Figured I'd throw up a post with a few pics and details since I couldn't find much when I was looking into this. Found the need to upgrade my cooling fan here recently. Between the hot weather and a big blower turning hard temps go up. When I run the killer chiller it of course dumps all that heat in front of the radiator which makes coolant temps go up. I was hitting 244F coolant temp not even beating on the car in some miserable 100F or so.
Did a little searching and reading and the Lincoln Mark 8 cooling fan was the most powerful single fan that Ford ever made. Specifically the 97/98 fans pushing some 4500 CFM. Beat only by the 2010+ F150 dual fans coming in at some 6500 CFM. I got the dimensions of the F150 fan setup and there was no way in hell that was even remotely going to fit so that was out.
Picked up a 98 fan and got to work.
You'll notice the Mark 8 fan has a shroud too. That alone will make a huge difference.
After several test fits the tabs were trimmed down to this
Here's a notch I made for the ABS motor. I also slotted the holes on the ABS module's bracket and slid it as far back as possible to reduce the notch size and interference.
It actually fit in there amazingly well. A stock supercharger reservoir would be OK too but I'd end up having to come back and notch it for my larger tank covered in neoprene.
Here you can see the bottom fitment. Again very nice.
Here's the notch I had to put in the top right corner for the intercooler reservoir.
Installed with notch.
The intercooler reservoir and neoprene covering seat in there like a glove and close off the opening and fit perfectly.
To make the wiring very simple and clean I took the pigtail harness from the Mark 8 fan and the pigtail off my stock fan and wired them together to make a clean and neat jumper harness. The stock fans have two circuits for low and high speed, the Mark 8 is a single speed fan only. So my jumper harness ties both the low and high speed circuits together feeding the Mark 8 and in my tune I'll set both low and high to come on at the same time.
All installed and you can't even tell. Like stock but wickedly more powerful and with a shroud. Excited to try this out soon.
