Drive Belt Tensioner for the 2016 Subaru Exiga: What You Need to Know

The 2016 Subaru Exiga is fitted with a drive belt tensioner as part of its engine accessory drive system. This component plays a crucial role in keeping the serpentine belt, also known as the drive belt, properly tensioned to ensure all engine accessories function smoothly. In the Exiga, the drive belt tensioner helps maintain correct tension on the belt that powers the alternator, power steering pump, air conditioning compressor, and more.

So, what exactly does a drive belt tensioner do? Simply put, it applies constant pressure on the drive belt to prevent it from slipping or becoming loose. This is important because a slack belt can cause accessories to underperform or fail entirely, leading to problems like battery charging issues, overheating, or loss of power steering assist. On the other hand, a belt that is too tight can place unnecessary strain on both the belt and the accessory pulleys, leading to premature wear or damage.

The tensioner unit on the 2016 Subaru Exiga typically consists of a spring-loaded arm with a pulley that presses against the drive belt. This spring-loaded design allows the tensioner to automatically adjust as the belt stretches or wears over time, giving the system a longer service life and reducing the need for manual adjustments.

When it comes to maintaining the drive belt tensioner on a 2016 Subaru Exiga, regular checks during vehicle servicing can save a lot of headaches down the track. Since the tensioner is always under strain, it can wear out or the internal spring can weaken, which will lead to reduced tension on the belt. Signs of a failing tensioner include squealing noises from the engine bay, visible wear or cracks on the belt, or battery warning lights due to charging problems.

Replacing or servicing the drive belt tensioner is generally straightforward but important. Subaru recommends inspecting the drive belt and tensioner during routine servicing intervals, often during brake fluid changes or major service milestones around 100,000 kilometres. If the tensioner pulley shows signs of wobbling, shock absorption failure, or if the spring loses its tensioning ability, the whole tensioner assembly should be replaced to avoid belt slippage or failure.

Some tips for looking after the drive belt tensioner on a 2016 Subaru Exiga include:

• Regularly inspect the drive belt for cracks, glazing, or fraying
• Listen out for unusual noises like squeaks or chirps during startup or acceleration
• Check the tensioner pulley for smooth rotation without wobbling
• Replace the drive belt and tensioner together if either shows signs of wear

DIY enthusiasts with a bit of mechanical know-how can often replace the tensioner themselves using basic hand tools, but it's essential to follow the specific Subaru service manual guidelines to avoid damaging the belt or other components. Always make sure the engine is cool and the ignition off before attempting any work on the drive belt system. If unsure, having a professional mechanic handle the job is the safest bet.

All up, the drive belt tensioner is a small but vital part of the 2016 Subaru Exiga's engine system. Taking care of it helps maintain smooth operation, protects engine accessories, and keeps the vehicle running reliably. Keeping an eye (and ear) on its condition means avoiding unexpected breakdowns and costly repairs linked to drive belt failure.
