Engine serial number
The engine serial number (12 digits) and engine code (5 digits) are stamped on the exhaust side of the cylinder block,
parallel to the transmission clutch housing.
Engine Identification Plate
The engine identification plate is located on the cover of the timing cover. It contains the date and time of manufacture
and the engine part number.
CYLINDER BLOCK COMPONENTS
The main cylinder block components are:
The cylinder block
Piston cooling jets
Rear crankshaft oil seal and retainer
Connecting rods and pistons
Crankshaft Position (CKP) sensor
Starter motor
Generator
Coolant and vacuum pump
Power steering pump
High-pressure fuel pump
Coolant distribution manifold
Cylinder Block
The cylinders and crankcase are contained in the cylinder block, which is of single cast CGI construction with a hollow
beam structure. With this type of construction less material is required than for a conventional cast iron block,
therefore, reducing engine weight and length.
The cylinder bores are machined directly in the block.
Three different bore diameters are used in production to ensure very precise adjustment of the clearance between the
pistons and cylinders.
A turbocharger oil feed filter is located at number 1 journal to prevent debris from entering the turbocharger and
damaging the bearings.
Piston Cooling Jets
Item
Part Number
Description

-
Piston cooling jet
Jets located in the cylinder block provide piston and piston pin lubrication and cooling. These jets spray oil on to the
inside of the piston, the oil then flows through an internal wave shaped oil cooling channel to help cool each piston
crown.

Oil cooling channels
Lubrication oil is distributed through the cylinder block, via the main oil gallery and channels bored in the block, to all
critical moving parts. These channels divert oil to the main and big-end bearings via holes machined into the crankshaft.
