This weekend started the carb cooling fan restoration… It was in fairly decent condition, but there was enough rust on it that I decided to wire-wheel all the steel parts.
As of writing this, I have most of the hardware sitting in Evap-o-Rust, and the fan cowling / motor housing pieces are primed and painted. I’ll reassemble it after a day or so curing.
I did end up replacing the three M3 screws (and their washers) that hold the circular plate in with stainless steel equivalents. I got two of em out ok but butchered the third due to a struggle against rust. Im not sure if these fan assemblies naturally trap moisture or if my donor fan came from a wet climate… I assume the latter as Mr. Toyota thought to add drain holes. We’ll see
The Nippon Denso sticker was in good condition so I took my time and stopped short w/ the wire wheel, using hand-sanding / emery boards to get up close. Masked it off for painting and I’ll see if that all worked out in the AM.
I lucked out and all the rubber parts were in good condition, still pliable. I am going to try and preserve/protect them using some Shin-Etsu silicon grease, which I hard heard good things about when I was researching rubber restoration during the heater blower restoration.
Done so far:
Still to do:
Forgot to take pics of the wire-wheeled parts… D’oh!
Anyways, here’s the “before” pics:

Done so far:
- Disassembled, sorted and washed parts
- Rusty hardware still in decent condition soaking in evapo-rust
- Coated rubber parts in silicon grease for a day (will wipe off excess tomorrow)
- Removed all paint from fan cowling and motor housing parts
- Masked, primed and painted
- Purchased SS screws to replace rusted-out ones
Still to do:
- Clean inside of motor housing, oil bearings
- Clean motor leads / high-temp wrap / connector
- Clean up manifold temp sensor / bracket & install
- Put together a connector / lead / hoop terminal for the manifold temp sensor
- Reassemble the carb cooling fan assembly
- Install and hope it works

And here’s the progress pics today (haven't snapped any with paint, just primed). Tune in tomorrow for the thrilling conclusion!

Carb fan restored! I re-assembled the fan shroud, motor (tested it as well), and applied new insulation (weather sealing from Ace). I also wired up the manifold temperature sender to a connector I had saved. I installed everything on the truck, pretty happy with how it all turned out! Except for one thing... The fan isn't coming on after the truck has been run awhile and is nice and hot. I'm not sure if its the controller, the temp sender, or something else, but I have a used fan controller on its way, so we'll see if that works (and if not, I'll dig em open and do some testing).
Here are the (nearly) finished pics:

Whelp, found the problem, ha! I wasn't expecting so much gore on the inside of that fan controller. Looks like the cap done 'sploded and sprayed its guts around inside... I see some charring on the board as well. Lucky for me I have another controller en-route... Hope it's doin better than this one. If not, looks like I get to do some home electronics repair.
Looks like the truck is being consistent in terms of electronic gremlins, so in other words the sky is still blue

Update on the carb fan controller... I threw in the towel after screwing around with two non-working boards. Bought replacement caps, soldered 'em in, floated any loose connections... Nothin. I thought about mapping out the circuit, learning some basics of electrical engineering, but my list of projects isn't getting shorter, so I punted. @Engineer8000 to the rescue, he had one for sale, priced fair and he shipped it fast. And boom, I'm up and running! It's working as intended, and I have way easier starts on a hot day after the truck has been parked.
One day I may try to get one of my two boards working so I can have a backup, in the mean time, we'll put those on the shelf and move on to some other things:

- Just got a rebuilt dizzy and working igniter from @4Cruisers, thanks man! I'm sourcing a coil and band to get it all working, and I need to unwrap the loom in the engine bay to see if I still have the resistor wire in-place (something I just learned about on '78s). If I do, sweet. If I don't, well I'll be looking for an appropriate ballast resistor. This is the project I'm most excited about as I currently have no working vacuum advance and I want to see how the truck runs, but I need to take it slow and make sure the wiring is all correct.
- I finally got my order of locks/keys from ToyotaMatt, and need to get 'em installed. Looking forward to having working door locks so I don't have to crawl through the back every time I need to unlock the truck
- I'm ready to install headrests... Got some from ebay but they were grey, not black. Took several weeks to slowly dye the vinyl to something approximating black, and I've hit the "good enough" point. Now comes the fun of heating up the seat backs on a hot day to unwrap / re-wrap em. I have 3D-printed guides from Proffits, we'll see how they hold up.
Thanks for sharing your new Cruiser with us.
You paid enough to take the car home and you are pleased with the Cruiser. Sounds like a great deal to me.
I have a 78 also that is slightly modified and I too enjoy playing and driving her around.
Stock heater, especially if you have the rear heater, works ok to get the job done. I have thought about going Vintage air so I can add Air Conditioning. My wife says we don't need it and I'm getting too soft in my old age!

So far this summer I haven't been putting it through its paces, but it works! We did use a bit camping on some colder days, and to be honest its really there to ensure I can defrost when needed. I might change my tune when I get around to redoing the exhaust... @Mark Jennings recently replaced his with a stainless steel one and insulated it and it sounds like that has improved both sound and heat transfer. I plan to do the same eventually, and when that happens I may find the backseat is too cold for the kiddos. I may decide to do the rear heater at that time, or just tell them to wear a coat
As for A/C... I'm slowly getting used to just baking in the truck as its my daily driver now. I think with some insulation applied in the truck it would be a lot better, but its cheaper to add beaded seat covers than A/C at the moment (and frankly, she don't have that much power to give)
Looks very nice and clean.
I don't seem to have as much heat transfer from my exhaust, or i am just tolerant of it. I plan on adding insulation, Dynamite, to the floors. I plan on only covering where it will be hidden by floor mats.So far this summer I haven't been putting it through its paces, but it works!
