Budget electric fan replacment
After I got my ultra-guage I was seeing temps go over 212deg and my electric fan was not coming on. Upon further inspection I found the fan motor completely seized up and the fuse blown. The cheapest replacement fan I could find cost $375 before shipping so I decided to go the budget route. I used this fan, which after promo codes cost me $55 shipped: Buy ProForm High Performance 12" Electric Fan Universal 67012 at Advance Auto Parts
It is a universal fit meaning it is retained with little crappy spikes that push through the radiator fins. Also, I had to flip the blade over to make sure it pushed air toward the engine.
Here is the old fan with blade off next to new fan
Instead of using the crappy spikes I removed both motors from their plastic shrouds and swapped them over. None of the holes line up so I just drilled new ones. Picking the location with the widest amount of plastic. Dont want to drill through one of the tiny ribs.
New motor in old housing
And to make sure it doesn't jiggle loose a little bit of locktite was used.
Cut off the connector from the old fan and spliced it to the new, bolted everything back up.
This is a cheap way to replace the fan and be able to use the factory mounting points on the shroud.

Not sure, at the same time of installation I also changed the thermostat to a cooler one, which dropped my temps across the board by about 5deg. The highest I have gone since is 206deg in stop and go hill climbing. Before I was seeing up to 217 deg. in stop and go traffic.
This is the thermostat I used.

On a D2 the ECU monitors the coolant temp sensor and with the AC control decides when to turn on the fan relay in the underhood fuse box. So no adjusments, but a clever owner could add an adjustable stat or switch to bring fan on earlier. On a D1, fan runs when AC is turned on. Some people that pull trailers on long hills have added a switch in their car or truck to give that extra cooling boost.. rather than waiting for 212 to be reached.
Add a switched earth ground (a stat or a switch) at connector C570, pin 2 (green& white). This will energize the fan relay. Connector is on the inside of fuse box, easy to get at. See pix.
