Re: Cooling fan temp switch

A few of us need to e-mail Husaberg/KTM and suggest controlling the fan on/off by using the coolant temp sensor input and have the computer control the fan ground.
You could use the ECU programer to program at what temperture the fan comes on and goes off
Would be easy for the factory to do!
Have a great ride

Re: Cooling fan temp switch

why would they do that?
They wouldn't be able to make a killing from selling separate fan kits

Re: Cooling fan temp switch

Just an update, I recently purchased and changed out the standard Husa thermo switch with ktm part #78035045000, a 95/100 deg thermo fan switch, rode the bike (2008 FE 550) in sweltering heat over the next 3 days while arrowing and then de-arrowing the course for a local event. Before hand the fan would run almost continuously causing the battery to run down, with the higher temp switch the fan did come on but not near as often as before (the bike never over heated). The battery remained fully charged for the whole three days making button starts the norm. Should have done this a long time ago. The switch can be found as part of the fan kit for 2008 and up exc's.
Price via Munn's and KTMTALK.com is $58.00!!

Re: Cooling fan temp switch

Good info, thanks for the part #. The link did not work for me BTW.

I recently installed the fan kit on my 550. So far i haven't had any battery draining(yet), runs alot too. Only runs for a minute or so after a hot shut down. I'll likely get that switch anywho. Mind telling us the price?

I had battery issues with my 2008 FE450 when riding slow technical trails in the south of Spain when the fan would run almost continuously. I never had the same problems in the UK as it's winter here all year long!

I have just swapped the bike for a 2011-spec FE570 and have a fan kit to fit to that this weekend. I note that the thermo-switch for the 2011 fan kit is marked 100-95 and is listed as part number 78035045000. Now there's a thing!

Don't waste your money on the OEM sensor, as the same unit for an '84 BMW 318i auto (and others) is available for $20 or less.
