Pulled my alternator today (pain in my Burt didn't have a 9/32 socket for the tiny bolts on the back)
Got everything unbolted and didn't mess with the tensioner, spun it by hand and it sounds kinda rough so I was going to replace the bearings and pully, when I went to unbolt the pully the whole tensioner moved but never moved back. Should I just replace the whole piece? (it's like 60 bucks)
Or is it supposed to be like that

 

I would. It's supposed to be spring loaded.

 

They have been know to stick, If you cant free it up replace it.

 

IIRC, the belt tensioner should be replaced ~75K miles. It's something most people don't bother to replace until the bearing freezes or grinds.

 

**** on it I'll replace it, should I go ahead and do the external regulator while I'm doing stuff? Lol

 

Are you having a voltage issue? The voltage is controlled through the PCM, I believe.

 

Pcm does control it, but I've heard it goes out

 

It does, but, no point fixing something that isn't broke.

 

Preventitive maintenance. lol. But money I can spend on something else the truck needs

Still haven't figured out what that plug goes into. Maybe it goes to a brake controller?

 

I would not call replacing a part that does not need to be replaced preventive maintenance. Lol.
