Drive Belt Tensioner on the 2017 Subaru Exiga: Purpose and Maintenance

The 2017 Subaru Exiga uses a conventional accessory drive system that includes a drive belt tensioner. This small but important component plays a crucial role in keeping the drive belt operating smoothly and efficiently. In vehicles like the Exiga, the drive belt tensioner maintains the proper tension on the serpentine belt, which powers various accessories such as the alternator, power steering pump, and air conditioning compressor.

Without the drive belt tensioner, the belt would become loose, slip off pulleys, or fail to transfer power effectively to these accessories. That would soon cause performance issues and could potentially leave the driver stranded. Subaru designs the Exiga's drive belt tensioner to apply consistent pressure, effectively compensating for belt wear and stretching over time. This ensures the belt stays tight and the accessories run smoothly.

During routine servicing of the 2017 Subaru Exiga, the drive belt tensioner should be inspected alongside the drive belt itself. Even though the tensioner is built to last, it can develop problems. Common issues like a failing tensioner can lead to squealing noises, belt misalignment, and accelerated belt wear. Ignoring these signs might lead to more expensive repairs down the track, such as replacing the belt, pulleys, or even accessory components.

Normally, the tensioner includes a spring-loaded arm that presses against the belt. Over time, the spring can weaken, or the tensioner's pulley can wear out, causing the tension to drop. If a mechanic detects any wobbling or roughness in the pulley or a reduction in spring force, it's a clear sign that the tensioner needs replacement. Also, visible cracks or damage to the tensioner arm recommend replacement to keep the belt system in top condition.

Many Subaru owners might wonder if they can replace the drive belt tensioner themselves. The good news is that it's usually a straightforward job, provided you have basic mechanical skills and the right tools. Typically, the tensioner is secured with a single bolt, and releasing the tension to remove the belt often involves using a special tool or a suitable length spanner. However, for the best outcomes, it's recommended to have it inspected and replaced by a qualified mechanic during scheduled servicing intervals.

The recommended interval for checking the drive belt and tensioner on the 2017 Subaru Exiga usually aligns with the belt replacement schedule, typically every 80,000 to 100,000 kilometres. However, it's a good idea to have it looked at more regularly if the car is used in harsh conditions, such as extreme heat, dusty environments, or regular stop-start city driving. These factors can accelerate wear on both the belt and tensioner.

When replacing the drive belt tensioner, it's smart to change the serpentine belt at the same time. This ensures optimal compatibility and can prevent future issues caused by an ageing belt rubbing against a new tensioner. Subaru parts specialists recommend using genuine or high-quality aftermarket components to maintain reliability and longevity.

Overall, the drive belt tensioner is a vital component to keep the 2017 Subaru Exiga running at its best. Maintaining proper tension on the serpentine belt means smoother accessory operation, reduced noise, and fewer unexpected breakdowns. Regular inspection, timely maintenance, and replacement when necessary will keep the engine accessories powered and the vehicle running smoothly for many kilometres to come.
