Is it time to replace your Toyota's serpentine belt? You might be weighing the options between OEM and aftermarket replacements. But which one truly offers the best value? This guide is here to help you make an informed decision.
In this article, we’ll walk you through the key factors to consider when choosing a replacement serpentine belt. We'll also compare OEM and aftermarket options, and explain why OEM belts are often the superior choice. Keep reading to discover the reasons behind this recommendation.
What Is An OEM Serpentine Belt?
OEM (Original Equipment Manufacturer) serpentine belts are produced by the car manufacturer or its authorized vendors. These belts are exact replicas of the ones that came with your vehicle from the factory. Toyota offers a wide range of OEM serpentine belts, each specifically designed for certain models or small groups of models. For example, the part number 89415-06021 is suitable for various 2013–2019 models, including:
- Avalon
- Camry
- Highlander
- Sienna
What Is An Aftermarket Serpentine Belt?
Aftermarket serpentine belts are made by third-party manufacturers and are not regulated or tested by the original car maker, such as Toyota. The design, dimensions, and materials used in these belts can vary significantly from OEM versions.
Now, let’s take a closer look at three crucial factors that determine the quality and performance of a serpentine belt.
1. The Quality Of The Materials
Serpentine belts may seem simple, but they endure constant stress and high temperatures. They rotate nonstop while the engine is running, which can lead to wear and tear over time. If a belt is made with inferior materials, it can:
- Shrink
- Crack
- Fray
- Break
That’s why it’s essential to choose a belt made with high-quality materials. OEM serpentine belts from Toyota are crafted using reinforced rubber that resists shrinking, cracking, and breaking. On the other hand, many aftermarket belts use cheaper materials, leading to premature failure.
2. The Dimensions
A properly sized serpentine belt is critical for optimal performance. It must match the original equipment (OE) specifications in terms of length, width, and thickness. A belt that doesn’t fit correctly can cause serious issues:
- A belt that’s too tight will wear out quickly.
- A belt that’s too loose may slip, causing pulleys to spin at incorrect speeds.
- A belt that’s too thin could break under stress.
- A belt that’s too thick might fall off the pulleys entirely.
OEM belts are always manufactured to precise OE dimensions. While some aftermarket brands may follow these standards, not all do. Choosing OEM ensures a perfect fit every time.
3. Warranty
Even though belts are relatively inexpensive, it’s wise to choose one that comes with a warranty. A warranty reflects the manufacturer’s confidence in their product. Unfortunately, most aftermarket serpentine belts don’t offer any warranty at all.
Toyota, on the other hand, provides a limited warranty on its OEM serpentine belts—typically 12 months or unlimited miles. This means if your OEM belt fails prematurely, you can get it replaced at no cost.
The Bottom Line
When it comes to performance, cost savings, and longevity, OEM serpentine belts are the clear winner. They’re built to last, fit perfectly, and come with reliable support from the manufacturer.
