Service Precaution

WARNING: IF SO EQUIPPED WITH A

SUPPLEMENTAL RESTRAINT SYSTEM (SRS),

REFER TO THE SRS COMPONENT AND WIRING

LOCATION VIEW IN ORDER TO DETERMINE

WHETHER YOU ARE PERFORMING SERVICE ON

OR NEAR THE SRS COMPONENTS OR THE SRS

WIRING. WHEN YOU ARE PERFOMING SERVICE ON

OR NEAR THE SRS COMPONENTS OR THE SRS

WIRING, REFER TO THE SRS SERVICE

INFORMATION. FAILURE TO FOLLOW WARNINGS

COULD RESULT IN POSSIBLE AIR BAG

DEPLOYMENT, PERSONAL INJURY, OR

OTHERWISE UNNEEDED SRS SYSTEM REPAIRS.

CAUTION: Always use the correct fastener in the

proper location. When you replace a fastener, use

ONLY the exact part number for that application.

HOLDEN will call out those fasteners that require a

replacement after removal. HOLDEN will also call

out the fasteners that require thread lockers or

thread sealant. UNLESS OTHERWISE SPECIFIED ,

do not use supplemental coatings (Paints, greases,

or other corrosion inhibitors) on threaded fasteners

or fastener joint interfaces. Generally, such

coatings adversely affect the fastener torque and

the joint clamping force, and may damage the

fastener. When you install fasteners, use the correct

tightening sequence and specifications. Following

these instructions can help you avoid damage to

parts and systems.

General Description

Clutch

For 4JX1 (3.0L) engine models, the pull-type clutch is

employed. The pull-type clutch is disengaged by

pulling the release lever (release bearing) to disengage

the pressure plate.
