The electric fan install is complete and so far seems like a success.
The fan is controlled by a variable speed controller, which means that once the temperature reaches a certain point (that I set) the fan kicks on at about 60% power. Power increases as necessary up to 100% power when the engine is 10 degrees over initial set point. Wires were run in sleeving to give it a nicer look, along with heat shrink at all junctions. The fan and temp probe have quick disconnects on them in case I have to pull the radiator in the future. I mounted the controller on the firewall because there is no more room under the dash. It's much easier to access in order to adjust on/off temperature.
The fan is quiet....orders of magnitude quieter than the old one I pulled off. At low speed it is quieter than the running of the engine. It also pulls far less amps than the one I replaced. It hardly puts a burden on the alternator, whereas the old one created a noticeable drop in voltage.
Video:
The inline fuel filter seems to be doing okay, no leaks, doesn't appear to get too hot. After a few tests up and down the driveway I took the car out on the road. I drove it a couple miles, not too far from home just in case I got stranded again. One of my daughters was brave enough to come along....I told her we may not survive. No fuel delivery problems that I could tell, fan kept the engine temp steady. On my temp gun at the upper radiator tank it reads about 175 when the fan kicks on. The reading on the dash is about 185.
I'm not used to driving the prewar cars....they are definitely slower than my Panama. Shifting is going to take some practice. Brakes need more work. It's better, but nowhere near as good as my Panama.
