Diagnosis and Testing
Principle of Operation
For a detailed description of the engine cooling system and operation, refer to the relevant description and operation section of
the workshop manual. Engine Cooling, Section - 303-03
Inspection and Verification
WARNING: Moving parts can cause severe injury, keep clear of moving parts, never place your hands or any part of your
body near to moving parts
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
NOTES:
Check DDW for open campaigns. Refer to the corresponding bulletins and SSMs which may be valid for the specific
customer complaint and carry out the recommendations as required.
If the control module or a component is suspect and the vehicle remains under manufacturer warranty, refer to the
Warranty Policy and Procedures manual, or determine if any prior approval programme is in operation, prior to the installation
of a new module/component.
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

3. If an obvious cause for an observed or reported concern is found, correct the cause (if possible) before proceeding to
the next step
4. If the cause is not visually evident, verify the symptom and refer to the symptom chart, alternatively check for
diagnostic trouble codes (DTCs) and refer to the DTC Index

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

1 Pipe clip bracket (2 off) 2 Coolant outlet connection 3 Lower attachment bracket (2 off) 4 Coolant inlet connection 5 Upper attachment bracket (2 off) 6 Expansion hose connection (with engine cooling system) The charge air radiator is a cross flow type with an aluminum core and plastic end tanks. 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.
