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.
49320
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?

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!

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