How hard is it to put an alternator on? I'm not mechanically inclined, but I like to tinker. Is this a job for a novice or should I have it done?

Thanks

on a older car its very easy. I mostly work on older chevy trucks and its a breeze a very easy project but then again chevy makes it easy on you there cars are very user friendly.

on a 350 V8 its like 3 bolts.

Usually pretty easy, what kind of vehicle?

On any car I've laid wrenches on it's been like 3 bolts... nothing to fear at all. What kind of car?

I did one on a 99chevy the other day that was the easiest ever, course I knew to use a backup wrench
(you might include the vehicle type, maybe a description, sometimes they are under the compressor)

Easy to do. A LOT more dependent on where the alternator is located on the engine. Access will be harder if it's down low on the block as opposed to up high. DOSCONNECT the battery before starting or get ready for some unexpected arc welding under the hood. Removing the negative cable is what i'd recommend.

Swapping the alternator is about the easiest maintenance you can do short of changing oil and filter.

Go for it, if you get in a bind, post a "HELP!" here and we will be there for you.

Apparently you've never seen an early-90's GM LQ1(3.4L DOHC found in 1991-1994 Lumina Z34 and Grand Prix SE/GTP and '95-'97 Monte Carlo Z34 cars) motor and it's alternator placement.

If it's the 4.3l in the van, it should just be 2 bolts and a little wiggling.

you would just have to look at and try to see what is involved
the chevy CAR I worked on had the alternator on the top front
I never specialized, so I don't have any make\models memorized

be sure to disconnect the battery(neg cable)

and the power wire on the back of the alternator
has a place to hold the bolt from rotating while you tighten it
because it will break a part inside the alternator if you don't
(forgot the name of the part) (rectifier bridge?)

the new belt tensioners are great, if there is not a diagram somewhere telling you
how the belt goes you may want to take a good look at the routing before you take it off
we have a really cool tool to take the belts off, without the tool, in a van, it might be tough

Disconnect the battery by taking the positive wire loose. You might need a pic of the serpentine belt config. Those things are a real mind bender sometimes. Then just take the thing off. Make sure you have everything hooked up right before reconnecting the battery.
