What Makes the 2015 Can-Am Outlander 800 a Modern Classic?
Before we grab the wrenches, it’s worth appreciating what makes this specific model so special. It’s not just another ATV; it hit a sweet spot in power, handling, and features that still makes it a sought-after machine today. Understanding its core components helps you appreciate the benefits of 2015 can am outlander 800 ownership.
The Heart of the Beast: The Rotax 800R V-Twin
The soul of this machine is its 799.9cc, liquid-cooled Rotax V-twin engine. It was renowned for its impressive torque curve and exhilarating power delivery. This isn’t a peaky, high-revving engine; it delivers grunt right off the bottom, making it perfect for rock crawling and mudding.
Revolutionary Handling: The G2 Chassis and Tri-Mode DPS
Can-Am’s Surrounding Spar Technology (SST) G2 frame was a game-changer. It provides superior structural integrity while keeping the machine surprisingly nimble. Paired with the Tri-Mode Dynamic Power Steering (DPS), riders could choose their level of steering assistance (MIN, MED, MAX) to match the terrain, reducing fatigue on long rides.
A Trim for Every Rider
The 2015 model year offered several packages, each tailored for a different purpose:
- Base/DPS: The solid, no-frills foundation with the option for power steering.
- XT: The workhorse. This package added a hefty 3,000-lb WARN winch, heavy-duty bumpers, and cast-aluminum wheels with Carlisle ACT radial tires.
- XT-P: The performance package. It included everything from the XT plus fully adjustable FOX Podium X performance shocks, beadlock wheels, and a signature color scheme.
Your Essential 2015 Can Am Outlander 800 Care Guide
Consistent maintenance is the single most important factor in keeping your Outlander reliable. Following these 2015 can am outlander 800 best practices will save you from costly repairs and ruined weekends. This is your fundamental care guide.
The Heartbeat: Engine Oil & Filter
Clean oil is non-negotiable. The Rotax engine works hard, and its oil does, too. You’ll need about 2.1 quarts of XPS 5W-40 Synthetic Blend Oil (or equivalent Jaso MA rated oil) and a new oil filter.
- Warm up the engine for a few minutes to get the oil flowing.
- Place a drain pan under the engine and remove the 17mm drain plug. Be careful, the oil will be hot.
- While it drains, remove the oil filter cover (three 8mm bolts) and pull out the old filter.
- Once drained, clean and reinstall the drain plug. Pro Tip: Always use a new crush washer if possible to prevent leaks.
- Lubricate the O-ring on your new filter with fresh oil and install it. Re-secure the cover.
- Refill with the correct amount of oil, checking the dipstick as you go. Don’t overfill!
Keeping it Cool: Coolant System Checks
Overheating is a V-twin’s worst enemy. Regularly check the coolant level in the overflow reservoir located under the front plastic panel. Only top it off with a 50/50 mix of distilled water and an ethylene glycol-based coolant recommended for aluminum engines.
Drivetrain Diligence: Differentials & Gearbox
Your front/rear differentials and gearbox need love, too. Check the fluid levels using their respective fill/check plugs. Use the manufacturer-specified fluid, typically a 75W-90 synthetic for the diffs and 75W-140 for the gearbox. Changing these fluids annually is a great preventative measure.
Breathe Easy: Air Filter Maintenance
Your air filter is the lung of your ATV. For off-roaders, it gets dirty fast. After every dusty ride, pull the filter out from under the seat. If it’s a foam filter, wash it with filter cleaner and hot, soapy water, let it dry completely, and then re-oil it with proper foam filter oil. If it’s a paper element, tap it out gently or replace it if it’s too clogged.
Common Problems with the 2015 Can-Am Outlander 800 (And How to Fix Them)
Even the best machines have their quirks. Knowing the most common problems with 2015 can am outlander 800 models can help you quickly diagnose an issue on the trail or in the garage. This is how to 2015 can am outlander 800 troubleshooting.
Problem #1: Overheating
Symptoms: Temperature light flashing, engine sputtering, coolant boiling over.
The Culprit: Most often, it’s a radiator caked in mud. The fan can’t pull air through it. Other causes include a faulty cooling fan, a bad thermostat, or a failed water pump.
The Fix: Start with the simple stuff. Let the machine cool down completely. Get a pressure washer or strong hose and spray the radiator from the backside forward. This pushes the mud out the way it came in. If it still overheats, check if the fan kicks on. If not, you may have a bad fan motor, relay, or sensor—time to break out the multimeter or head to a mechanic.
Problem #2: Electrical Gremlins & Limp Mode
Symptoms: ATV suddenly loses power and won’t go over 10-15 mph, check engine light is on, display flashes codes.
The Culprit: Limp mode is a safety feature to prevent engine damage. It can be triggered by dozens of things, from a faulty throttle position sensor (TPS) to a bad connection at the battery or a failing voltage regulator/stator.
The Fix: First, ensure your battery terminals are clean and tight. A loose connection can cause voltage drops that throw the computer into a frenzy. Next, inspect the wiring harness for any obvious damage, especially around the engine and handlebars. If the problem persists, you’ll need to read the fault codes, which often points you directly to the faulty sensor. A failing stator is another common issue; a symptom is a battery that won’t stay charged.
Problem #3: Drivetrain Noises
Symptoms: Clunking, grinding, or whining noises, especially when turning or accelerating.
The Culprit: Universal joints (U-joints) on the driveshafts are a frequent wear item. Wheel bearings and the driveshaft carrier bearing are other common sources of noise and vibration.
The Fix: Safely jack up the machine and support it on jack stands. Grab each wheel at the top and bottom and try to wiggle it; any play indicates a bad wheel bearing. Grab the driveshafts and try to twist and move them; any clunking or excessive movement points to worn U-joints. Replacing these parts is a common DIY job for a careful mechanic with the right tools, like a press or a good vise.
Off-Road Setup: Essential 2015 Can Am Outlander 800 Tips
The stock Outlander is great, but a few key upgrades can transform it into a trail-devouring monster tailored to your riding style. Here are a few practical 2015 can am outlander 800 tips for making it your own.
Tires: The Single Best Upgrade
Factory tires are a compromise. Swapping them out is the fastest way to improve performance. For general trail riding, look at a 6-ply all-terrain tire like the Maxxis Bighorn 2.0. If you live in the mud, something aggressive like the ITP Cryptid is a better choice. Be mindful that going too big (over 27″) can put extra strain on your drivetrain.
Armor Up: Skid Plates & Bumpers
The plastic belly pan on your Outlander is fine for light duty, but one sharp rock can ruin your day. A full set of aluminum or UHMW (Ultra-High-Molecular-Weight polyethylene) skid plates is a wise investment. They protect your engine, differentials, and A-arms from costly damage. A heavy-duty front bumper also protects your radiator and plastics while providing a solid mounting point for lights.
A Guide to Sustainable & Eco-Friendly Riding
Being a true off-roader means respecting the environment we love to play in. A sustainable 2015 can am outlander 800 is one that’s maintained well and ridden responsibly. Adopting some eco-friendly 2015 can am outlander 800 practices ensures the trails stay open for everyone.
Tread Lightly
The number one rule is to stay on designated trails. Riding through sensitive areas can cause erosion and damage local ecosystems. Avoid spinning your tires unnecessarily, as it tears up the trail surface. Use a winch for recovery instead of trying to “power through” an obstacle that’s beyond your machine’s traction.
Proper Fluid Disposal
When you change your oil, coolant, or differential fluids, never dump them on the ground or down a drain. Collect them in a sealed container and take them to your local auto parts store or municipal recycling center. Most accept used fluids for free.
Efficiency Through Maintenance
A well-maintained ATV is a more efficient one. Keeping your air filter clean, using the correct engine oil, and ensuring your tires are properly inflated all contribute to better fuel economy and lower emissions. It’s good for your wallet and the environment.
