Cylinder Block Drain Plug
The coolant drain plug is on the rear left side of the cylinder block.
On vehicles that have a cold climate package (for example: vehicles that operate in conditions regularly below -30°C) a
cylinder block heater unit is installed instead of the drain plug (Refer to Figure 3).

Knock Sensors
Two knock sensors (1) are installed into the cylinder block on the inboard side of each of the two cylinder banks. The
electrical connector of each sensor is secured to th e left-hand engine cover bracket (Refer to Figure 4).
These piezo-electric sensors send inputs to the ECM to indicate the detection and location of detonation during
combustion.
Bedplate
This is a structural casting that is attached with bolts to the bottom
of the cylinder block t attach the crankshaft and to further
improve overall rigidity.
Main bearing clearance changes due to expansion are minimized
by means of iron inserts cast into the bedplate main bearing
supports.
Two hollow dowels align the bedplate with the cylinder block and
the joint is sealed by a continuous bead of sealant.

Engine Mountings
The engine is mounted at two points. At the front, on ea ch side of the engine, there is a mounting bracket with a
Hydramount mounted to the subframe.

Cylinder Heads
The cylinder heads are unique to each cylinder bank and are attached with deep seated bolts, to the cylinder block. Two
hollow dowels align each cylinder head with the cylinder block.
Each cylinder head gasket has a silicon beaded compos ite gasket with metal eyelets for the cylinder bores.
There are two overhead camshafts that operate four valves each cylinder with solid aluminium-alloy valve lifters. A steel
shim in the top of each lifter gives adjustment of the valve clearances.
Collets, valve collars and spring seats locate the valve springs on the intake and exhaust valves. Valve stem seals are part
of the spring seats.
Four 14mm diameter spark plugs are installed in recesses on the center-line of each cylinder head.
Inlet/Exhaust Manifolds
Intake air is filtered and passed through Mass Air Flow (MAF) meters. The air then passes through the throttle body into
the eight-branch inlet manifold.
