Is it time to replace the serpentine belt on your Toyota? You might be torn between choosing an original equipment manufacturer (OEM) belt or an aftermarket alternative. But which one really provides the best value? This guide aims to clarify the decision-making process. In this guide, we’ll delve into the key factors to keep in mind when purchasing a replacement serpentine belt. We’ll also compare OEM and aftermarket options so you can make an informed choice. Spoiler alert: OEM belts tend to be the superior option. Keep reading to discover why. OEM serpentine belts are manufactured either directly by the vehicle’s original manufacturer or by a certified vendor. This means these belts are exact replicas of the stock belt originally installed in your engine. Toyota offers a wide range of serpentine belts, each designed specifically for certain models or groups of models. For instance, one selection might cater to specific 2013–2019 models, including: On the other hand, third-party companies produce aftermarket serpentine belts. The original manufacturer (Toyota) has no involvement in the creation or quality control of these belts. As a result, the design and dimensions of aftermarket belts may vary from those of their OEM counterparts. Now, let’s discuss the three most critical aspects of a serpentine belt. Though serpentine belts seem simple, they endure immense stress while in operation. These belts spin continuously as long as the engine is running, generating high temperatures in the process. This constant strain can degrade subpar materials, causing issues like shrinking, cracking, fraying, or even breaking. Therefore, it’s vital to choose a belt made from appropriate materials. With OEM serpentine belts, you don’t have to worry about material quality. Toyota carefully designs its belts using reinforced rubber that resists shrinking, fraying, and breaking under pressure. However, aftermarket belts often vary in terms of material quality. Many aftermarket belts fail prematurely due to the use of cheaper materials. The serpentine belt plays a crucial role in keeping your engine running smoothly. Without a properly functioning belt, numerous components within the engine won’t work correctly. Thus, it’s essential to select a belt with precise dimensions—specifically, OE dimensions. A belt that matches the correct length and width will operate at peak efficiency. OEM serpentine belts always adhere to the correct dimensions. Meanwhile, aftermarket manufacturers create belts based on their own specifications. While some may mimic OE dimensions, not all do. To ensure reliability, it’s generally safer to opt for OEM belts. Even though belts are relatively inexpensive, having a warranty adds peace of mind. It demonstrates the manufacturer’s confidence in its product. Unfortunately, many—if not most—aftermarket serpentine belts lack warranty protection. Toyota, however, offers a comprehensive warranty on its OEM serpentine belts. This warranty covers the belt for 12 months or unlimited mileage. Should your OEM belt fail prematurely, you can get it replaced free of charge. When considering performance, cost savings, and longevity, OEM serpentine belts clearly stand out as the superior choice. Not only do they offer unmatched reliability, but they also come with added benefits like precise OE dimensions and warranty coverage.
