A Guide to the Serpentine Belt for the 2016 Scion iM
Keep your Scion iM's engine running smoothly by understanding this critical wear-and-tear part.
- The serpentine belt is critical; if it breaks, your Scion iM will overheat and lose electrical power, leaving you stranded.
- Inspect the belt for cracks and listen for squealing noises. Plan for replacement around 100,000 miles.
- Aftermarket brands like Continental, Dayco, and Gates are high-quality, reliable alternatives to the more expensive OEM part.
- When replacing the belt, it is a good practice to also inspect the belt tensioner and pulleys for wear.
Is Your Scion iM Serpentine Belt Failing?
A serpentine belt is a wear item, meaning it will eventually need to be replaced. For the 2016 Scion iM, the typical lifespan is around 100,000 miles, but it should be inspected for wear during routine service. Ignoring a failing belt can leave you stranded.
Common signs of a worn-out belt include:
- Squealing Noises: A high-pitched squeal from the engine bay, especially on cold starts or during sharp turns, is the most common symptom of a slipping or worn belt.
- Visible Wear: Look at the belt. If you see cracks, fraying, glazing (a shiny, smooth surface), or missing ribs, it's time for a replacement.
- Accessory Failure: If your air conditioning blows warm air, your battery light comes on, or your engine temperature gauge starts to rise, the belt may have failed. A complete belt failure will cause the engine to overheat and the battery to die quickly.
Check the Tensioner, Too
The serpentine belt is kept tight by a spring-loaded belt tensioner. These tensioners can also wear out, leading to improper belt tension and noise. If you're replacing a belt with significant mileage, it's wise to inspect the tensioner and pulleys for noise or wobble and replace them at the same time to avoid a future failure.
Choosing the Right Aftermarket Serpentine Belt
For a straightforward part like a serpentine belt, aftermarket options from reputable brands offer quality that is equivalent to the Original Equipment Manufacturer (OEM) part. The key is to stick with trusted names. The brands available—Continental, Dayco, and Gates—are all top-tier manufacturers that supply parts to automakers directly. You can confidently choose any of these brands based on price and availability.
- Continental: A major OEM supplier, often praised for quiet operation and durability.
- Dayco: Another well-respected brand known for making reliable and long-lasting belts.
- Gates: A leading name in belts and hoses, Gates is a go-to choice for many professional mechanics and is known for its high-quality construction.
Pro Tip: All modern belts are made from a durable EPDM rubber compound designed to resist heat and cracking. The quality difference between these top brands is minimal for a daily-driven vehicle like the Scion iM. The most important factor is correct installation.
