BigBob :

Greetings,

JACUSTOMER-kbj1e3rv- :

hello

BigBob :

You will need to use a 16mm socket, rotate the tensioner arm clockwise (about 14°) and remove the belt from the pulley

BigBob :

Then you will have to remove both the alternator bolts and the wiring, make sure to remove the negative battery cable first.

BigBob :

Let me know if I can help further,

BigBob :

Bob

JACUSTOMER-kbj1e3rv- :

But what about accessing the alternator? It's near the back of the engine compartment and low. any other components require removal?

BigBob :

No other components that I know of. You may have better access through the tire well.

JACUSTOMER-kbj1e3rv- :

I was concerned with motor mounts, transmission, etc.

BigBob :

No it only show 1.5 hours to replace. I have not done one on this engine in a long time, but I think it can be removed without removing the mount.

JACUSTOMER-kbj1e3rv- :

I have ramps and jacks to assist.

BigBob :

Yeah, put it up in the air on the jack stands and see if it will clear the axle.

JACUSTOMER-kbj1e3rv- :

That's the plan at this point.

BigBob :

let me know how it goes

JACUSTOMER-kbj1e3rv- :

ok and thanks!
