Why the 2021 Can-Am Outlander 450 is a Trail Favorite
Before we dive into the nuts and bolts, let’s appreciate what makes this ATV special. The Outlander 450 isn’t just another quad; it’s a platform built on Can-Am’s reputation for performance and reliability. This is a core part of understanding the benefits of the 2021 can am outlander 450.
At its heart is the dependable 38-hp single-cylinder Rotax engine. This isn’t some generic motor; Rotax has a legacy in everything from snowmobiles to aircraft. It provides smooth, predictable power that’s perfect for both technical trails and hauling gear.
Paired with a responsive CVT (Continuously Variable Transmission) and selectable 2WD/4WD, you get a machine that’s incredibly easy to handle. Add in the comfortable ergonomics and robust steel racks, and you have a versatile ATV that’s as happy on a hunting trip as it is doing chores.
The Pre-Ride Inspection: Your 10-Minute Safety Ritual
The single most important habit you can develop is the pre-ride inspection. It takes less than 10 minutes and can prevent a minor issue from becoming a major breakdown—or worse, a safety hazard. This is the foundation of any good 2021 can am outlander 450 care guide.
Think of it as a quick conversation with your machine. Here’s a simple checklist to follow every single time you head out.
Tires and Wheels
Your tires are your only connection to the ground. Give them the attention they deserve.
- Pressure Check: Use a quality low-pressure tire gauge. The recommended pressure is printed on the tire sidewall—typically around 5-7 PSI. Improper pressure leads to poor handling and premature wear.
- Visual Inspection: Look for any cuts, punctures, or embedded objects. Check the sidewalls for cracks.
- Lug Nuts: Give the wheels a quick wiggle. If there’s any play, grab a torque wrench and ensure your lug nuts are tightened to spec (check your owner’s manual).
Controls and Cables
Smooth operation is safe operation. Your controls need to be predictable and responsive.
- Throttle: Check for smooth operation. It should snap back cleanly when you release it. If it’s sticky, the cable may need lubrication or adjustment.
- Brakes: Squeeze the brake levers. They should feel firm, not spongy. A spongy feel often indicates air in the brake lines. Check the brake fluid reservoir level.
- Steering: Turn the handlebars from lock to lock. It should move freely without binding.
Fluids and Lights
Your ATV’s lifeblood. Low fluids can cause catastrophic damage in minutes.
- Engine Oil: With the ATV on level ground, pull the dipstick, wipe it clean, re-insert it fully, and pull it out again to check the level. It should be between the ‘add’ and ‘full’ marks.
- Coolant: Check the coolant level in the overflow reservoir. Never open the radiator cap when the engine is hot.
- Lights & Electrics: Turn the key on. Test your headlights (high and low beams), taillights, and brake lights. A quick test ensures you’re visible and can see the trail ahead.
Essential DIY Maintenance for Your 2021 Can-Am Outlander 450
Ready to move beyond the basics? These are the core maintenance tasks every owner should know how to do on a 2021 can am outlander 450. You’ll need a basic set of metric sockets, wrenches, a drain pan, and some shop towels. Always consult your owner’s manual for specific fluid types and capacities.
Engine Oil & Filter Change
This is the most frequent and vital maintenance task. Fresh oil keeps your Rotax engine lubricated, cool, and clean.
- Warm It Up: Run the engine for 3-5 minutes. This helps the oil drain faster and suspends contaminants.
- Drain the Old Oil: Place a drain pan under the engine and remove the drain plug. Be careful, as the oil will be warm.
- Replace the Filter: While the oil drains, use an oil filter wrench to remove the old filter. Make sure the old rubber gasket comes off with it.
- Install the New Filter: Apply a thin layer of new oil to the gasket of the new filter. Screw it on by hand until it’s snug, then give it another quarter-turn with the wrench. Do not overtighten.
- Refill and Check: Re-install the drain plug (with a new sealing washer if required) and torque it to spec. Refill with the recommended oil (typically a 5W-40 synthetic blend). Start the engine for 30 seconds, shut it off, wait a minute, and re-check the level on the dipstick, topping off as needed.
Air Filter Service
An off-road engine breathes a lot of dust. A clean air filter is non-negotiable for engine health.
The airbox is usually located under the seat. Open it up and carefully remove the air filter. If it’s a foam filter, wash it with filter cleaner and warm, soapy water. Let it dry completely, then re-oil it with foam filter oil. If it’s a paper filter that is heavily soiled, it’s best to simply replace it. A clean filter is one of the best 2021 can am outlander 450 tips for performance.
Drivetrain and Differential Fluids
Your 4WD system relies on gear oil in the front and rear differentials. These fluids don’t need changing as often as engine oil, but they must be checked.
Locate the fill plugs on the front and rear differentials. With the ATV on level ground, remove the plug. The fluid level should be right at the bottom of the threads. If you need to top it off, use the specific gear oil recommended by Can-Am.
Troubleshooting Common Problems with the 2021 Can-Am Outlander 450
Even the most reliable machines can have off days. Knowing how to diagnose common problems with the 2021 can am outlander 450 can save you a tow from the trail. Here are a few frequent culprits and what to check.
Starting Issues: No Crank or Won’t Fire
You turn the key and… nothing. Don’t panic. Start with the simple stuff.
- The Battery: Is it charged? Are the terminals clean and tight? Corrosion can prevent a good connection. A simple voltmeter should read 12.6V or higher on a healthy, fully charged battery.
- Fuses: Check the main fuse, usually located near the battery. A blown fuse is an easy fix.
- Spark Plug: If the engine cranks but won’t start, the spark plug is a common suspect. A fouled or worn plug can’t deliver the spark needed for combustion.
- Fuel: It sounds obvious, but is there fresh fuel in the tank? Is the fuel valve on? Old fuel can also cause starting problems.
Overheating Concerns
If your temperature warning light comes on, stop immediately and let the engine cool down. Continuing to ride can cause severe engine damage.
First, check the coolant level in the overflow bottle. If it’s low, you may have a leak. Second, inspect the radiator. Is it caked with mud? A clogged radiator can’t dissipate heat. Hose it down (with low pressure) from the back towards the front to clear the fins.
Brake System Care
Brakes are a critical safety system. Regularly inspect the thickness of your brake pads through the calipers. You should see at least 1/8th of an inch of pad material. Also, keep an eye on the brake fluid level in the master cylinder reservoirs on the handlebars. If the fluid looks dark or murky, it’s time for a flush—a job you might want to leave to a pro if you’re not comfortable bleeding brake lines.
Best Practices for Long-Term Ownership and Sustainability
A true enthusiast knows that ownership goes beyond just riding. Following these 2021 can am outlander 450 best practices ensures your machine lasts and that you’re being a responsible member of the off-road community.
Proper Fluid Disposal
Being an eco-friendly 2021 can am outlander 450 owner means handling waste responsibly. Never dump used oil, coolant, or brake fluid on the ground or in the trash. Pour them into sealed containers and take them to your local auto parts store or municipal recycling center. Most places accept them for free.
Washing and Cleaning for Longevity
A clean ATV is more than just pretty—it’s a well-maintained ATV. Washing off mud and grime prevents corrosion and allows you to spot potential issues like oil leaks, loose bolts, or cracked parts you might otherwise miss. Pay special attention to cleaning the radiator and suspension components.
Smart Storage Solutions
If you’re storing your Outlander for more than a month, a little prep goes a long way. Add a fuel stabilizer to a full tank of gas and run the engine for a few minutes to circulate it. Connect the battery to a smart charger or battery tender to keep it healthy. Store the ATV in a dry, covered location if possible.
