In this video, I replace the alternator in a 2003 Mercedes E320.

TRANSCRIPT:

So in this video

We're going to be replacing an alternator

in a 2003 Mercedes E320

He's on his way now

Step One, Disconnect the battery.

Do the negative...negative side

There it is... Make sure it cant touch it

You don't want it coming back on and

giving us a shock.

Alright looks good.

Okay we're going to take off these covers.

So next we gotta remove the belt.

Here's the tensioner

17mm, on the tensioner.

aaaand...

Just turn it

And the slide... Actually I am just going to slide the

belt off the alternator.

There we go.

And then

Let go..

Okay 11mm, right here

We have another 11mm on the bottom.

There it goes..

*Chatter*

There it is, and now, there is a 10mm nut

holding on the hot wire and an electrical connector

Oh this has got to be a 13mm.

Now there is an electrical connector

There it is! And then just fish it out

And... I don't know if you can hear that

But this was making a lot of noise

Now for the new one.

This is the new one, nice and quiet.

Plug in the electrical connector

And then

...get it down there first.

And now for the...positive cable

Put the nut back on.

Definitely don't want to kill this.. Just snug it.

There

We might need to pull out this sleeve a little bit

There is this sleeve here.

Let's see if I can get a bite on it...

There it is!

Alright.

Alright so now... We have to re-route the belt

It is a good idea to draw a diagram, or have something before hand

But this pretty much all stayed intact so..

There we go! Make sure the belt is in the center of the pullys.

Now check all the pullys, make sure it's on all the pullys in the center... Nothing slipped off..

Okay, Battery goes back on.

You don't want to strip it out.. There we go.

Let's put all the covers back on.

Alright, lets start it up!

Nice and quiet!
