Volvo S60 Serpentine Belt Guide: 2011-2017 Models
Everything you need to know about choosing and replacing the serpentine belt on your 2011-2017 Volvo S60.
- A failing serpentine belt can cause catastrophic engine damage on this S60 if it tangles with the timing belt.
- Proactively replace the belt, tensioner, and idler pulleys together every 50,000-75,000 miles to avoid failure.
- High-quality aftermarket brands like Continental, Gates, and Dayco are excellent, reliable alternatives to OEM parts.
- Symptoms like squealing noises, visible cracks on the belt, or a battery warning light should be addressed immediately.
Is Your Serpentine Belt Failing?
A failing serpentine belt can cause serious problems, so it's important to recognize the warning signs. Look and listen for these common symptoms:
- Squealing or Chirping Noises: A high-pitched squeal, especially when you start the engine or turn on the A/C, is a classic sign of a worn or loose belt.
- Visible Wear: A visual inspection can reveal a lot. Look for cracks, fraying, glazing (a shiny surface), or missing ribs on the belt. Any visible damage means it's time for a replacement.
- Accessory Problems: Since the belt powers many components, you might notice dimming headlights (alternator issue), difficulty steering (power steering issue), or your A/C not blowing cold.
- Battery Warning Light: If the belt isn't spinning the alternator correctly, your battery won't charge, triggering the battery warning light on your dashboard.
A Critical Known Issue: Belt Failure and Engine Damage
For this generation of Volvo S60, a failed serpentine belt can be catastrophic. There is a known issue where a shredding or broken serpentine belt can get pulled behind the crankshaft pulley and tangled in the timing belt. This can cause the timing to jump, leading to the pistons hitting the valves and resulting in severe, often irreparable, engine damage. This makes proactive replacement of the serpentine belt, tensioner, and idler pulleys extremely important.
Choosing the Right Aftermarket Belt
For a part this critical, quality is key. Fortunately, top-tier aftermarket brands are often the original equipment (OEM) suppliers for Volvo, so you can get the same quality without the dealership price tag. Brands like Continental, Dayco, and Gates are all excellent choices for your S60.
- Continental: Often considered a top choice for European vehicles, Continental belts are known for their quiet operation and durability. They are a frequent OEM supplier.
- Gates: Gates is another highly respected brand with a reputation for making strong, reliable belts that meet or exceed OEM specifications.
- Dayco: Dayco offers quality belts that are a dependable choice for replacement and are trusted by many professional mechanics.
You can't go wrong with any of these three brands. The choice often comes down to price and availability. For the S60, 🎬 See a comparison of the best serpentine belt brands. an OEM belt from the dealer and a premium aftermarket belt from one of these brands are often identical in quality.
Pro Tip: Replace the Tensioner and Idlers Too
The serpentine belt tensioner and idler pulleys have a similar lifespan to the belt itself. The tensioner keeps the belt tight, and a failing one can cause noise, premature belt wear, or even cause the new belt to snap. It is strongly recommended to replace the belt, tensioner, and any idler pulleys as a kit. This ensures all components are fresh and prevents a worn-out tensioner 🎬 Watch this guide on replacing your serpentine belt tensioner. from destroying your new belt.

Frequently Asked Questions
When should I replace my S60's serpentine belt?
Volvo recommends a long service interval, sometimes up to 150,000 miles, but given the risk of engine damage from a failed belt, a more conservative approach is wise. Many experts and owners recommend inspecting the belt at every oil change and replacing it, along with the tensioner, every 50,000 to 75,000 miles as preventative maintenance.
Is this a DIY job?
For a moderately experienced DIYer, yes. The difficulty varies by engine. On some models, access is tight, and you may need to remove the passenger-side wheel and fender liner. The T6 engine can be more complex, sometimes requiring the removal of other components to gain access. You will need a specific tool (like a long-handled ratchet or breaker bar with a Torx or socket head) to release the tensioner.
What's the difference between the T5 and T6 engine belt replacement?
The 2011-2017 S60 came with different engines, including 5-cylinder (T5), 6-cylinder (T6), and later 4-cylinder (Drive-E T5) options. The belt routing and replacement procedure can be different for each. For example, the T6 replacement can be more involved, with some guides suggesting the need to move the A/C compressor to route the belt. Always ensure you have the correct belt and diagram for your specific engine.
Are there any recalls for the serpentine belt?
As of now, there are no specific NHTSA recalls for the serpentine belt itself on the 2011-2017 Volvo S60. However, there have been recalls for the front seat belts (the safety restraints inside the car), which can cause confusion. The critical issue of the serpentine belt failing and causing timing belt damage is a known problem discussed widely in owner forums and by mechanics, but it has not resulted in an official recall.
