an assembly. To allow access to pump screws,
remove pump pulley. See PUMP PULLEY. Remove bracket-to-pump screws.
Installation
To install pump, reverse removal procedure. Fill and bleed
system. See HYDRAULIC SYSTEM BLEEDING under LUBRICATION.
VACUUM/POWER STEERING PUMP (DIESEL)
Removal
1) Disconnect negative battery cable. Place drip pan under
vacuum/power steering pump. Disconnect and cap power brake booster
hose at vacuum pump and hydraulic lines at power steering pump.
Disconnect oil pressure sending unit electrical connector. Remove
sending unit from engine block and plug hole in block. Disconnect and
cap oil feed line from bottom of vacuum pump.
2) Remove vacuum/power steering pump-to-engine block nuts and
bolts, and mounting bracket. Remove upper pump bolt and remove pump.
Drain fluid from steering pump reservoir. Remove gaskets from mounting
surfaces.
CAUTION: DO NOT damage internal vacuum pump oil seal when separating
steering pump from vacuum pump. See Fig. 5.
3) Remove steering pump-to-vacuum pump bracket bolts.
Carefully slide steering pump from bracket. Remove 2 pump body
spacers. See Fig. 5.
NOTE: Steering pump housing and spacers must mate completely with
vacuum pump bracket.
Installation
1) Install 2 pump body spacers and rotate drive gear until
steering pump and vacuum pump drive splines align. See Fig. 5.
Carefully install steering pump on vacuum pump bracket to prevent
damaging oil seal.
