stuck pulley?

2001 xj stock engine. 141,000k

After some time in the mud and a thorough cleaning my Jeep sat for a week. I just went to start it and the serpentine belt was screeching.

It is not spinning. One of the pulleys is frozen.

Any ideas where to start and what to lubricate? What lubricant, I don't want to affect the belt itself?

Thank you.

Yup. I owe you a 5r

Can it be lubed? I broke it free and it spins but it feels dry. Is a new one necessary?

Lube is not really good for an alternator. It should be fine if it charges at 13.8-14.4 volts and does not squeak or squeal.

Not sure what Thorough may mean but... If you haven"t, Power Wash the engine compartment. Use the:
High Pressure "Soap" choice at the drive in - do it yourself car wash.
(High Pressure Soap comes out Pretty Warm, sometimes very warm, depending on the owner of the establishment. The warm helps a lot to dislodge dried mud and old burnt on grease)
High Pressure "Rinse" comes out Cold - Rinse Only

I pressure wash my vehicles engine compartment and Whole Undercarriage Often and Never have a problem re-starting the engine afterwards (so far).

Thank You,
Bo

It can be loosened but will freeze up again. Sorry but its time for a new alternator.

Of all the things Ive lost
The one I miss most is my mind

Its like a fart in a windstorm
It smells good but thats about it

Everything is working well at the moment. We will see. I wouldn't mind a higher output alternator anyway.

And you've never had an issue with the MAP or TB sensors?

No Sir, no problems with Any Electrical's after the engine power wash.

I Power wash my vehicles Engine Area's and Undercarriage fairly regularly... so far (many years now, 25 or so), not one issue with Any of the vehicles... Ford, Dodge, Chrysler, Jeep (now), Pontiac (a 2000 pontiac grand prix), Chevrolet.

I Think... that the only way a person would have a change in Start Up or Engine Running after power washing their engine is If there is a bad part like... Crack in a plug wire, or crack in any electrical component. The engine might run fine when Dry but when soaked with water, the water would get past the crack in the part and cause misfire or the like.

after Power Washing... let the engine bay area dry out a bit and then spray Armorall on Everything. Let that dry. Next day lift the hood and your engine bay will look like new again (or almost new). I usually drive the vehicle right after the Armorall and let it dry that way.

Same with the Fender Wells and Undercarriage.

Thank You,
Bo
