Defender 200Tdi Fan Cowling mystery

Jul 01, 2005 7 Replies

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.

Would this account for the engine constantly

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

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.

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.

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.

It can definately stay as it is!!! Or if i feel adventurous I may start playing with fibre-glass and MDF!
