Electric fans

Hi,

I understand that the D3 has an electric controlled Viscous fan...

I would like to get rid of the viscous fan, and install Electric SPAL fans...

can I use the contact of that Viscous controller for ON-OFF of the electric fans, or am I missing something? Embarassed

kind regards

Henry

don't know what happened with older vehicles... Embarassed

BUT have always changed viscous for electric fans on my previous cars, for crossing water+ more temp control Smile


AND the last vehicle was sold in bits and I kept the NEW spals so wanted to see if they would fit Smile

Got a second battery, so always power for the fans Smile

The viscous fan is extremely efficient. The electric side is PWM controlled - and not just from engine temperature ether, but also the AC. Mark.

When I made enquiries of Kenlowe, the electric fan replacement specialists, they advised me that they were unable to make an electric cooling fan for the D3 due to the complex wiring/sensors etc. associated with the EMS. LR technical were unwilling to assist them! Happiness is a warm ruck

I have it on very good authority that Kenlowe's claims that their electric (or any!) fans are more efficient than a correctly working viscous fan is rubbish. Mark.

I had a Kenlowe on my Defender . Worked very well , but draws about 30 A Shocked . This became a real issue when I was overlanding and needed to charge my aux batteries , as too much was going to the fan and not the batteries
