The Can-Am Outlander 570 is a popular mid-size ATV known for reliability and strong performance. Regular spark plug maintenance helps ensure smooth idling, steady acceleration, and fuel efficiency. This guide provides a practical, step-by-step approach to changing the spark plug on the Can-Am Outlander 570, covering tools, safety, removal, inspection, gap setting, installation, and post-change checks.
Tools And Safety
Before starting, gather the right tools and observe safety precautions. Essential items include a spark plug socket, a ratchet wrench, a torque wrench, a flat-blade screwdriver or pry tool, a gap feeler gauge, anti-seize compound, dielectric grease, and a spark plug boot puller if available. Have a clean work area and a spark-free environment. Always ensure the engine is cool to avoid burns and wear gloves and eye protection. Disconnect the negative battery terminal to prevent any accidental starting or electrical shorts during the procedure.
Identify The Correct Spark Plug
Check the owner’s manual or the service manual for the exact spark plug specification for the 570 Outlander. Many Can-Am models use a specific NGK or Denso plug with a defined heat range and thread size. If you cannot locate the exact part number, remove the existing plug as a reference and replace with the same type and thread size. Confirm the recommended gap, which is typically in the range of a few thousandths of an inch, but always verify the precise specification for your model before adjusting.
Preparation For Removal
Prepare the ATV for access to the spark plug. Remove any protective body panels or covers that block access to the spark plug location. Clean the area around the spark plug to prevent dirt or debris from entering the combustion chamber when the plug is removed. Keep a clean workspace and have a rag ready to wipe off any exposed threads or plugs after removal.
Removing The Spark Plug
Using a spark plug socket and a ratchet, carefully loosen and remove the spark plug. Turn counterclockwise to loosen, then remove by hand to minimize cross-threading. Inspect the plug threads and the condition of the seal and boot. If the plug is fouled, oily, or damaged, replace with a new plug of the correct type. If the plug shows normal wear with a light tan color, it may indicate proper combustion, but consider replacement if it has reached the end of its service life as recommended in the manual.
Gapping And Preparation Of The New Spark Plug
Estimate the gap on the new spark plug using a feeler gauge. The gap specification is model-specific; consult the owner’s manual. Use a precise gauge to set the gap within the prescribed range. Apply a small amount of anti-seize compound to the threads if instructed by the manufacturer, and lightly coat the spark plug electrode and threads with dielectric grease to ease future removal and improve sealing. Do not apply excessive anti-seize or grease, which can affect heat transfer or cause fouling.
Installation And Torque
Thread the new spark plug by hand to avoid cross-threading, then tighten to the manufacturer’s recommended torque. For most small-displacement ATVs, the torque is typically in the range of 9 to 15 Nm, but confirm the exact specification for the Outlander 570. After reaching the recommended torque, snug slightly for a proper seal if a torque wrench is unavailable, but avoid over-tightening. Reconnect the spark plug boot firmly, ensuring a good seal to prevent arcing or misfires.
Reassembly And Testing
Reinstall any panels or covers removed for access. Reconnect the negative battery cable. Start the ATV and let it run at idle briefly to verify a stable idle and smooth acceleration. Listen for any misfires, rough running, or unusual exhaust sounds. If the engine runs inconsistently or shows signs of misfire, recheck the plug seating, gap, and boot connection. If problems persist, consider inspecting ignition coils and wiring for faults or consulting a technician.
Maintenance Tips And Best Practices
Routine checks help extend spark plug life and performance. Replace the plug at intervals recommended by Can-Am or sooner if symptoms appear, such as rough idling, hard starting, reduced power, or increased fuel consumption. Use high-quality plugs from reputable brands, and keep the spark plug boot and connector clean and dry. Maintain proper air and fuel system health, including clean air filters and correct fuel mixture, as poor air/fuel ratios can foul plugs quickly. Store the vehicle in a dry environment to reduce corrosion on terminals and threads.
Common Problems And Quick Fixes
Symptoms and probable causes include:
- Hard starting or no start: check spark plug condition, gap, and boot connection; inspect ignition coil health.
- Rough idle or misfire: inspect plug color; a completely fouled plug indicates rich fuel mix or oil intrusion; service spark plug, check carburetor or EFI settings.
- Loss of power: verify the plug is properly gapped and seated; examine wiring harness for damage; ensure ignition timing is correct if applicable.
- Frequent fouling: verify air filter cleanliness, fuel quality, and spark plug heat range; avoid short trips that foul plugs, and consider upgrading to a more suitable heat range if conditions require it.
When To Change Spark Plugs On A Can-Am Outlander 570
Change the spark plug as part of regular preventive maintenance per Can-Am guidelines or sooner if you notice poor performance. In conditions with dusty environments, short trips, or frequent starts, plugs may require more frequent inspection and replacement. Always replace with the recommended type and gap to maintain optimal combustion and engine reliability.
Troubleshooting Quick Reference
If the spark plug seems difficult to remove or the boot is stubborn, apply a small amount of electrical contact cleaner or dry lubricant around the boot edge and work gently. Cross-threading can damage the cylinder head and require more extensive repairs. If you are unsure about the plug type or torque specifications, consult the official Can-Am service manual or a certified technician for model-specific guidance.
