Alternator overdrive pulley install in Toyota Sienna.
I want to speed the alternator when the car is in idle, so that it will produce more amps of electricity. The OEM alternator pulley diameter is 58mm, I installed a smaller pulley of 49mm diameter.

Toyota Factory Pulley:

49317


Factory pulley Vs smaller pulley:
49318
49319

I grinded some meat off the new pulley so that it could sit on the inner racer of the alternator bearing.

49334

49321


The new pulley needed a new M14x1.5 nut, the new nut will be able to grab 3-1/2 circles of the threads of the shaft, while the OEM nut with flange only grabs 2-1/2 circle of threads.
I bought this nut from Homedepot, and from amazon, free shipping.

Any guess as to what the equivalent engine RPM will be at idle compared to the original?

Any problems adjusting out the belt? Looks like you shouldn't.

Add wires: Alternator to starting battery, Engine block to car frame, car frame to starting battery negative.
I had some left-over cables and I used them for current flow.

Looks like the old one still had some life left. But nothing like a reassuring feeling with the new set!

I haven't installed the alternator with the smaller pulley yet. I changed too many things of the charging system, and I wanted to be sure that those changes worked first, then install the smaller pulley.

It was very nice to be able to use the instant pot to cook while on the road. Also, an electric kettle is very convenient.

Worthington State Forest, State of New Jersey.
On the way to the New Jersey Worthington State Forest, the sienna CC stopped working. It showed an E3 code. I stopped and restarted the engine, this maneuver did not solve the problem. I then used a wet cloth towel to clean the laser sensor housing surface。 The the CC returned to work (the surface did not look dirty at all).
We hiked the Mt. Tammany. The trailhead parking was always crowded and full. So, arriving the night before would be a good idea.
The view of the Delaware Water gap from the Mt Tammany trail was stunning. It would be even richer in the fall with foliage color.

Driver side cv joint boot leaks
While at the campground, I checked the undercarriage of the Sienna and found the driver side cv axle inner boot leaked grease. The boot was replaced with a new NAPA boot 2 years and 20K miles ago. So, the NAPA CV boot is a no-go.

FWIW, that may not be the boot's fault. If the joint itself is failed/failing, I would expect it to degrade the boot faster. Still, 2-years/20k miles for a sub-$20 fix isn't all that bad a deal. Personally, I'd probably replace it with a new Toyota/OEM joint though.

Regarding this particular Sienna:
The tranny rebuild was done when the car was under previous ownership, at 150K miles, and in year 2016. Timing belt and water pump replacement (the 2nd replacement), and steering rack and pinion replacement was done in the same year.
I bought the Sienna two years later in 2018, 178K miles.
When I checked the car after the purchase, the transmission lacked 2.5 quarts of the ATF. It is either caused by the tranny rebuilder who didn't know how to check the ATF fluid level on a toyota, or the small leaks of the tranny for 2 years, or both. The ATF was in pink color.
I added the 2.5 quarts of Type IV, tightened the ATF oil pan gasket bolts, and did a drain and refill, it was good. I did not open the oil pan and did not replace the strainer.
2006 Sienna Limited FWD, with Laser Cruise Control (working), no GPS (I preferred no GPS), with sunroof (I don't like sunroof.). I looked at my spreadsheet, and I already spent $2,281.56 on parts to restore the car (Lower control arms, wheel hub, rear suspension, tires, etc).
The Sienna was in southern states the whole life, so no rust at all.

No electricity, no water, no cell signals.
Very nice trails.

Getting water from the brook over the bridge.
