Drive Belt Tensioner on the 2016 Subaru Forester: What You Need to Know

The 2016 Subaru Forester comes equipped with a traditional accessory drive system that relies on a serpentine belt to power various engine components such as the alternator, power steering pump, and air conditioning compressor. At the heart of this system is the drive belt tensioner, a vital component that ensures the correct tension is maintained on the serpentine belt for smooth and efficient operation.

The purpose of the drive belt tensioner on the 2016 Subaru Forester is to keep the serpentine belt tight against the pulleys. Without this tensioner, the belt could slip or become loose, leading to poor performance of essential accessories, potential overheating of the engine, or even complete accessory failure. The tensioner uses a spring-loaded arm with a pulley that presses against the belt, automatically adjusting for belt stretch and wear over time, making sure the belt runs quietly and smoothly.

Maintaining a healthy drive belt tensioner is important for the overall reliability and functioning of the Forester. The tensioner itself is designed to last a long time, but like all mechanical parts, it can wear out or weaken over the years due to constant tension and heat from the engine bay. When the tensioner fails, the consequences usually include belt squealing, slipping, or in worst cases, belt breakage which can leave the vehicle stranded.

When servicing a 2016 Subaru Forester, it's a good idea to have the drive belt tensioner inspected as part of routine maintenance. Mechanics typically check for signs of wear such as a loose or wobbly pulley, unusual noises like squeaking or grinding, or visible cracks in the tensioner arm or pulley. Another sign to watch out for is frequent belt slippage or the belt looking glazed and worn. Replacing the drive belt tensioner is often done alongside the serpentine belt itself since both wear out around similar intervals and replacing them together is cost-effective.

Tips for maintaining the drive belt tensioner on the 2016 Subaru Forester include:

• Inspect the tensioner every 60,000 to 100,000 kilometres or according to Subaru's service schedule.
• Listen for squealing noises at engine start or during acceleration, as this can be a sign the tensioner's spring is weak or the pulley bearings are failing.
• Observe the belt for signs of uneven wear, cracks, or glazing which suggests the tensioner isn't keeping proper pressure.
• Have the tensioner pulley checked for smooth rotation and no lateral play by a qualified mechanic.
• Replace the tensioner at the same time as the serpentine belt to avoid extra labour costs and ensure optimum belt life.

Replacing the drive belt tensioner on the 2016 Forester is relatively straightforward but does require the correct tools, such as a serpentine belt tool or wrench to relieve tension safely. Subaru's tensioner designs typically have a square hole or bolt for a tool to rotate the arm and ease the belt off. It's always best to follow the factory repair manual or guidelines to avoid damaging the belt or other components. Also keeping an eye on belt alignment during reinstallation helps prevent premature wear and noise.

Many Subaru Forester owners find that by keeping the drive belt tensioner in good shape, their vehicle runs quieter and accessory systems perform reliably for years. Since a worn tensioner often precedes belt failure, a timely replacement can save headaches and costly repairs down the track. It's one of those small components that quietly does a big job, ensuring your Forester's engine accessories get the power they need without a hitch.

Overall, the 2016 Subaru Forester definitely uses a drive belt tensioner, and taking good care of it is part of smart vehicle ownership. Regular check-ups during servicing and paying attention to any unusual noises can keep the tensioner working as it should, helping you steer clear of roadside surprises and keep the Forester running strong and smooth.
