09-21 Toyota Corolla Alternator Replacement.

Today we have a 2010 Toyota Corolla with the 1.8L 2ZR-FE engine that has a battery light on that is not charging. We walk through the basic diagnostic procedure and determine that the alternator is bad. Replacing this is a fairly simple job that can be done with basic hand tools. This process should be the same on 2009 Toyota Corolla, 2010 Toyota Corolla, 2011 Toyota Corolla, 2012 Toyota Corolla, 2013 Toyota Corolla, 2014 Toyota Corolla, 2015 Toyota Corolla, 2016 Toyota Corolla, 2017 Toyota Corolla, 2018 Toyota Corolla, 2019 Toyota Corolla, 2020 Toyota Corolla, and 2021 Toyota Corolla with the 1.8L engine.

I love those Milwaukee ratchets!

[@automotiveinsight]

Yeah, the long reach are nice!

Do you need a torque wrench at 32 LBS for the bottom 14mm bolt or it doesn't matter? That part wasn't explained but I've seen it mentioned in another video. Wondering which is it.

How do you ensure that the belt tension is correct when installing the new alternator?

[@automotiveinsight]

Technically there is a tension gauge. But I just feel the belt.

For mine, grabbing the belt at middle point between alternator and water pump (I think) and twisting it 90 degrees. There should be a "strong" resistant/tension beyond 90.
