Another question!
« on: November 06, 2007, 11:24:21 »
I have put a 200tdi dico engine in my 90, and I have fitted a electric fan. Does anyone know, at what temp should the fan kick in, and any advice on what sender/switch I could use to get it to kick in at the correct temp.  :?

Fan should come on at 88degrees.
I use THIS to switch my fan & also overide the switch so it's constantly on  :wink:  8)

I also use Croytec switches  8)

id hope the fan would come on a bit later than that as the thermostat opens at 80,
my fan doesnt come on till 96 iirc

Not that I belive it's totally accurate, but the fan I fitted to Julie's TDi is set to 95 degrees too, otherwise it's coming on whilst I'm driving.

Remeber the stat starts to open at 88 deg, doesn't mean it won't get hotter.

Well you lot are doing well, I have just fitted the same X-Eng thermostat and the fan does not come on, ever :!:

The first thermostat was knackered, on the second one the low side comes on about 1 second before the high, that is in boiling water.

So either my water temperature is below 88 degrees and does not get any hotter or the thermostat is not calibrated to 88 degrees and is coming on at boiling point.

Simon at X-Eng said he tested the replacement unit, but no matter what I do I cannot get it to come on, I have tested and re-tested the electics and the fan, and all seems fine. So I am now having to go and buy a thermometer to test the thermostat in the pan and somehow the water temp in the rad.

at the moment I would not even bother with one just wire a fan to a relay and switch.

Do you think I have wired it wrongly, Si said it looks fine.

the only question in my head is will the thermostat allow a 12v current to pass through it once it is activated.

fan shouldnot becoming on this timeof year surely, especially on a derv, my v8 sits at 80 at the moment, so an electric fan will not cut in.

I've got a Kenlowe fitted to mine & if set up correctly, the fan never comes on when driving on tarmac (even in the summer). Even when sat in traffic it hardly ever kicks in as the temp never rises too high.
The only time the temp rises & the fan kicks in is when I'm travelling slowly uphill on a greenlane & the fan soon brings the temp down.

i got the standard thermostat from x-eng that they recommend, I have it on the lower setting though.  The fan only comes on while im green lanning, never seen it on whilst road driving.
