The voltage regulator in the Alt is temperature compensated. The colder the higher the voltage.
My alt pushes 14.9v on a cold start and settles into 14.5 after a mile or 2.
Edit: the CS alternators push 14.9v on a cold start in the fall spring and winter. The Denso on my 97 only pushes 14.5 in the dead of winter and settles to 14.2 this time of year as the alt warms up. I keep a USB adapter with a built in volt meter in my cig lighter.

Well that settles it!

If (when) this one fails, I'll definitely consider that option.

I have a CS130 from a Saturn that I'm thinking on looking at buying the cable adapter and the center body that has the proper mounting to go in the 4Runner. It's a 105a and external cooling fan.

4th gen alternator
2006 V8, installing dual battery and wondering if my alternator is “smart” or not, need to know so that I can either purchase a less expensive VSR (regular alternator) or do I have to cough up big bucks to get a Redarc and similar due to a “smart” alternator, thanks all

You're in the 3rd gen section
3rd gen section
Well it looks like the search engine has done it again, I did the search for dual batteries in the “4th gen” section, don’t know how I ended up in the “exclusive, I can’t ask general question” section, anyway thanks for the response it was very helpful in my attempt to do a build, cheers

First off, asking if you have a "smart" alternator for your 2006 is something that is year and generation specific hence why no one in this section (unless they also have a 4th gen or have owned a 4th gen) would know. We don't share an engine with any 4th gen. It would have been great if 3rd gen's came with a V8, but not a factory option for us. Not exactly a general question is it since it doesn't apply to the general audience here.
Secondly, try using this google specific search so that you don't end up in the wrong section again: site:https://www.toyota-4runner.org/4th-gen-t4rs/ - Google Search Make sure you leave a space between the end of that and whatever phrase you want to look for. Good luck with your project. Might go better if you took the stick out of your ass. Feel free to respond, but I really don't care what else you might have to say.

Oh boy. Mad because they are in the wrong sub forum... [ ok. Things happen. 
]
Trying to blame Google for posting in a different section.. [ :/ I get it to a point. However, it's well documented how to search effectively ]
Then trying to ruffle feathers making a silly dig. [ Maybe some folks just ar not happy people ]
[ I belive there is even a general question section of this forum as well..]
Best of luck to you and your product.

Maybe if you weren't so focused on being unnecessarily frazzled over literally nothing you could calm down and surpass the attention span and reading level of a 4 year old that's required to properly post your question. Just think, if you did so then your question could already be answered. But instead here you are, thumb up your ass, still on square one.... And while you're at it, be cordial to those that are cordial with you.
Just a suggestion :shrug:

When you see badluck getting frustrated, I know something wrong. As he fixes my information mess ups on posts. I personally, don't mind at all because I want accurate information out there. I even go back in and edit or delete to make the corrections when possible.
I can be wrong as this is how I learn to be better. Plus others learn from the mistakes as well.

I think it was well warranted. Quite an unnecessary bit of attitude thrown back over such an insignificant comment, like we're some sort of overall experts on 4Runners. Well I mean, some users her definitely are, but you get my point.
The irony is if it really was a general question and not something so specific then someone probably would've answered it fairly quickly. Or the fact it was meant to steer him in the right direction faster...

I’d like to know what Smart means…..

Cars for some time now have had alternators that will compensate for a tiny drain in the battery (which naturally occurs with time) by increasing its power output. This is the why you hear about taking your car in for a battery replacement - some cars must have their ECU cleared (I think?) when a new battery is thrown in otherwise the alternator will overcharge and cook it right off the bat.
At least that's what I'm assuming just based off my knowledge about cars.

To me that sounds like the typical job of a voltage regulator. Some manufactures have them in the ECU (Chrysler) and some have the Alts internally regulated.

Yup.. It is what it is.. I dont blame him.
I do know are alts are not smart and we have 2 different amp levels on the v6 gen 3. The later years are higher amperage alts and yes you can run a higher amp late model on the early years if you really want too.;-)

I have both the 70a and the newer 80a Alts and neither one of them push more than 40-43a at idle in gear with the foot on the brake at 600rpm.
Once again what is smart? The VR (voltage regulator) maintains a certain voltage based on load and heat sink temp. The higher the voltage the higher the charge. Our rigs need around 15a to satisfy the electrical load of the PCM/ECU. Anything above that goes into the battery…..
What is smart about that. It’s been around since the first solid state voltage regulator was introduced in the early 70’s.
