Hi not sure about the 300TDi but I've been running my 200 defender without a fan for well over a year now..Only time she gets hot is prolonged slow speeds (2nd gear low box) and high revving such as recovering something..

Hi
I ran mine without a fan for 2 years only refitting it for laning .

However I have just fitted an aircon push fan in front of the rad on a switch and a pull fan behind the rad on another switch both taken from a vectra 130sri both are slimline and are two speed :D and as they are plastic and worth nothing the scrap guy gave them to me foc... :D :D

I don't know about mpg but the pickup is much better  :twisted:

Well removed the fan, or should i say it fell off......

Went for quick run tonight and no apparent problems, biggest test will be tomorrow queing in to Gosport for 45 mins.

Fingers crossed

Also took of the fan cowling off, now here is a question for you....

Would the cowling restrict the amont of air flow through the radiator and intercooler, almost acting as a damper...... i know the fan draws air through the radiator but surely this arrangement must be restrictive to air flow.

Any thoughts.  Mine seems to run more freely but it maybe just me wishing it runs freely.....

fish:
I was thinking about removing the standard fan, but not sure if the gain in power form removing it would be offset by the loss of intercooler efficiency at lower speeds.  I suppose the best solution would be to have an electric fan on the intercooler running all the time with one on the rad with a manual switch.
