WHAT THE CRAP!?
>.<
Well I pulled the cable on Sunday night and it died.
Charged battery and drove down to body shop for dry area to work on electrical stuff ... it died alright ... like bad ... thank goodness it was downhill to the shop so I coasted ^_^

Alternator, belt, tensioner pulley, idler pulley, oil change and fog light replacement all done. No squeak and battery stays at 14V or so.
I am one happy camper!

I have a few photos ... and I meant to do a video of the removal and installation (fast forward video) for the tech section but I forgot the tripod >.< Brilliant idea but fouled by bad weather.
She had died on the way to shop but thank God cause I got her to the downhill and I coasted the rest of the way.

I must admit the belt was no problem at all - super easy so I did not use the idler pulley tip. I just stuck my 3/4" socket wrench in the tensioner and that was that.

A tip though. I spent 30 minutes feeling out the old alternator and staring at the new alternator's mount holes. The old one was SO Tight in that I swore there was hidden bolt some where. Anyways tip ... use a pry bar and gentle pry on both sides of the alternator and it will pop out with easy.

For reference for folks wondering how long it takes to do alternator, tensioner, idler pulley and belt ... 2 hours if you pro at taking out the shroud hah ha.

Hi. This is right up the alley of the conversation you were having here. I replaced my alternator and when I put the tensioner back on, it failed and the spring broke. I replaced the tensioner and the idler pulley and now I have a really annoying squeak almost like a chirp chirp. It does not change with RPM's. It does go away after a while when you are driving it. Is this coming from my water pump?

another good thing to check on our vans are the power steering pump bolts. They tend to back out causing slack in belt that may be causing alot of noise.

I'll check my power steering pump bolts. My mystery squeak is elusive. New Belt, idler, tensioner and pulley. New water pump and fan clutch. It squeaks under load when driving or when in park and revving the engine. 240,000 miles. Original alternator and power steering pump. The squeak is present with or without the A/C on. Not sure what to try next. Seems to be from the lower side of the engine, but I cannot tell if from the front or rear. I am also having transmission troubles with erratic shifting and an erratic speedometer. Such strange goings on.

I took a short video (sound) this morning of my mystery squeak. Not sure how to upload it though. Van was cold. Squeak was present from startup. I will check the power steering pump bolts and motor mounts this weekend, if I can, and post an update.
