Defender 200Tdi Fan Cowling mystery

Hi,

Whilst putting my fan cowling back on the vehicle I realised that
someone has in the past taken an angle grinder to it (disc marks
visible) to remove probably the bottom 1/4 of the bit that wraps
around the fan blades.

The square bit that fits upto the rad/intercooler is all present.

Would this affect the cooling capability of the fan? It would
certainly slow the air flow down such that it wouldnt hit the engine
with as much force. Would this account for the engine constantly
reading about 2 needle widths higher than it should at operating
temperature?

I suspect it has been cut to allow removal without removing the fan
first? I cant think of any other reason why it would be cut.

Any other thoughts?

Anyone know the cost of replacement one???? Richard perhaps??


Thanks
Jon

The fan is not there to blow air over the engine !

It is there to draw air through the radiator. A much more efficient way
of cooling the engine.

I would not worry about your cowling .

I have removed the one on mine completely and it makes little
difference. The only time it got hot was when the rad was blocked. Then
the cowling may have made a small difference.

The reason for me removing mine is for ease of access in respect of
cleaning the rad and attending to the belts etc.

Prolly your stat is causing that, changed mine & it has run below centre on
the gauge ever since.

OK.

Cool, less expense!

Having replace the PAS belt from underneath tonight (cos i couldnt be
arsed to removed cowling again) I fully appreciate why you've taken it
off.

Out of interest are you using an electric fan or original via vicous
unit?

In the UK climate it's most likely not an issue.

I think you are right - but they can be got out with a good deal
of fiddling without cutting.

I've divided the one on the 300 TDi disco in half, vertically. Still stays
on the rad, but it can be removed without removing the fan. This is not
possible with the thing in one piece, AFAICT.

Yes. Each time you take the cowling off you have to take the top hose
off.

As I run a hydraulic winch there is one more belt on mine too.

I am using the original viscous fan, I did experiment with an electric
but as the car is only really used as an offroad toy the kenlow was not
reliable enough in adverse conditions.

The only time you need the fan on a tdi is at motorway speeds and when
towing. It became a bit of a pain stopping on the motorway and hitting
the fan with the handle of a screwdriver to get it to come on.

If you don't use yours in deep water then a kenlow should be fine.
