Many of you out there may already know this, but for those who don't here 
goes.
I recently did a single rad conversion, thanks to Chris Semple, and I am very 
pleased with the results. The final piece was a better fan. After a lot of 
searching at junkyards, Chris accidentally hooked me up again (I had to pull 
it myself). The 1987 1/2 NG motored coupe has the same UrQ, 4000 5cyl 
radiator, plus an auxiliary rad, but most importantly it has a 5-blade fan 
that bolts right in to the UrQ. Importantly it has the two speed hookup, 
normal and high for AC. Just in  case you care about replacing your 3-blade 
UrQs are three-speed (two via the motor [three-pin connection] -- high and
hurricane for the A/C; the third-low/engine off-via external relay-
bypassed dropping resistor) radiator fan setups
fan. HTH
*WARNING*
If you are talking about the "bigger" (more powerful) fan motor (from the 5000 
series? others?), the stock UrQ wiring will *NOT* handle the load. The relays 
and fuse box ***WILL NOT*** handle the load.
Just a heads up . . . from one who has replaced much melted wiring, relays, 
fuse panels, and the like.

I know they're three speed fans, but only two speeds are related to the motor 
itself. The 1987 1/2 coupe fan is exactly the same as the UrQ's except for two 
things. 1) 5 blades. 2) No hose connection. Seeing as very few cars have the 
hose connection, I think it's not a big deal. HTH
