the bearings in my viscous fan got a bit loose so I removed it. I have been driving without a fan for about a month now. Mind you it is cold out and I will need to get something for the summer. I am going electric.

I recently replaced the fan clutch on my 300D, the plastic fan had a crack so I replaced both. Hardest part was getting through the tight space to fasten the 4 10mm bolts of the fan.
The reason I replaced the clutch was the car was overcooling. At speed it would show less than 80 degrees C even if I know it was already warmed up. A coupled viscous fan at speed is also not good since there is sufficient airflow going through the radiator.

I just installed a 16" fan on my '85. I used an AFCO 200 degree switch, which has a 1/4" NPT thread.
AFCO 85286 Electric Fan Switch, 200 Degree On, 1/4 NPT - Speedway Motors, America's Oldest Speed Shop It went in super easy in the thermostat housing by drilling a 7/16" hole in the empty boss and tapping it. Overall I am quite happy with it. |

FYI, a standard motors switch # TS-121 (used on older 4cyl fords) switches on at 210°F(99°C) and off at 195°F(91°C), 3/8NPT with a fat sensor end (around 1/2" dia) and a push-on(not threaded, just ribbed) 1/8" output. It's around $15 online, $26 at my local brick & mortar. It works great on my gas truck.

I used this diagram to wire it up. I took the switched power off the disconnected EGR stuff on the left side of the engine compartment.

I edited my post to list the thread, it's 3/8NPT. This page has some nice closeups and sells it: 1986 Ford Mustang Engine Coolant Fan Temperature Switch TS121

I coated the drill bit with grease and went slowly and didn't have a problem.
It's still working great. |

Good it's working great. What does your's (and everyone else's) system look like? Are you using the AC aux fan as the only fan or have you added a second fan? What climate are you in? Do you have working AC? How is it performing?

What is the purpose of re-engineering the best engineered car ever made? Why not simply fix the original problem?

The viscous clutch fan has high parasitic drag, not an efficient design.

x2 Cannot agree with you more. Want a rounder circle, I suppose.
