The Can-Am Outlander 650 XT is a formidable ATV, known for its power, versatility, and impressive features. However, like any complex machine, it's not immune to issues. Understanding the potential problems you might encounter with your Outlander 650 XT allows you to be proactive in maintenance, troubleshoot effectively, and ultimately maximize your enjoyment of this capable off-road vehicle.

Common Issues and What You Can Do About Them

Let's dive into some of the most frequent problems reported by Can-Am Outlander 650 XT owners and explore potential solutions. Remember, safety first! Always consult your owner's manual and consider professional assistance if you're not comfortable performing repairs yourself.

1. The Dreaded "Check Engine" Light

That little orange engine icon illuminating on your dashboard can induce instant anxiety. The "Check Engine" light is a broad indicator, meaning various issues could trigger it.

  • Possible Causes:
    • Loose Gas Cap: Surprisingly common! A poorly sealed gas cap can cause evaporative emissions system issues.
    • Faulty Sensors: O2 sensors, throttle position sensors (TPS), and crankshaft position sensors are all susceptible to failure.
    • Exhaust Leaks: Cracks or loose connections in the exhaust system can disrupt the engine's air-fuel mixture.
    • Fuel Injector Problems: Clogged or malfunctioning fuel injectors can lead to poor performance and misfires.
    • Engine Misfires: Caused by faulty spark plugs, ignition coils, or fuel delivery issues.
  • Troubleshooting Steps:
    • Check the Gas Cap: Tighten or replace it if it's damaged.
    • OBD-II Scanner: Invest in an OBD-II scanner (or borrow one from a friend/auto parts store). This device plugs into your ATV's diagnostic port and reads the error codes that triggered the "Check Engine" light. Write down the codes!
    • Consult the Service Manual: Your service manual will provide detailed information about each error code and potential solutions.
    • Inspect Wiring and Connections: Look for loose, corroded, or damaged wires and connectors around the engine and related components.
    • Professional Diagnosis: If you're unsure about the cause or how to fix it, take your ATV to a qualified mechanic.

2. Overheating: Keep Your Cool

An overheating engine can cause serious damage. It's crucial to address overheating issues promptly.

  • Possible Causes:
    • Low Coolant Level: The most obvious culprit.
    • Clogged Radiator: Mud, debris, and even insects can block airflow through the radiator.
    • Faulty Thermostat: A stuck or malfunctioning thermostat can prevent coolant from circulating properly.
    • Water Pump Failure: The water pump circulates coolant throughout the engine. If it fails, the engine will overheat quickly.
    • Air Lock in the Cooling System: Air bubbles can prevent proper coolant circulation.
  • Troubleshooting Steps:
    • Check Coolant Level: Ensure the coolant reservoir is filled to the proper level. Use the correct type of coolant specified in your owner's manual.
    • Inspect the Radiator: Clean the radiator fins thoroughly with a garden hose. Use a soft brush to remove stubborn debris.
    • Check the Thermostat: Remove the thermostat and test it in a pot of boiling water. It should open fully. Replace it if it doesn't.
    • Inspect the Water Pump: Look for leaks around the water pump. If the pump is making unusual noises or not circulating coolant, it may need to be replaced.
    • Bleed the Cooling System: Follow the procedure in your service manual to remove air bubbles from the cooling system.

3. Suspension Woes: A Rough Ride

The Outlander 650 XT's suspension is designed to provide a comfortable and controlled ride, but it can develop problems over time.

  • Possible Causes:
    • Worn Bushings: Bushings in the A-arms, sway bar links, and other suspension components can wear out, causing play and noise.
    • Damaged Shocks: Leaking shocks, bent shock shafts, or blown seals can compromise suspension performance.
    • Loose Suspension Components: Bolts and nuts can loosen over time, leading to instability.
    • Bent A-Arms: Impacts with rocks or other obstacles can bend A-arms, affecting alignment and handling.
  • Troubleshooting Steps:
    • Inspect Bushings: Check for excessive play or cracking in the bushings. Replace worn bushings as needed. Polyurethane bushings are often a more durable upgrade.
    • Inspect Shocks: Look for leaks or damage to the shock bodies and shafts. Consider rebuilding or replacing damaged shocks.
    • Tighten Suspension Components: Check and tighten all bolts and nuts in the suspension system to the proper torque specifications.
    • Inspect A-Arms: Visually inspect A-arms for bends or damage. Replace bent A-arms.

4. Electrical Gremlins: The Unseen Enemy

Electrical problems can be frustrating to diagnose and fix.

  • Possible Causes:
    • Dead Battery: A weak or dead battery is a common culprit.
    • Loose or Corroded Connections: Vibration and exposure to the elements can loosen or corrode electrical connections.
    • Faulty Wiring: Damaged or frayed wires can cause shorts or open circuits.
    • Blown Fuses: Overloads or short circuits can blow fuses.
    • Stator or Regulator/Rectifier Problems: These components are responsible for charging the battery.
  • Troubleshooting Steps:
    • Check the Battery: Test the battery voltage with a multimeter. A fully charged battery should read around 12.6 volts. Charge or replace the battery if necessary.
    • Inspect Connections: Clean and tighten all electrical connections, especially those at the battery terminals, starter, and ground points. Use dielectric grease to protect connections from corrosion.
    • Inspect Wiring: Look for damaged or frayed wires. Repair or replace damaged wiring.
    • Check Fuses: Check all fuses in the fuse box. Replace any blown fuses with the correct amperage rating.
    • Test the Stator and Regulator/Rectifier: Consult your service manual for instructions on how to test these components.

5. Brake Issues: Stop Right There!

Properly functioning brakes are essential for safety.

  • Possible Causes:
    • Worn Brake Pads: Brake pads wear down over time and need to be replaced.
    • Air in the Brake Lines: Air bubbles can compromise braking performance.
    • Leaking Brake Lines or Calipers: Leaks can reduce brake fluid pressure.
    • Damaged Brake Rotors: Warped or scored brake rotors can cause vibrations and reduced braking power.
  • Troubleshooting Steps:
    • Inspect Brake Pads: Check the thickness of the brake pads. Replace them if they are worn to the wear indicators.
    • Bleed the Brakes: Bleed the brake lines to remove air bubbles.
    • Inspect Brake Lines and Calipers: Look for leaks around the brake lines and calipers. Repair or replace leaking components.
    • Inspect Brake Rotors: Check the brake rotors for warping or scoring. Replace damaged rotors.

6. Fuel System Troubles: Starving for Power

Problems with the fuel system can lead to poor performance, stalling, and difficulty starting.

  • Possible Causes:
    • Clogged Fuel Filter: A clogged fuel filter restricts fuel flow to the engine.
    • Dirty Fuel Injectors: Dirty fuel injectors can spray fuel unevenly, leading to poor combustion.
    • Faulty Fuel Pump: A weak fuel pump may not deliver enough fuel to the engine.
    • Water in the Fuel: Water contamination can cause various fuel system problems.
  • Troubleshooting Steps:
    • Replace the Fuel Filter: Replace the fuel filter regularly, as recommended in your owner's manual.
    • Clean Fuel Injectors: Use a fuel injector cleaner additive or have the injectors professionally cleaned.
    • Test the Fuel Pump: Check the fuel pump pressure. A weak fuel pump may need to be replaced.
    • Drain the Fuel Tank: Drain the fuel tank and refill it with fresh fuel if you suspect water contamination.

Preventative Maintenance: An Ounce of Prevention...

Regular preventative maintenance is the best way to minimize problems with your Can-Am Outlander 650 XT. Here are some key maintenance tasks:

  • Regular Oil Changes: Change the engine oil and filter at the intervals recommended in your owner's manual.
  • Air Filter Cleaning/Replacement: Clean or replace the air filter regularly to ensure proper airflow to the engine.
  • Grease Fittings: Grease all grease fittings on the suspension and steering components to keep them lubricated.
  • Inspect and Adjust Brakes: Regularly inspect the brake pads and rotors and adjust the brakes as needed.
  • Check Tire Pressure: Maintain proper tire pressure for optimal handling and tire life.
  • Inspect and Tighten Fasteners: Regularly inspect and tighten all bolts and nuts on the ATV.
  • Store Properly: If you're not using your ATV for an extended period, store it properly to prevent damage. Use a fuel stabilizer, disconnect the battery, and cover the ATV to protect it from the elements.
