I'm doing the conversion also. My question is this...do ALL probes have the same thread? I ask this because I've got the Saab set-up. With this one I want to tap into the upper radiator hose EXACTLY like Saab does it. From Saab, a new tap is 90.00. From Flex A Lite, its 51.00. Will the Saab sensor fit the Flex A Lite tap? Or, is it a different thread? Just trying to collect all I have to before I get into it and find out I need something else. Thanks guys...

Check my build thread. I'm on mobile so I can't figure out how to link properly but I set mine up slightly different from everyone else. I just got a parts store adjustable controller with a probe for like $40.00 and wired it into the "high" setting and ran a switch to the cab for constant low if I need to over ride it. Works perfectly for me.

I used the Hayden controller with a probe and it works like a champ. As far as air cooling the probe I used the auxiliary cooler mounting strap thingies to keep it securely in the fins and also shield it from any wind.

The great uniting factor is that we are all jeepers at heart and are willing to help each other out even if its just a little. That's what the jeep wave is all about: community.

After finding all 1 Volvos in this area has been robbed already, I've been piecing together the parts for this fan. The only thing I am lacking is a high current relay to hook up to the high side of the Taurus fan. I know it shouldn't have to be used according to all I've read, but I would like the option to manually turn it on if needed. There aren't many choices out there except in solenoid style. Is that what is recommended? I've looked at this, but am not sure if it is continuous duty or not: http://www.amazon.com/automotive/dp/B001PNMBE4

This bosch is just the ticket.


I was able to find them online for about $18 each at solarseller.com

Thanks. I had been looking at that. It apparently is now a Tyco V23232D0001X001. Or BR-5000 on Amazon. On order now.

Just an FYI for anyone who wants part numbers. Here's what I ended up piecing together in parts and a schematic of how I wired it. Not finished yet as I broke a hose clamp putting my radiator hose back on and won't make a trip to town just for that.

Projectbox from Radio Shack 7x4 7/8x3
2on-off-on 275-0711 Toggle switches from Radio Shack

All finished. A couple of runs made with no issues over the last week. Temp runs very close to what it did with the clutch fan. It cycles on and off cleanly. Low and High bypasses work. Ran it today around the interstate at 65 to 70 with temps in the low 100s. Gauge showed about a needle's width above the 210 mark, so that looked normal. Those who use their butt dynos must be more sensitive than me. Or else mine is broken. I didn't see any noticeable difference, but the jeep only gets driven on Saturday for the most part. Guess I'll wait and see if there is any change in mpg or not. Either way, this is just my play toy. I like doing things like this to it.
