Over the last couple days I changed my fan clutch according to Timmy's video. Being in the rust belt, the 4 nuts didn't come off so easy. For the 4th bolt I was lazy and tried to loosen it while it was down in the 6 o'clock position, I didn't feel like bumping the motor to turn it so it was at 12. Well of course I stripped the nut head. It would be nice to find a set of wrenches that actually fit snug over the nut. These are "12 mm".
So then I had to bump the motor to get the bolt up top. Then I had to spend half an hour hand filing the edges of the nut down to 7/16". Of course that one fit nice and snug because I checked it frequently and stopped filing when the wrench just barely squeezed on. Then it came off nice 'n easy.
So that nut is toast and the other 3 aren't so hot either, being partially rounded off by the so-called "12 mm" wrench. So I called up Toyota today and they said I could stop by and check their bucket-o-nuts but I won't have time. I found some other nuts in my own bucket-o-nuts that fit, that came from somewhere else on my 4runner LOL and I'll use those until I can get some nice new ones.
New and old fan clutch:
There was a lot of dust and grunge in there so I cleaned it out
Also all the metal on there had rust but I wasn't going to fix that so I just hit it with rust inhibitor. It will be coming off again for the timing belt job sometime in the near future. The four 10 mm nuts holding the fan to the clutch were rusty too but they are in decent shape since they came off easier and the tight fitting socket didn't round them.
While I had the space available I decided to finally do something about that ugly rust on the frame that always stares me in the face while looking in the engine bay:
After an hour of screwing around with the dremel I had 10" of frame cleaned off, on 2 sides:
Primer:
Final coat with Rustoleum black wheel paint which I really like for underside repair:
It always takes me 4 x longer to do anything than it should because 1) the bolts are always rusted, and 2) I take the opportunity while stuff is off to repair rust.
At this rate I'll have the truck rust-free when I'm 94. Next up: replace clutch hydraulic cylinders (and repair rust while I'm in there).
Edit: thumbs up for anyone who can tell me how many times I said rust in this post.
