Just changed my serpentine belt and got everything back on but my pulleys aren’t spinning now and my brake and battery light are on when I crank my car. not sure what’s happening and this is making my day go worse

 

There's a tensioner you loosened to get the old belt off, tension the belt back up. They are NOT an auto tensioning pulley like Chevy, Subaru, etc. It's the manually tensioned kind that Toyota and Nissan use.

I think you need to watch a few youtube videos on changing serpentine belts on Japanese cars.

 

I figured it out the belt just wasn’t on correctly 😂😂 I got her right though she’s running great now .
