I think I'll hook it up so that the low speed comes on with the 180 elec temp sensor in my radiator hose, and the high speed is dash switchable. So down the road it will either be off because the engine is running cool enough or on low speed, but hi speed is reserved for low speed driving and idling.

I agree.. I think I'm probably going to do the same thing, go with the Hollister unit and the same wiring rational. But ... after doing some more research, there's a 740 Volvo 2 speed fan relay set that works well with the Taurus fan too. It has the right ampacity and has been/is available for minimal bucks on Epay too. I'm going to look into that also before making the leap. I might just pick up a couple of the Tyco HD 75 amp relays since I've an operable temperature control system in place... decisions, decisions..
It's odd though, I measured the actual fan blade wheel diameter on the new Taurus fan. It measured 16". I was wondering why they call it a 17" fan? I then measured the fan blade wheel on my current shrouded 16" Flex-a-lite fan and it measures 15".. Go figure?? The size rating must represent the fans' blade housings, not the actual blade diameter. (I guess sorts like bragging about an 8 incher when it's only 7"
)
The shroud size and the fan/housing stand-off from the radiator is smaller that previously specified in the thread (a good thing).. shroud measurements are 21" x 16". The width is trimmable to 20". The fore and aft distance (thickness) is 3 1/2", not 5". That pretty much duplicates my existing flex-a-lite setup, very adaptable. I'm pretty sure I can make this puppy fit.
I really don't have an overheating problem now but I still could use more cooling though, for my Pond 482. At this point I'm not planning on tearing it all apart this far into the season. My hopes are waiting for the annual "winter overhaul" for making the conversion. I will get everything together though, just in case I nedd to "fast track" the change-over.
