Scion FR-S Accessory Drive Belt Guide for 2013-2016 Models
Learn how to spot a failing accessory belt on your FR-S and choose the right aftermarket part for your car.
- A squealing noise is the first sign your belt may be failing; inspect it for cracks or fraying.
- For a stock engine, Bando is a reliable, OEM-quality aftermarket replacement.
- The Kraftwerks belt is a specialty part ONLY for cars with a Kraftwerks supercharger and will not fit a stock FR-S.
- If the belt breaks, you must stop driving immediately to prevent severe engine damage from overheating.
Is Your FR-S Making a Squealing or Chirping Noise?
A high-pitched squeal from the engine bay, especially on cold mornings, is the most common sign of a worn accessory drive belt. This noise happens when the belt's rubber surface becomes hard and glazed, causing it to slip on the metal pulleys. You may also notice the noise gets louder when you turn on the A/C. While noise is the first symptom, you should also perform a visual inspection. Look for cracks, fraying along the edges, or missing chunks from the ribbed side of the belt. If the belt looks shiny instead of a dull black, it's likely worn and needs replacement.
Don't Confuse Belt Squeal with "FR-S Crickets"
Many FR-S owners report a chirping noise often called "crickets." This is a known issue related to the high-pressure fuel pump and is different from the steady squeal of a slipping belt. A failing belt tensioner or idler pulley can also cause grinding or rattling noises, so it's important to identify the source of the sound.
Choosing the Right Aftermarket Belt: Standard vs. Performance
When shopping for a new accessory belt, it's critical to buy the correct one for your car's setup. For a stock, non-modified Scion FR-S, you need a standard replacement belt.
- Bando: Bando is a well-regarded brand that is an original equipment manufacturer (OEM) for many Japanese car brands. Choosing a Bando belt is a safe and reliable option that provides quality equivalent to the original part that came on your car from the factory.
- Kraftwerks Performance Group: The Kraftwerks belt is NOT for a standard FR-S. It is a wider, more durable belt designed specifically for cars that have a Kraftwerks supercharger kit installed. It will not fit on a stock engine setup. Do not purchase this belt unless you have this specific supercharger.
Known Issues, Recalls, and TSBs
There are no safety recalls from the NHTSA for the accessory drive belt on the 2013-2016 Scion FR-S. However, a major recall was issued for the engine valve springs on 2013 models, which required significant engine work. While unrelated to the belt, a shop performing this recall may recommend replacing a worn belt at the same time. No other official Technical Service Bulletins (TSBs) exist for the belt itself, aside from information distinguishing the common fuel pump "cricket" noise from belt squeal.
| Part Type | Estimated Cost |
|---|---|
| New OEM Belt | $45 - $65 |
| New Aftermarket Belt (Standard) | $40 - $60 |
| Shop Labor | $75 - $125 |
Frequently Asked Questions
How often should I replace my FR-S accessory belt?
There is no strict mileage interval, but it's a good practice to inspect the belt at every oil change. Many belts last 50,000 miles or more, but they should be replaced at the first sign of cracking, fraying, or persistent noise.
Is replacing the accessory belt a DIY job?
Yes, for most home mechanics, this is a straightforward job. It requires a 14mm wrench to release the spring-loaded tensioner, allowing you to slip the belt off and on. The entire process typically takes less than an hour.
What happens if the accessory belt breaks while driving?
If the belt breaks, your engine will lose power to the alternator and water pump. The battery will stop charging, and the engine will quickly overheat. You will need to pull over immediately and have the vehicle towed to avoid catastrophic engine damage.
Can I use a Kraftwerks belt on my stock FR-S?
No. The Kraftwerks belt is designed only for their supercharger systems. It is a different width and length and will not work on a standard, non-supercharged engine.
