Changing an alternator out on a truck.

Any do-it-yourselfers out there?
A friend of mine says it is pretty simple.

What kind and what year??

I've never done it myself but I watched a buddy do it and it seemed simple. Probably not bad if you YouTube it

It’s very simple.

Depends on the truck.
Toyota Tundra trucks used to have the starters under the intake, and possibly still do?

If it’s an older vehicle it is. Watch a few YouTube videos. Most likely someone on there will walk you through it.

YouTube it and there's probably an exact vehicle with it done.

Highly dependent on the vehicle. I’ve changed one with only a spare tire kit and a crescent wrench and others where I needed a lift to move so much crap out of the way.

Depends on the truck. I did mine less than a year ago. Toon longer than it should have because I don't have all of the right tools but I saved at least $400.

Your make and model will determine where it is and how much stuff you have to remove first to get to it. Once it's accessible, it's just a matter of removing bolts and a plug, putting the new one in, and doing everything over in reverse order.
Likely someone has a tutorial video on YouTube.

Two potential paths:
A. Two bolts, readily accessible from above
B. "Step 1: Remove ________"
There is no in between.
If it's B, run (don't walk) to a mechanic.

If you have to ask…..
Since the average age of the TD poster is mid 40’s, I can see why there are so many “it’s simple” and “just go for it” posts. For the last 100 years prior to 5 years ago that was true. All last model GMC’s use one use stretch belts. A few other manufacturers have some quirky changes also.
You cannot stretch the GMC belt by hand. You must have the tool or you can zip tie it to the balancer on the right side and crank the engine and it will self seat (about 4 zip ties)….the zip ties will break themselves off.
Anyway….very vehicle specific….could be a 10 minute job, could be a nightmare if you are not familiar around an engine and late model cars.

I’ve changed several alternators over the years: 2008 Tahoe, 2010 Honda Accord, and 2012 Suburban. All had enough room under the hood to remove bolts & belts and swap out the alternator. Watched YouTube videos and took lots of pics. To stretch the pulley belt, I rented a long socket tool from O’Reilly Auto Parts. Paid a $25 deposit, used the tool over a 1-2 hour period, and returned it while receiving my money back. My daughter drives a 2018 Infiniti and the engine compartment is very tight and has very little room to change parts.
Changing the alternator took me 2-3 hours , taking my time, and cost around $300 for a re-manufactured model. Turned in the old one and got some $$ back.

I assume F150 since that is the baw truck. My alternator also just went out and I pondered posting the same question. There's a couple of walk thru videos on YouTube relating to the F150. They make it seem simple, but people who know what they're doing often make it look easier than it is.
Edit: OP has a Ram, nevermind.

It's about as simple as anything gets. You should be able to look at it and figure it out. A couple of bracket bolts a n electrical plug and a belt.
If you can't do it, turn in your card.
Oh, disconnect the battery before you frick with it.

If it's a 5.4 Ford from turn of the century it should take about an hour if you drink a couple beers during the process. If no beers about 35.0 minutes.

It all depends on where it is

You can only do it if you buy $10k of stuff from Snap-On first.

15 minute job. It's 2 bolts and a plug.
Take belt off
Take electric plug out
Remove 2 bolts
Remove alternator
Reverse the order for the new one.

It just depends on the vehicle. Some manufacturers put it in an accessible location while others you may have to remove other parts to get to the alternator or to pass the alternator to get into position.
I changed the one on my Honda Odyssey. There were 2 bolts holding it up, but I had to move the power steering reservoir and radiator overflow to slide the old alternator out and the new alternator in. The other hassle was the serpentine belt and getting that thing routed properly.
