Yaris 2014 LE Hatchback 2-door

Can't get rid of the belt squeak when starting the car.

Used 2 different brands of belt dressing. It goes away for a day, then comes back.

Difficult to tighten the belt the way the system is designed (one has to pull the alternator forward, takes a lot of strength).

Got any suggestions I could try?

I went through the same as I did not believe the posts here about the squeaking belts. My car mechanic was already desperate. I tried 3 belt brands (Continental, Gates and something else). They all squeaked, regardless the tension. Changed the pulleys. Nothing helped.
Then I bought the original Toyota belt. Aaaand... the squeak is gone. Right after the change.

Save your time and bucks and go straight for the Toyota belt.

There is a thing with Toyotas, if you turn the ignition on then IMMEDIATELY start the engine, you'll get alternator squeak.

If you turn the ignition on, wait 3 seconds, THEN start the engine, no squeak.

My guess is extra time for the software to get to the alternator regulation.

This 3 second break did not help me with my squeak. Only the Toyota belt did.
