How to adjust alternator belt my summer car

Article SummaryX

To put on a new alternator belt, you’ll need to disconnect your car battery and remove the old belt so you can thread the new one through the pulleys.

Start by putting on eye protection and gloves to keep yourself safe as you work. Disconnect the car battery and loosen the auto-tensioner using either a breaker bar or a socket wrench. Once the tension is released, slide the belt off the pulleys.

Get the new alternator belt and run it through the pulleys in the same way as the old belt, snaking it around the alternator pulley last.

Alternator belt too tight

Use a wrench to tighten the bolts on the alternator pulley to increase the tension on the belt. Ensure that there is very little give when you try and wiggle the belt, as this shows the belt is aligned properly on the pulleys.

If the belt has the correct tension, reconnect the car battery. For more information on putting on an alternator belt, like how to know when the belt needs replacing, read on.
