1 General Information
The HFV6 engine features a closed vee, deep skirt die cast aluminium cylinder block with cast iron cylinder liners,
internally balanced crankcase, full length wa ter jackets and six bolt main bearing caps.
The cylinders are arranged in two banks of three with a 60 degree included angle between the two banks.
The right-hand bank of cylinders consists of number 1-3-5
cylinders and the left-hand bank of cylinders consists of
number 2-4-6.
The engine firing order is 1-2-3-4-5-6.
Each aluminium cylinder head is fitted with hardened valve
seats and four valves per cylinder: two intake and two
exhaust.
The valves are operated by two camshafts (DOHC) per
cylinder bank, one each for intake and exhaust valves.
The crankshaft is manufactured from forged steel. A reluctor
wheel is pressed in place onto the rear of the crankshaft for
the crankshaft position sensor.
The connecting rods are m anufactured from powdered
metal and the rod cap is separ ated during the manufacturing
process using the fractured me thod. This creates a stronger,
visually seamless rod to cap union.
Figure 6A1 – 1
MY06 Update
Throughout this Section, reference is made to 'MY06 Update' or 'Excluding MY06 Update'.
Vehicles manufactured post 14th Marc h 2007 are fitted with an updated version of the HFV6 engine. This engine
features a different timing chain, and as a result different sprocket teeth. This change also introduces the use of a new
special tool to assist in the serviceab ility of replacing the engine timing components.
All service procedures and descriptions specific to this update variation are qualified as 'MY06 Update'.
1.1 WARNING, CAUTION and NOTES
This Section contains various WARNING S, CAUTIONS and NOTE statements that y ou must observe carefully to reduce
the risk of death or injury during servic e, repair procedures or vehicle operation. Incorrect service or repair procedures
may damage the vehicle or cause operat ional faults. WARNINGS, CAUTION and NOTE statements are not exhaustive.
HOLDEN LTD can not possibly warn of a ll the potentially hazardous consequences of failure to follow these instructions.
Definition of WARNING, CAUTION and NOTE Statements
Diagnosis and repair procedures in this Section contain both general and specific WARNING, CAUTION and NOTE
statements. HOLDEN LTD is dedicated to the presentation of service information that helps the technician to diagnose
and repair the systems necessary for proper operation of the vehicle. Certain procedures may present a hazard to the
technician if they are not followed in the reco mmended manner. WARNING, CAUTION and NOTE statements are
designed to help prevent these hazards from o ccurring, but not all hazards can be foreseen.
WARNING defined
A WARNING statement immediately precedes an operating procedure or maint enance practice which, if not correctly
followed, could result in death or injury . A WARNING statement alerts you to ta ke necessary action or not to take a
prohibited action. If a WARNING statement is ignored, the following consequences may occur:
• Death or injury to the technician or other personnel working on the vehicle,
• Death or injury to other people in or near the workplace area, and / or
• Death or injury to the driver / or passenger(s) of the vehicle or other people, if the vehicle has been improperly
repaired.
CAUTION defined
A CAUTION statement immediately prec edes an operating procedure or maintenance practice which, if not correctly
followed, could result in damage to or destruction of equi pment, or corruption of data. If a CAUTION statement is
ignored, the following consequences may occur:
• Damage to the vehicle,
• Unnecessary vehicle repairs or component replacement,
