1989 Ford Bronco - The electric fan controller, Advance Auto Parts Imperial/Hayden part # 226204 1989 Ford Bronco - I walked down all the rows of Ford cars looking for a Mark VIII to get the fan from, as I've heard its the absolute best one out there. I w… 1989 Ford Bronco - 1998 Thunderbird. This pic shows the depth of the electric fan into the engine bay, and kind of what to look for when walking by one. This… 1989 Ford Bronco - Theres a 1994 t-bird next to it with 30k miles more than the 1998. I took the newer one with less miles, but there is another one up for gr… 1989 Ford Bronco - All the stuff I have amassed so far for the swap, and the Taurus fan. 16 inches. Hard to see but I promise. Its 16 inches. 1989 Ford Bronco - Taurus fan: 22 inches across 1989 Ford Bronco - Taurus fan: 17 inches vertical 1989 Ford Bronco - Taurus fan: About 5 inches deep 1989 Ford Bronco - T-bird fan. Also 22 inches across, and since its square, its about 22 inches vertical 1989 Ford Bronco - T-bird fan: About 5 inches deep. 1989 Ford Bronco - All my stuff. A new quality pair of wire cutters/strippers/crimpers from Grainger, project box, grommets, solder, fuses, random diodes, 300… 1989 Ford Bronco - T-bird fan 18 inches across 1989 Ford Bronco - Remove the 4 fan bolts... 1989 Ford Bronco - It might take some persuasion depending on how long its been on, but mine came off easy, only been on there a year. 1989 Ford Bronco - Thread the fan bolts back in. These also hold the outer water pump pulley on. 1989 Ford Bronco - T-bird fan held in place. There is very little room, 1-2 mm between the motor and the pulleys...not gonna work. 1989 Ford Bronco - Top down view, you can see its too deep to fit. This is most likely due to the extremely large radiator I have compared to stock. 1989 Ford Bronco - Taurus fan fits perfectly. Not sure why there is a difference, When I measured the thickness of the fan/shroud/motor they both seemed to be… 1989 Ford Bronco - I held it to the drivers side of the radiator, I'm not sure it really matters where on the radiator the fan actually is located. Anyway its… 1989 Ford Bronco - Held in the middle of the radiator, it's close but no interference. I guess I dont know how to use a tape measure. 1989 Ford Bronco - Not content to use the smaller Taurus fan, I decided to cut a little bit of the shroud off the T-bird fan. It had about 1 inch between the… 1989 Ford Bronco - Flush with the drivers side of the radiator, there is now enough clearance to mount it, and allow for some normal engine movement. 1989 Ford Bronco - Cut the mounting tab off the side of it. The tab was pushing the fan off the radiator a bit allowing for a gap, and thus the fan was closer… 1989 Ford Bronco - This is a blue/white wire to either the EEC or Fuel Pump relay. It is the most convenient tie-in I could find for the fan controller. 1989 Ford Bronco - This is the yellow wire from the fan controller that ties into the IGN ON blue/white wire by the FP/EEC relay. The glare on the meter is ha… 1989 Ford Bronco - This is where the project box is going. I'm leaving it open until I tweak everything and confirm eerything works correctly. 1989 Ford Bronco - I didnt have any heat shrink this big so I had to resort to electrical tape. This is the splice into the fan connector pigtail. 1989 Ford Bronco - The 300 amp continuous duty solenoid. Way overkill, and hindsight and some more research shows I could probably use the 40 amp fuse that th… 1989 Ford Bronco - Temperature probe installed right next to the inlet coolant hose. Its a nice tight fit, I cant imagine it will wiggle loose over time, but… 1989 Ford Bronco - This is the tie-in for the green AC ON wire to the fan controller. This tells the fan to come on every time the AC compressor kicks in. 1989 Ford Bronco - This is where I routed the wires for the fan. Gonna put split hose on it when I get around to it. 1989 Ford Bronco - Bottom up view of the routing of my fan wires. 1989 Ford Bronco - Dual Taurus fans mounted. This took some shroud cutting, and the are about as close to each other as possible. 34.5 inches end to end. 1989 Ford Bronco - Using cardboard to make a template to cut the shroud of the dual fans around the radiator hoses etc. 1989 Ford Bronco - layed over the fans I can see where I have to cut. 1989 Ford Bronco - It took alot of test fitting and trimming and more test fitting. About an hour of this and I had a good fit. 1989 Ford Bronco - My wiring job. Not sure I like it, not waterproof enough but its good for now until I do a massive rewiring job and add in my Thunderbird f… 1989 Ford Bronco - A simple 1 inch wide piece of aluminum I bent to follow the countours of the fan shrouds. This is stuck into the bottom of the core support… 1989 Ford Bronco - Close-up of a hand holding an electrical connector with wires.
