Thanks so much for such a great and easy to follow video. Saved me a ton of time replacing an alternator for the first time on a cold dark night when the old one went out unexpectedly. Will check out your other videos for other needed repairs. Awesome job!

I just did this job tonight August, 14th, 2024 and the belt was a PITA to get back on all the pulleys and whatever else the belt needed to be on. The van started back up weakly, as if it was grtting used to the new adjustments, then it shut off, with the dash lights on. I then turned the van back on and everything was all-right. Normal. The thermostat on the dashboard cluster behaved normally until going down the road I noticed that that particular dash needle was all the way at the bottom and the check gages light was illuminated, I pulled over and checked under the hood and there was still coolant in the clear overflow canister. So everything is good under the hood, just gotta research this problem further.
