DSG-423 ENGINE

Lubrication System
The engine lubrication system consists of:
• Oil pan.
• Oil pump screen cover and tube.
• Oil pump.
• Oil filter.
• Passageways in the cylinder block, crankshaft,
camshaft and cylinder head.
The oil pan is pressure-cast aluminum and serves as
both an oil reservoir and engine bottom cover. The oil
pan has reinforcing ribs which strengthen the pan,
reduce engine noise transmission, and aid in oil cooling.
The oil pump is mounted to the engine block and is
driven by chain from the crankshaft. Oil cooling jets
spray to the underside of the piston skirt.
Drive Belt System
Engine accessories, such as the generator and water
pump, are driven by a single serpentine belt. Tension is
automatically adjusted by a tensioner.
Ignition System
The ignition used on the 2.3L engine is an Electronic
Distributorless Ignition System (EDIS). Individual
ignition coils are located directly above each spark plug
and are used to ignite the fuel in the cylinders.
Refer to Section 03 of this manual for more information
on the ignition system.
Fuel System
The fuel system includes a remote mounted electric fuel
pump. The pump regulates and maintains fuel flow,
through an in-line fuel filter to the electronic actuator
mounted on the intake manifold.
The engine can be adapted for dry fuel use. Refer to
Section 04 of this manual for more information on the
fuel system.
