The Can Am Outlander 570 relies on a reliable spark plug to deliver smooth starts, efficient combustion, and consistent performance across trails and work tasks. This guide covers the right spark plug types, gap specifications, replacement intervals, and practical steps to diagnose and replace the plug on the Outlander 570. Readers will learn how to choose the correct brand, ensure proper gap, and avoid common mistakes that can affect cold starts and acceleration.
Spark Plug Basics For The Outlander 570
The Outlander 570 uses a single-cylinder four-stroke engine that benefits from a high-quality spark plug designed for ATV use. A good plug delivers a strong, consistent spark at all operating temperatures, helps achieve clean combustion, and minimizes fouling. Brands commonly recommended by Can Am enthusiasts include NGK and Denso, both offering OEM-equivalent and performance variants. Compatibility depends on the exact model year and regional specifications, so checking the owners manual or OEM parts catalog is essential before purchasing.
Replacement Interval And Indicators
Typical replacement intervals for the Outlander 570 can range from 6,000 to 10,000 miles depending on usage, fuel quality, and climate. In dusty or high-load environments, more frequent changes may be necessary. Key indicators that the spark plug needs replacement include hard starting, rough idle, misfires under load, reduced fuel efficiency, and loss of power during acceleration. If the engine shows any of these symptoms, inspect the plug for fouling, glazing, or worn electrodes and replace as needed.
Choosing The Right Spark Plug
The most important consideration is selecting a plug that matches the Outlander’s ignition system and operating temperature range. For many Can Am owners, the standard NGK CR8E or RNK series plugs are reliable choices, along with equivalent Denso models. When selecting a plug, consider:
- Heat range: A plug that is too hot can pre-ignite and cause engine damage; too cold can foul easily in rich conditions. Use the heat range recommended by Can Am for your specific model year.
- Electrode design: Copper cores heat quickly and dissipate heat well, while iridium and platinum plugs offer longer life but at a higher cost. For daily trail riding and occasional work tasks, iridium or platinum variants are common upgrades.
- Thread size and reach: Ensure correct thread diameter and reach to avoid cross-threading or incomplete sealing.
Gap Setting And Install Process
Correct spark plug gap is crucial for optimal ignition. The typical gap for the Outlander 570 ranges around 0.028 to 0.030 inches (0.70–0.76 mm), but always verify with the specific model year in the service manual. To set the gap, use a calibrated feeler gauge and gently adjust the center electrode without bending it. When installing, thread by hand to avoid cross-threading, then tighten to the manufacturer’s torque specification, usually around 12–15 Nm (9–11 ft-lb) for many ATV plugs. Apply a light anti-seize compound on the threads if recommended by the OEM, and reinstall the spark plug cap securely.
Symptoms Of A Failing Spark Plug
Identifying worn or fouled plugs early can prevent more serious engine issues. Common symptoms include:
- Hard starting: Strong cranking without consistent ignition.
- Rough idle or misfire: The engine lurches at idle or misfires under load.
- Loss of power: Reduced acceleration and climbing capability.
- Increased fuel consumption: Noticeable drop in efficiency.
- Visible fouling: Black, sooty deposits or oily residue on the plug tip.
Maintenance Tips To Extend Spark Plug Life
Regular preventive maintenance helps extend spark plug life and engine reliability. Consider these practices:
- Use clean, high-quality fuel: Prevents deposits that foul the plug.
- Keep air filters clean: Reduces dirt ingestion that can contaminate the combustion chamber.
- Perform regular idle and temperature checks: Maintain proper engine heat and avoid rich-running conditions.
- Inspect ignition components: Wires and coils should be intact and free of cracks or corrosion.
- Use sealed spark plug boots: Ensure a tight seal against moisture and vibration.
How To Change The Spark Plug On The Can Am Outlander 570
Changing the spark plug is a straightforward maintenance task that can be performed with basic hand tools. Steps include:
- Remove the seat or access panel to reach the spark plug area according to the model year.
- Disconnect the ignition coil boot and gently remove the old plug with a suitable deep-well socket.
- Inspect the porcelain and the tip for signs of wear or fouling; note the gap.
- Install the new plug with a light coating of anti-seize if recommended, and tighten to torque specification.
- Reconnect the boot securely and reassemble any panels.
Common Mistakes To Avoid
Avoid these pitfalls to ensure reliable ignition and long plug life:
- Over-tightening: Can damage threads and seat.
- Incorrect gap: Leads to misfires and poor performance.
- Using the wrong heat range: Causes fouling or pre-ignition.
- Forgetting to check ignition components: Worn wires or coils can mimic plug problems.
Frequently Asked Questions
Q: Can I use automotive spark plugs in the Outlander 570?
A: Automotive plugs are generally not recommended due to different heat ranges and construction; use ATV-specific or OEM-replacement plugs designed for motorcycle/ATV ignition systems.
Q: How do I know if the spark plug gap is correct?
A: Use a calibrated gap tool, compare with the specific model’s recommended gap in the owner’s manual, and adjust if needed.
Q: How often should I replace the spark plug?
A: Replacement intervals vary by usage, but a baseline is every 6,000–10,000 miles or as symptoms appear, with more frequent changes in harsh conditions.
