2010 JAGUAR XFR Radiator hose

Filling

1. Refer to: Radiator Splash Shield (501-02 Front End Body Panels, Removal and Installation).

2. Lower the vehicle.

3.
4. CAUTION: Anti-freeze concentration must be maintained at 50%.

Fill the cooling system, keeping coolant to the upper level mark of the
expansion tank until a steady stream of coolant is seen running from the
coolant hose bleed point.

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.
