NOTE: Always refer to appropriate engine overhaul article in the
ENGINES section for complete overhaul procedures and
specifications for the vehicle being repaired.
ROTOR-TYPE
Oil pump rotors must be marked for location prior to removal.
See Fig. 30 . Remove outer rotor and measure thickness and diameter.
Measure inner rotor thickness. Inspect shaft for scoring or wear.
Inspect rotors for pitting or damage. Inspect cover for grooving or
wear. Replace components if worn or damaged.

This Graphic For General Information Only
Measure outer rotor-to-body clearance. Replace pump assembly
if clearance exceeds specification. Measure clearance between rotors.
See Fig. 31 . Replace shaft and both rotors if clearance exceeds
specifications.

This Graphic For General Information Only
Install rotors in pump body. Position straightedge across
pump body. Using feeler gauge, measure clearance between rotors and
straightedge. Pump cover wear is measured using a straightedge and
feeler gauge. Replace pump if clearance exceeds specification.
GEAR TYPE
Oil pump gears must be marked for location prior to removal.
See Fig. 32 . Remove gears from pump body. Inspect gears for pitting
or damage. Inspect cover for grooving or wear.

appropriate.
LONG BLOCK ASSEMBLY INSPECTION
\
\
\
\
\
\
\
Condition Code Procedure
Internal component failure
(any component) ........ A ........... (1) Require repair or
replacement of the long
block assembly.
( 1) - It is Required that all other failure related components
be inspected for cause and condition. Additional components
or assemblies may be Suggested for repair or replacement
such as a water pump on a short block (reason code 4,
technician's recommendation based on substantial and
informed experience).
Example:
If there is a failed head gasket with an external coolant
leak, in addition to Requiring replacement of the head
gasket, inspection of the following for cause and
condition is Required: Block, Cooling System, Cylinder
Head. It may be Suggested that additional inspections be
performed, such as the other head gasket on a V-type
engine.
\
\
\
\
\
\
\
SHORT BLOCK ASSEMBLIES
NOTE: A Short Block Assembly is a cylinder block and all those
components contained within the limits of the block deck
or decks, the pan rail, the block rear face and the
timing cover (where fitted), including the crankshaft.
SHORT BLOCK ASSEMBLY INSPECTION
\
\
\
\
\
\
\
Condition Code Procedure
Any internal component
failure ................ A ........... ( 1) Require repair or
replacement of the short
block assembly.
( 1) - It is Required that all other failure related components
be inspected for cause and condition. Additional
components or assemblies may be Suggested for repair or

DESCRIPTION & OPERATION
WARNING: Deactivate air bag system before performing any service
operation. See AIR BAG RESTRAINT SYSTEMS article. Do not
apply electrical power to any component on steering column
without first deactivating air bag system. Air bag may
deploy.
Instrument cluster includes speedometer, fuel gauge and
temperature gauge. Fuel gauge has a built-in voltage limiter to keep
voltage supply to gauges at 7 volts. Some models may also have an
ammeter, oil pressure gauge, tachometer, voltmeter and/or turbo boost
pressure gauge. Oil pressure gauge uses full battery voltage.
Tachometer operates by pulse feed.

TROUBLE SHOOTING
FUEL/TEMPERATURE GAUGE NOT WORKING
Check for blown fuse, faulty voltage limiter and faulty
relay. Ensure sending unit connections are clean and tight. Test
sending unit for correct operation. Tighten connections in instrument
cluster.
SPEEDOMETER NOT WORKING
On mechanical-type speedometers, ensure speedometer cable is
properly connected and correctly routed. If speedometer pointer and/or
odometer still do not work, replace speedometer cable or speedometer
assembly.
On electric-type speedometers, check for faulty vehicle speed
sensor, input/output sensors or faulty circuit. For testing, see
