This also appears to be the standard fan setup on Diesel LR2's. "Someone" said something about Land Rover Engineers. Heh. The fan unit is made by Ford.

 

I don't recall being made aware of this dual fan option when I purchased my new 08 LR2. Sometimes these upgraded components are part of a towing package, but I don't recall a towing package option, either. Maybe I wasn't paying attention, or these options came after my purchase.

 

Not clear on what you are cautioning against. Do you mean that the intake manifold should be removed to get access to the fan, and not try to wiggle it out to the side?

 

Yup.

Remove the manifold or remove the front bumper radiator etc.

Removing the fan assembly only is possible but not fun. (ask me how I know)

Good luck

Some options were available in different markets. (i.e. outside of the US)

I am not sure where the dual fan was standard for the 3.2 maybe the Middle East, Africa and Australia. (Hot Markets)

It may have been possible to get the dual fan upgrade installed by the dealer as well as the extra cooling for the transmission fluid but I don't know how this was done.


If we ordered our vehicles like a lot of other countries then I suspect that you could get what you want but in the US we tend to buy what the dealer ordered.

Good luck

Paul

PS I just took delivery of a vehicle that I ordered and I got it exactly as I wanted it. But I had to wait a while for it to arrive. Note: its not a LAND ROVER and obviously not a LR2 so that is all that I will say about that......back to the LR2

 

TWIN ELECTRIC FAN ASSEMBLY

A twin electric fan assembly is mounted to the fan shroud and attached to the rear of the radiator. The fans draw air
through the radiator to regulate the coolant temperature, and provide cooling air through the engine compartment.
The fans are operated by the fan control module that receives a 0 to 100% Pulse Width Modulation (PWM) frequency signal
from the ECM. The ECM varies the PWM signal based on inputs from various sensors. The fan control module uses the PWM
signal to determine the required output voltage to the 2 cooling fan motors.

For additional information, refer to: Electronic Engine Controls - 2.2L Diesel (303-14 Electronic Engine Controls - 2.2L
Diesel, Description and Operation).

Following certain engine operating conditions and with the ignition switched off, the fans will continue to operate under
the control of the ECM to maintain engine cooling.

----------------------

The temperature of the cooling system is constantly monitored by the ECM via the ECT sensor signal. The ECM uses the
ECT signal to control operation of the cooling fans, and to adjust engine fueling. The ECM also operates the fans in
response to inputs from the automatic transmission oil temperature sensor, Air Conditioning (A/C) system control switch,
and the A/C pressure sensor. For additional information, refer to: Electronic Engine Controls - 2.2L Diesel (303-14
Electronic Engine Controls - 2.2L Diesel, Description and Operation).

For additional information, refer to: Air Conditioning (412-01 Climate Control, Description and Operation).
The cooling fan speed is also influenced by vehicle road speed. The ECM adjusts the speed of the cooling fans to
compensate for the ram air effect, using the CAN bus road speed signal received from the Anti-Lock Brake System (ABS)
module.

When the engine is shut down, the coolant temperature and volume decrease. The thermostat starts to close as the
coolant temperature decreases to 89°C (192°F), and is fully closed at 81°C (178°F). The coolant level within the reservoir
decreases as coolant is drawn from the reservoir to replenish the system.

Following engine shut down when the coolant pump is stationary, the ECM may continue to operate the cooling fans for a
pre-determined period to maintain engine cooling.

One fuse in the engine compartment fuse box covers both fans (F3, 80 AMP).

Both the single and dual fan units have a single controller that operates both fans. On single radiator units there is nothing connected to the second socket. There doesn't seem to be any mention of any required programming. The module apparently detects the presence of the 2nd fan automagically.
