How to Replace Belts on a 2020 Outback

Tools Required: 

✔ Serpentine belt tool or breaker bar 

✔ Socket and ratchet set 

✔ Work light 

✔ Gloves 

✔ New OEM belt

Installation Steps:

  1. Locate the Belt Routing Diagram under the hood or in the service manual.

  2. Use a Belt Tensioner Tool to relieve tension from the belt system.

  3. Remove the Old Belt, inspecting it for cracks, fraying, or glazing.

  4. Route the New Belt carefully following the diagram and pulley layout.

  5. Reapply Tension and check belt seating on all pulleys.

  6. Start the Engine to ensure smooth, noise-free operation.

Pro Tip: Inspect the belt tensioner and idler pulleys during replacement—these components often wear out along with the belt.
