What's this switch?

[Jim the Sunderer]

Hello gentlemen,

I have just bought a '97 Discovery 300TDI.

I see where the heated seat switches should be, a pair of swiches that say 'KENLOWE' and one of these under the bonnet.




Anybody got any info on this contraption?

Thanks.

Thermostatic swith for the KENLOWE cooling fan.

It replaces your viscious fan with an electric one.

Nasty shonky rubbish which'll cook the head. Rip it all out and put the vicious fan back in.

I ran around for 2 years with no fan at all [no towing]...those 200 tdi only get a little warm stuck in traffic on a hot summers day.

Or if the radiator is caked in mud and not cooling the water.

They tend to be big systems so cool quite easily but a couple of things will cook them.

• Knackered Radiator
• mud baked on to radiator
• Towing a heavy load up a lot of hills hard

The extra fans suggest a poor solution to another problem or lots of towing.
If it was a petrol you could add wading in deep water where the fan sprays water all over your ignition system. Then it is useful to have a means to turn them off when wading.

I like electric fans on a Landy rather than viscous/fixed, mainly for the reasons mentioned above, but also because on my Series III it actually gets vaguely warm in the winter and every extra bit of hp helps on a 2.25.
In my experience the Kenlowe controllers last 4 years max if you do any off roading, and you have to make sure that the hose is decently sealed around the copper tube.
Keeping the electric fan but replacing the switch with something like the x-eng solution or revotec would be a good idea. http://www.x-eng.co.uk/X-Fan.asp and

To answer your question rather than discuss the merits of electric fans, the top photo (switch) is to override the thermostatic switch to manually turn the electric cooling fan on. The other photo is the bit under the bonnet. There is a temperature probe which sits in the cooling system (normally near the top of the radiator) and the box is a thermostat to control the temperature at which the fan cuts in (to suit individual cars).
