I was in the junk yard today grabbing a volvo fan controller when I noticed its fan. It looks kinda interesting so I gambled and grabbed it for 20 dollars. I tested it on a battery and holy crap this thing puts out some air! After some research I found that some came with the same motor as the Taurus fan ( this is a different model motor but it is just as powerful as the Taurus that I have). It is a two speed motor and the blade is about 15". There is not shroud that you have to cut and it is much shorter than the Taurus shroud. I had a spare aluminum shroud laying around and after shimming it a bit. It came out to 3 1/4" inches and there is about 3 3/4" to the water pump. I am going to wire it up the same as the Taurus and test it out in a few weeks but from some rough measure measurements it looks like it might work!
I think you will have to place the center of the fan offset from the center of the water pump, unless you have short water pump housing. I don't know about the serpentine setup, but, had to do it w/ my V-belt setup and 3 row Champion fan.
That's possible, from my rough estimates it looks like it will just clear the water pump but I won't know until I take everything apart and try it. With it in place it looks to be about 3 1/4" in depth. It the water pump snout looks to be about 3 3/4". That is an estimate because my fan is in place and I am unable to get an accurate measurement until the spacer is off. But it it needs to be off set that won't be too difficult. Making a new aluminum shroud is pretty easy.
just a note to anyone looking for the Volvo relay...don't forget to get the wiring...they have their own plugs.
I finally found some time to get working on this. I had took a aluminum shroud that I had bent up awhile back and enlarged the center hole a bit more and mounted the fan. It fit perfectly on the shroud! I then noticed the fan blade stuck out a bit too much and went past the shroud so I cut some aluminum stock and added to to the sides of the shroud to push it out a bit more. I then drilled all the holes and mounted it to the radiator! It fits!! There is about a bit less than a 1/4" clearance between the fan and the pulley but it clears! I have yet to wire it up. I will probably get around to that tomorrow or Thursday.
Wired it all up today! Works fantastic! It took 1 minute and 10 seconds to go from 190 to 160! On low speed!
If have a chance this weekend I might write up a tech article on this setup if anyone else wants to try it.
I had never heard of it before and neither had anyone else who I talked to about it. Good fan though.
Update on this, the original fan I found had an external speed controller. The controller burned up and I only had high speed, and I messed up the shaft trying to remove the fan blade. Unfortunately it seems that model fan was a one year only model and costs $200+ new. So back to the junk yard. I found another Volvo that had a similar fan and this one had the same motor as the Taurus fan. Unfortunately it was too large to fit centered on the radiator (3 core champion) and I had to build a custom offset shroud. I learned from the other than that the shroud that you can get off eBay is too thin and can cause a vibration with high speed that can be felt in the car at idle. So when I made the new shroud I doubled the thickness of aluminum stock. To get the fan to fit the fan needs to sit off the radiator by about 3/4" to 1" on the passengers side. By doing this it will clear and still pulls a ton of air. I added a piece of aluminum on the side so it only draws air through the radiator and to add another mounting point. It cools my engine no problem at all. It pulls a lot of air at the inlet and still some on the other side of the radiator. It covers about 3/4 of the radiator. To use this option you will need some aluminum welding skills, but it is definitely worth it. This was only the mock up shroud but it is working fantastic
