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 water 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 manufactured from powdered 
metal and the rod cap is separated during the manufacturing 
process using the fractured method. This creates a stronger, 
visually seamless rod to cap union.

MY06 Update 

Throughout this Section, reference is made to 'MY06 Update' or 'Excluding MY06 Update'. 

Vehicles manufactured post 14th March 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 serviceability of replacing the engine timing components. 

All service procedures and descriptions specific to this update variation are qualified as 'MY06 Update'.
