S60 T5 Serpentine Belt Replacement: DIY Difficulty & Tools Needed

Vehicle: 2020 Volvo S60 T5 Momentum

Hi all,

I've got a 2020 Volvo S60 T5 (FWD) and I'm approaching 60,000 miles. I'm thinking about replacing the serpentine belt as preventive maintenance. I'm fairly handy with car repairs, but I haven't tackled a Volvo belt before.

How difficult is this job on the S60 T5? Are there any special tools required beyond a standard socket set and a breaker bar? Any tips or common pitfalls I should be aware of? I've heard some Volvo engines can be a bit tight to work in. Thanks in advance!

Replacing the serpentine belt on your 2020 Volvo S60 T5 is a manageable DIY task for someone with moderate mechanical experience. While the engine bay can be a bit cramped, it's generally accessible.

Difficulty & Tools:

  • Difficulty: Moderate. The main challenge is often gaining enough leverage on the tensioner and routing the new belt correctly.
  • Tools Needed:
    • Socket Set: You'll need a socket (often 14mm or 15mm, verify for your specific engine) that fits the tensioner bolt.
    • Breaker Bar or Long Ratchet: Essential for applying enough leverage to release the tensioner.
    • Serpentine Belt Tool (Optional but Recommended): A specialized serpentine belt tool with various adapters can make the job much easier, especially in tight spaces, by providing better reach and leverage.
    • Diagram: Have a diagram of the belt routing handy before you start. Take a photo of the current routing as a backup.
    • Flashlight: For better visibility in the engine bay.

Procedure Overview:

  1. Safety First: Ensure the engine is off and cool. Disconnect the negative battery terminal as a precaution.
  2. Locate Tensioner: Identify the automatic belt tensioner. It will have a square drive or a bolt head for a socket.
  3. Release Tension: Use your breaker bar/ratchet on the tensioner bolt/square drive to rotate it and relieve tension on the belt. You may need to hold it in place while you slip the old belt off.
  4. Remove Old Belt: Carefully remove the old belt from all pulleys.
  5. Inspect Pulleys: While the belt is off, manually spin each pulley (alternator, AC compressor, power steering pump, idler pulleys) to check for any play, roughness, or noise. This is a good time to replace any worn idler or tensioner pulleys.
  6. Route New Belt: Following your diagram, carefully route the new belt around all pulleys, leaving the tensioner pulley for last. Ensure the ribbed side is on ribbed pulleys and the smooth side on smooth idler pulleys.
  7. Apply Tension: Once the belt is mostly routed, use your tool to again release the tensioner, allowing the new belt to slip onto the tensioner pulley. Slowly release the tensioner.
  8. Verify Routing: Double-check that the belt is seated correctly on all pulleys and that the routing matches your diagram.

When to See a Shop:

  • If you're uncomfortable with the process or lack the necessary tools.
  • If you encounter unexpected difficulties or can't get the new belt routed correctly.
  • If you notice any unusual noises from the pulleys (squealing, grinding) after replacing the belt, which could indicate a failing accessory or tensioner.
