Only problem in changing to electric fan is mounting the thermal switch for the fan. On cars with EGR there is a thermally operated vacuum switch. I believe that if it is removed and replaced by a thermal switch that will do the job nicely (I will be trying it soon myself). I obtained a 960 fan unit which comes with twin relay. I will use the thermal switch to energise the lower fan speed and wire an override switch on the dash for the higher speed. Each speed will have a lamp to tell you what is happening. A steady one for low speed and a flashing one for high speed. When fitted I will be able to remove ( I have a D24 TIC diesel) the viscous coupling, fan blades and bearing mount and with a shorter drive belt for the alternator I should be in business.

All the best, Peter
