Replace the alternator in your Toyota Corolla 1.8 l and eliminate the squeal!

For months now, my son has been complaining about a squealing noise when he started his 2010 Toyota Corolla. He took it to Toyota and they said the squeal was coming from the water pump. I changed the water pump but the squeal remained. My back yard mechanic diagnosis was that the bearing in the alternator was wearing out causing the squeal.
I was correct. In this video I will show you how to change out an alternator in a 2008-13 Toyota Corolla 1.8l.

A good video with very helpful details for DIYers. You should disconnect the negative terminal as it is not safe to disconnect the positive terminal while keeping negative terminal connected - There are many RUclips videos explaining why.

I added a new belt when I did mine and I didn’t even need to tighten the belt tensioner as much as you did. Just tightening the alternator bolts is enough to tighten the belt

We’re you get the alternator?

[@Sweaty__Sheep]

Mine squeaks like a squeaky bed when cold. Hard to tell whether it is belt or the alternator itself.

Good morning Scott! Any reason why you removed the positive instead of the negative terminal? Or does it really not matter? Thank you Sir in advance.

[@ScottsGarage17]

I don't think it matters. It might be safer removing the negative. Sometimes in removing the positive you wrench or rachet can touch the frame causing it to arc. I am not a professional mechanic, however.

I just replaced mine and now it squeak's just like yours only when starting. You think maybe the belt is too tight or loose?

The drive cycle ,anyway, you gonna ruin the ECM of the car.Because you unplug the battery terminal.
