My 1988 300Tdi powered 110 has an electric fan fitted.....although temp rarely goes above half way on the gauge.
In a different vain, the girlfriends 1991 300Tdi powered 110 doesn't have a fan or electric fan and the temp never budges past half way....
Unless towing hard, off roading hard or tanking the carp out of it, a well sorted and maintained cooling system should be perfectly adequate to keep the engine temps wher ethey need to be....
That being said, it is nice to know you have some additional cooling capacity with a fan fitted!

I do have a viscous fan fitted. am i better sticking with it over a electric fan?
If you experience no problems and your cooling system is in fine fettle, there would be no advantage to removing it, aside from the tiny decrease in fuel consumption.
Many fit fans when they remove the VCF, as removing it will have a tiny affect on MPG, but want peace of mind that they have additional cooling ability when needed....
That is really the only advantage I can see....

That to my mind sounds very optimistic, can I ask where the info came from please?

Shame , I would be very surprised if it was the case. Was it maybe a sales blurb? If you do remember please let me know.
If it did work that way, then I would expect everyone and their dog to be changing their engines over to leccy fans as a cheap upgrade. You can spend a lot of money getting almost a 10% increase in power.

I have a Viscous fan on my 200 tdi , 110. It originally had a Viscous but It wasn't working as it should. I bought and fitted a Kenlowe electric fan as where I live it can go below -15C during the winter months. I thought it might improve warm up time and might improve the heating. It made no difference what so ever . I was told it would also improve MPG but I didn't notice any difference there either.
The Kenlowe worked perfectly. It was set on a thermostat and was automatically activated. I did a trip across Morocco with it and no problems. During the summer months here in France it might trip in two or three times a year. In Morocco it came on as and when needed. However I found myself always watching the temperature gauge to make sure it came on when needed.
When I replaced the rad I went back to a Viscous fan and I have no intention of going back to electric. A viscous fan does its job, you don't have to worry if you have a electrical problem. I just feel happier with the original design. Fitting an Electric fan in my opinion is not an up grade. Its just another unnecessary worry. If you do intend on going electric I can recommend Kenlow. It has been through sand storms where the sand gets everywhere. It has traversed rivers etc etc. without any problems. A viscous does exactly the same job and cost less and less likely to go wrong.
Save your money, or spend it on something else.

12 hp improvement! Holy moley that's nearly bobbling the power of me landy. Where can I get one.

Bloody predictive test. Bobbling, what does that even mean. Should be doubling.

Interesting vid,
Only thing I would say is that if you look closely at the vid although there is always a slight parasitic drain off, the delta between no fan and a viscous fan really starts to take effect at quite high RPM. The graphs they are using start at 3000RPM . I would like to see this test done with a 300tdi, at normal running RPM, to see what the difference would be. I still think a 12BHP improvement is used as a bit of a sales blurb with no real explanation given of what it really means.
Cheers

I felt uncomfortable without having a "real fan" initially but as I said it works as advertised. My old 2.5N/A d had overheating problems as the viscous fan failed, and went back to normal when replaced. I monitor the temperature constantly and have only had one spike, which I traced to low coolant...this went away when motor was topped up. Don't know where the fluid went as I was super careful when filling the system. Went so far as to fill system from a raised heater hose...to use as a high point.

unless you are going to wade water so deep that the fan will dip into the water (which implies flooding the inside to stop it floating) then I'd have said not.
My 200tdi 110 has a electric fan, I've had it 10 years plus in the UK, the fan has never come on in normal use. Only when sat at the MOT garage going nowhere getting warmed up for the emission test.
I have carried 1.2 tons (oops) in mid summer for 25 miles or driven 200 miles+ or towed a 1 ton yacht for 20 miles. Not a peep from the fan.
