System Operation
Electrical power for the charge air coolant pump is supplied from the intercooler water pump relay in the power distribution box.
When the intercooler water pump relay is energized, it connects power from the battery, via the BJB (battery junction box)
and CJB (central junction box), to the charge air coolant pump. Operation of the intercooler water pump relay is controlled by
the ECM (engine control module). The intercooler water pump relay is energized continuously while the ignition is in power
mode 6.

When the charge air coolant pump is running, coolant flows from the pump outlet through the charge air coolers, the charge air
radiator and back to the pump inlet. Supercharger Cooling Flow Diagram

1 Coolant outlet connection 2 Coolant inlet connection 3 Electrical connector The charge air coolant pump is an electric pump attached to the RH (right-hand) side of the charge air radiator. Hoses connect
the inlet of the charge air coolant pump to the charge air radiator, and the outlet to the charge air coolers. An electrical
connector provides the interface between the motor of the charge air coolant pump and the vehicle wiring. www.JagDocs.com

The charge air radiator is installed in
the cooling module, in front of the A/C (air conditioning) condenser. Brackets on the end tanks attach the charge air radiator to
the front of the engine cooling system radiator.

The RH end tank incorporates the coolant inlet and outlet connections, and a connection for the hose to the engine cooling system. Hoses connect the inlet of the charge air radiator to the charge air coolers, and the outlet to the charge air coolant
pump.

CHARGE AIR COOLERS

A charge air cooler is installed in each intake manifold.

WARNINGS: Published: 11-May-2011

Do not smoke or carry lighted tobacco or open flame of any type when working on or near any fuel related components.
Highly flammable vapors are always present and may ignite. Failure to follow these instructions may result in personal injury.


Before any work is carried out on the fuel system, ground the vehicle to earth and maintain the ground connection until
the work is complete.


CAUTION: Before disconnecting or removing components, make sure the area around the joint faces and connections are
clean. Plug open connections to prevent contamination.


NOTE: Tighten the fuel rail high pressure fuel pump fuel line unions and fuel rail crossover pipe unions as it is instructed
in service manual.

Principles of Operation

For a detailed description of the fuel charging and controls system and operation, refer to the relevant Description and
Operation section of the workshop manual. REFER to:

Fuel Charging and Controls (303-04D Fuel Charging and Controls - V8 5.0L Petrol, Description and Operation), Fuel Charging and Controls (303-04D Fuel Charging and Controls - V8 5.0L Petrol, Description and Operation), Fuel Charging and Controls (303-04D Fuel Charging and Controls - V8 5.0L Petrol, Description and Operation), Fuel Charging and Controls (303-04E Fuel Charging and Controls - V8 S/C 5.0L Petrol, Description and Operation), Fuel Charging and Controls (303-04E Fuel Charging and Controls - V8 S/C 5.0L Petrol, Description and Operation), Fuel Charging and Controls (303-04E Fuel Charging and Controls - V8 S/C 5.0L Petrol, Description and Operation).
Inspection and Verification


CAUTION: Diagnosis by substitution from a donor vehicle is NOT acceptable. Substitution of control modules does not
guarantee confirmation of a fault and may also cause additional faults in the vehicle being checked and/or the donor vehicle.


NOTE: Check and rectify basic faults before beginning diagnostic routines involving pinpoint tests.

1. Verify the customer concern.
2. Visually inspect for obvious signs of mechanical or electrical damage.

Accessory Drive - V8 S/C 5.0L Petrol - Accessory Drive - Overview
Description and Operation

OVERVIEW

The accessory drive is a belt system powered by a pulley attached to the front of the crankshaft. The crankshaft pulley, which
incorporates a torsional vibration damper, drives two drive belts. An automatic belt tensioner in each belt run maintains the
drive belt at the correct tension. Together with idler pulleys, the belt tensioners also guide the drive belts clear of obstructions
and set the correct 'wrap-around' of the accessory component drive pulleys to ensure a slip-free drive.

PRIMARY DRIVE BELT
The primary drive belt is a six-ribbed poly-V belt that drives the:
Coolant pump
Power steering pump
A/C (air conditioning) compressor
Generator.

SECONDARY DRIVE BELT

The secondary drive belt is an eight-ribbed poly-V belt that drives the SC (supercharger).

BELT TENSIONERS

Each belt tensioner consists of an idler pulley on the end of a spring loaded pivot arm. The pivot arms can be turned manually
for removal and installation of the drive belts.
Each belt tensioners is calibrated to automatically maintain the correct tension in the related drive belt.
