I don't know if anyone else has done this but i just bought a BWD coolant temperature fan switch at local auto parts store for 20 bucks. i don't plan on having my temperature gauge ever work again so I took the thermostat housing out for a cleaning and to make sure the thermostat still worked. i pulled the sender off the back of the housing and the swith i got (part # TFS500) fits perfectly. i'm going to wire the switch to key on hot and hook the other side to the fan then chassis ground the fan. i didn't see the cooling fan "how to" anymore so I don't know if this was already astablished. just wanted to pass it along.

I looked into fitting a temp sender style fan switch when I made my conversions but opted for the Electronic temp sensors so as to keep the Temp gauge and they are really cheap.

no harm in what you are doing so long as it operates the fan as you wish

my gauge doesnt work and i didn't feel like popping down for a new gauge. I'm looking for a radiator cap that has a thermometer on it.

Let me know if you find one, that would be cool as hell.

At what temperature would the fan turn on with the BWD TFS500 switch?

I went with a manual over-ride switch on my 650I, so now I just flip the switch as soon as I enter the city. The gauge never climbs over the point that it runs at on the highway. Very happy with it now.

I have a manual over-ride switch on my GL650i but I have never used it yet, except to try it out. But then we haven't had any hot weather this summer. It was installed by the PO and probably cost all of two bucks.

That cap looks cool. It may be too thick for a CX though. There isn't much room between the tank and the radiator. Not to mention you wouldn't be able to read the temp on it.

But I do like the idea.

The cap would be a waste as you wouldn't be able to see it anyway. It would be easier to just fit a mini gauge to the thermostat pipes.

There's probably something smaller and cheaper made in china that would do the job just as good.

For my Ducati fan conversion, I found a simple, adjustable fan switch at Advance Auto Parts for around $20 (Imperial part #226203). I mounted the switch on top of the air box, zip-tied the sensor bulb to the top coolant pipe, and set it to turn on at 200 deg., and off at about 185.

I have trust issues with temperature switches. Or maybe I'm just paranoid.



I used a simple switch with a red led to turn the fan on, see pic below. I have to say I hardly ever use it but we dont get extreme temperatures over here.

I like it GreenCXman




Reminds me of the booby trap arm switch in madmax 2 - "The car's booby-trapped. Touch those tanks and BOOM! You'll blow yourself apart." or in your case, it'll switch the fan on




I swapped out my loose, rattly fan recently as I was worried that it might explode like you said.

A buddy of mine just yesterday gave me, from what I can tell is a CX650 radiator with electric fan, temp sensor and hoses. The 3 mounting points appear to be identical to my CX500. The radiator looks nearly as good as mine on the inside and mine was rebuilt about 18 months ago. The exterior is fine too but, my question if someone knows, will a CX650 thermostat housing top, bolt on to a CX500 thermostat housing? This radiator top hose is in the center of the tank and my 500 is to the left if sitting on the bike. This and moving the fan forward are the only 2 mods I see to be done to make it work.

Thanks

Thanks for the info on this part, EasleyRdr. Looks like it will do the job for me when I switch over to an electric fan (probably during the winter). The current plastic fan I am using has a small crack, but it is holding up well (I'm not using the older fan with multiple cracks around the sleeve!)

Hey Shep,

I clicked on the link to your post yesterday and book marked it. When I went back today all I got is a blank page. I can open the engine page but, every topic I click on is a blank. Any clues to open them?

Thanks
