Parts for your 2020 Mitsubishi Outlander-Drive belt tensioner

Drive Belt Tensioner on the 2020 Mitsubishi Outlander: What You Need to Know

The 2020 Mitsubishi Outlander comes equipped with a conventional internal combustion engine setup where a number of accessories such as the alternator, air conditioning compressor, and power steering pump (if applicable) are driven by a serpentine belt. This belt needs to remain properly tensioned to ensure smooth operation and avoid premature wear or failure, which is where the drive belt tensioner comes into play. Fortunately, the 2020 Outlander does include a drive belt tensioner as part of its engine accessory drive system, so it's worth understanding what it does and how to maintain it for peace of mind on the road.

A drive belt tensioner is basically a spring-loaded pulley designed to maintain the correct amount of tension on the serpentine belt. The belt needs to be tight enough to grip all the accessory pulleys securely but not so tight that it creates unnecessary drag or places excessive load on the components. The tensioner automatically adjusts to accommodate belt stretch and prevent slipping, which helps maintain proper function of the battery charging system, air conditioning, and other belt-driven accessories.

In the 2020 Mitsubishi Outlander, the drive belt tensioner works quietly behind the scenes. Under the bonnet, it looks like a small pulley attached to a spring-loaded arm that presses against the belt. As the engine runs and the belt experiences thermal expansion or wear over time, the tensioner adjusts the pulley position to keep a steady, consistent grip on the belt. Without the tensioner, belts would either be too loose and slip - or become too tight and risk breaking or damaging the accessory bearings.

It's not always the first thing drivers think of when servicing their Outlander. Yet, a properly functioning drive belt tensioner plays a vital role in the longevity and reliability of the car's engine accessories. Over time, the tensioner's internal spring can weaken or the pulley bearings may wear out. This can result in a noisy belt drive system, marked by squealing sounds or belt slippage especially when starting the engine or under load. Left unchecked, a failed tensioner can lead to belt failure which in turn causes loss of power steering assist, battery charging, or air conditioning until the belt is replaced.

For people looking after their 2020 Mitsubishi Outlander, it's a good idea to include a check of the drive belt tensioner during routine servicing intervals. Most service schedules recommend inspecting the accessory belt and tensioner every 60,000 to 100,000 kilometres, though it's always best to refer to the specific maintenance recommendations supplied by Mitsubishi for exact timing.

When the tensioner is inspected, technicians will look for signs of wear such as:

• Excessive play or wobble in the tensioner pulley
• Visible cracks, glazing, or fraying on the serpentine belt
• Unusual noises like squealing or chirping when the engine is running
• Any visible damage or corrosion on the tensioner arm or mounting points

If any of these issues are detected, replacement is usually straightforward and involves removing the belt, swapping out the faulty tensioner with a new genuine or quality aftermarket part, and then refitting the belt with the new tensioner applying correct tension. This isn't typically a labour-intensive job, but it does require the right tools and know-how, so many owners prefer to have this done by a professional mechanic.

Proper belt and tensioner maintenance has several benefits for Outlander drivers:

• Improved reliability of the engine accessory drive system
• Prevention of unexpected breakdowns caused by belt failure
• Better performance of air conditioning and power steering systems
• Longer lifespan for other belt-driven components by maintaining correct tension
• Reduction of annoying noises linked to slipping belts or worn tensioners

It's worth noting that while some modern vehicles might use electronically controlled tensioning systems or even switch to electric accessory drives, the 2020 Mitsubishi Outlander sticks with the traditional spring-loaded tensioner design. The simplicity of this mechanical part makes it reliable and easy to maintain, keeping repair costs down and ensuring consistent performance over the years.

For anyone servicing a 2020 Mitsubishi Outlander or performing their own DIY checks under the bonnet, keep an eye and ear out for any signs of belt or tensioner wear. When replacing the belt or tensioner, using genuine Mitsubishi parts is highly recommended to guarantee compatibility and durability. Also, after replacement, the belt routing should be checked carefully to avoid misalignment which can reduce the life of the new parts.

Some simple tips for owners include occasionally checking the belt for cracks or signs of glazing and listening for any belt squeal during startup or heavy engine loads. If you hear unusual noises or notice performance drops in powered systems like steering or air conditioning, it might be time to get that belt tensioner checked out.

Overall, while it might not be the most glamorous component under the bonnet, the drive belt tensioner on the 2020 Mitsubishi Outlander plays an understated but essential role in keeping the vehicle running smoothly and quietly. Regular checks and timely replacements ensure drivers can enjoy hassle-free motoring without unexpected breakdowns from a snapped belt or failed tensioner.
