In this ultimate can am outlander 2015 guide, we’ll cover the common problems you might face (and how to fix them), a rock-solid DIY maintenance checklist, popular performance mods that actually work, and even some tips on riding responsibly. Let’s get those hands dirty.

Why the 2015 Can-Am Outlander is Still a Trail King

Before we dive into the nuts and bolts, let’s appreciate what makes this machine special. The 2015 model year sits in a sweet spot, offering modern features without the overly complex electronics of newer ATVs. It’s a platform that rewards a hands-on owner.

The core benefits of can am outlander 2015 models stem from a few key features that were ahead of their time.

Legendary Rotax V-Twin Power

Whether you have the 500, 650, 800R, or the monster 1000, the heart of your Outlander is a potent Rotax V-Twin engine. These powerplants are known for their incredible torque and reliability, provided you treat them right.

They deliver smooth power for slow-speed crawling and a thrilling punch when you hammer the throttle on an open trail.

Advanced Handling and Control

Can-Am’s Tri-Mode Dynamic Power Steering (DPS) was a game-changer. It allows you to adjust steering feel on the fly, reducing fatigue on long rides. Pair that with the Visco-Lok QE auto-locking front differential, and you have a machine that claws for traction exactly when you need it, without you having to do a thing.

This combination makes the Outlander feel both stable at speed and nimble in tight, technical sections.

The Can Am Outlander 2015: Common Problems and Smart Fixes

No machine is perfect, and after years of service, the 2015 Outlander has a few well-documented quirks. Knowing what to look for is half the battle. This is where you can save a ton of money by diagnosing issues yourself.

Issue 1: Overheating on Slow Trails

One of the most frequent common problems with can am outlander 2015 models is overheating, especially in mud or during slow, technical riding. The cause is almost always related to airflow.

The Cause: The radiator gets caked with mud and debris, blocking air. In other cases, the radiator cooling fan or its relay fails.
The DIY Fix: First, give your radiator a thorough but gentle cleaning. Use a garden hose (not a high-pressure washer, which can bend the fins) to spray from the back towards the front. For stubborn grime, use a soft brush and a quality degreaser. To check the fan, let the ATV idle until it reaches operating temperature. If the fan doesn’t kick on, use a multimeter to check the fan relay and wiring for power.

Issue 2: Electrical Gremlins and DPS Faults

Seeing a “CHECK ENGINE” or “DPS FAULT” light can be nerve-wracking. Often, the root cause is simpler than you think and relates to the electrical system’s health.

The Cause: The most common culprits are a weak battery, a failing voltage regulator, or corroded ground wire connections. The Outlander’s systems are very sensitive to voltage.
The DIY Fix: Start with the basics. Ensure your battery is fully charged and the terminals are clean and tight. Next, locate the main ground points on the frame (consult your service manual) and clean them with a wire brush until they are shiny. Apply a thin layer of dielectric grease to prevent future corrosion. If problems persist, a faulty voltage regulator is a likely suspect.

Issue 3: Drivetrain Noises and Vibrations

Clicks, pops, and whines from the drivetrain are signs of wear that you shouldn’t ignore. Catching them early prevents catastrophic failures on the trail.

The Cause: Clicking sounds when turning are a classic sign of a worn CV joint in your axle shafts. A humming or grinding noise that changes with speed often points to a bad wheel bearing.
The DIY Fix: To check a wheel bearing, safely jack up one corner of the ATV and try to wiggle the wheel from top-to-bottom and side-to-side. Any significant play means the bearing is shot. Replacing wheel bearings and CV joints are manageable DIY jobs with the right tools, like a bearing press kit and snap-ring pliers.

Your Essential Can Am Outlander 2015 Care Guide: A DIY Checklist

Consistent maintenance is the single most important thing you can do for your ATV. Following this can am outlander 2015 care guide will dramatically extend its life and prevent those common problems we just discussed.

H3: Engine Oil & Filter Change (Every 50 hours / 6 months)

This is non-negotiable. Clean oil is the lifeblood of your Rotax engine.

Warm up the engine for a few minutes to get the oil flowing.
Place a drain pan under the engine and remove the drain plug. Be ready with a new crush washer.
Remove the oil filter cover and replace the old filter with a new one (e.g., a HiFlo HF152). Remember to replace the o-rings.
Reinstall the drain plug and torque it to spec (check your manual, usually around 18-20 ft-lbs).
Refill with the correct amount of a quality oil like XPS 5W-40 Synthetic Blend. Do not overfill! Check the level using the dipstick as per the owner’s manual instructions.

H3: Air Filter Inspection (Before Every Ride)

A dirty air filter is a quick way to kill engine performance and cause long-term damage. Your inspection frequency depends on your riding conditions—dusty trails mean more frequent checks.

Cleaning: Carefully remove the foam air filter. Clean it with a dedicated air filter cleaner and warm water. Let it dry completely.
Oiling: Once dry, apply a quality foam air filter oil evenly. Squeeze out the excess until it’s tacky but not dripping. This is one of the most important can am outlander 2015 best practices for engine longevity.

H3: Drivetrain Fluid Check (Every 100 hours / Annually)

Your front and rear differentials and gearbox have their own oil that needs love, too. These fluids break down over time, especially if you ride through water.

Check the fluid levels using the fill plugs on each component. When it’s time to change them, use the manufacturer-specified fluid, typically a 75W-90 or 75W-140 synthetic gear oil.

How to Can Am Outlander 2015: Popular Upgrades for Performance & Utility

Once you have the maintenance dialed in, it’s time for the fun stuff. The Outlander is a fantastic platform for modifications. Here are a few smart upgrades that deliver real results.

Tires & Wheels

The single biggest performance upgrade you can make. The stock tires are okay for general use, but specialized tires will transform your machine. Consider a 26-inch or 27-inch tire for a great balance of improved ground clearance and minimal power loss.

For Mud: Look at aggressive tread patterns like the ITP Cryptid or Maxxis Zilla.
For Trails/Rocks: An all-terrain radial like the Maxxis Bighorn 2.0 or GBC Dirt Commander is an excellent choice.

Clutch Kit

If you install larger, heavier tires, a clutch kit is one of the best supporting can am outlander 2015 tips. It recalibrates your CVT system to work with the increased rotating mass, restoring lost acceleration and improving belt life. Brands like EPI and Dalton Industries make excellent, easy-to-install kits.

Skid Plates and Protection

The factory plastic “skid plates” offer minimal protection. If you plan on riding in rocky terrain, a full set of aluminum or UHMW (Ultra-High-Molecular-Weight polyethylene) skid plates is a must-have. They will protect your engine case, differentials, and A-arms from expensive damage.

Sustainable & Eco-Friendly Can Am Outlander 2015 Best Practices

Being a responsible off-roader means protecting the trails we love to ride. Integrating some sustainable can am outlander 2015 habits into your routine is easy and makes a huge difference.

Responsible Fluid Disposal

Never, ever dump used oil, coolant, or other fluids on the ground or down a drain. Collect all your used fluids in a sealed container. Most auto parts stores (like AutoZone or O’Reilly) will accept used motor oil for recycling free of charge.

Wash Your Rig Smartly

After a muddy ride, wash your ATV on a grassy area or at a designated car wash if possible. This prevents mud, oil, and other contaminants from running directly into storm drains and local waterways. Using a biodegradable, eco-friendly can am outlander 2015-approved soap is even better.

Tread Lightly on the Trails

This is the golden rule of off-roading. Stay on marked trails, avoid creating new bypasses around obstacles, and cross streams only at designated points. This minimizes erosion and protects the natural habitat for everyone to enjoy.

Frequently Asked Questions About the Can Am Outlander 2015

What is the best engine oil for a 2015 Can-Am Outlander?

The manufacturer recommends a 5W-40 synthetic blend oil, like BRP’s own XPS brand. However, any high-quality 5W-40 synthetic oil from brands like Mobil 1, Amsoil, or Rotella T6 that is rated for wet-clutch use (JASO MA/MA2) will work excellently.

How often should I service my 2015 Outlander?

A basic service (oil change, air filter clean, general inspection) should be done every 50 hours or 6 months, whichever comes first. A major service, including changing differential fluids and inspecting the clutch, is recommended every 100-200 hours or annually, depending on your riding intensity.

What does “Limp Mode” mean on a Can-Am?

Limp Mode is a protective feature that drastically reduces engine power to prevent serious damage when the ECU detects a critical fault. Common triggers include severe overheating, low oil pressure, or a major sensor failure. If your machine goes into limp mode, stop immediately, let it cool down, and check for obvious issues like low fluid levels before attempting to ride it slowly back.

Can I put larger tires on my stock 2015 Outlander?

Yes, but with limitations. You can typically go up one or two sizes (e.g., from 25″ to 26″ or 27″) without any modifications. Going larger than that will likely require a lift kit to prevent rubbing and a clutch kit to compensate for the added weight and gearing change.

The can am outlander 2015 is an incredible machine that will serve you well for years to come with the right care. By understanding its systems and committing to regular, hands-on maintenance, you’re not just a rider—you’re a true owner. You’ve got the knowledge now.

Grab your tools, stay safe on the trails, and enjoy every moment of the ride!
