The Arctic Cat Prowler 650 was a popular side-by-side, offering a blend of utility and recreational performance. However, like any machine, it wasn’t without its quirks. Owners have reported a range of issues over the years, from minor annoyances to more significant mechanical headaches. Understanding these common problems can help you troubleshoot issues, perform preventative maintenance, and ultimately keep your Prowler 650 running smoothly for years to come.

What's Going On With My Prowler? Common Issues and How to Tackle Them

Let's dive into the most frequently reported problems with the Arctic Cat Prowler 650, along with potential solutions and preventative measures.

1. Carburetor Conundrums: The Starting and Running Blues

The Prowler 650, being a carbureted machine, is susceptible to carburetor-related problems. These can manifest as difficulty starting, rough idling, poor performance, and even stalling.

  • The Culprit: Dirt and debris are the primary culprits. Fuel breaks down over time, leaving behind varnish that can clog jets and passages. Ethanol-blended fuel can also contribute to moisture buildup and corrosion within the carburetor.
  • The Fix: A thorough carburetor cleaning is often the first step. Disassemble the carburetor, soak the components in carburetor cleaner, and use compressed air to clear all passages. Pay special attention to the jets, pilot screw, and float needle valve. Inspect the fuel lines and fuel filter for any signs of degradation or blockage and replace them as needed.
  • Prevention is Key: Use a fuel stabilizer in your fuel tank, especially during periods of storage. Consider using non-ethanol fuel if available. Regularly inspect and clean the fuel filter.

2. Electrical Gremlins: Where Did My Power Go?

Electrical issues can be frustrating, often presenting as intermittent problems that are difficult to diagnose.

  • The Usual Suspects:
    • Battery: A weak or failing battery is a common cause of starting problems and can also affect the performance of other electrical components.
    • Stator: The stator is responsible for charging the battery. A faulty stator can lead to a dead battery and prevent the Prowler from running.
    • Voltage Regulator/Rectifier: This component regulates the voltage output to prevent overcharging the battery. A failing regulator/rectifier can damage the battery and other electrical components.
    • Wiring Harness: Damaged or corroded wiring can cause shorts, open circuits, and intermittent electrical problems.
    • Ignition Switch: A faulty ignition switch can prevent the engine from starting or cause it to stall.
  • Troubleshooting Steps:
    1. Battery Check: Have the battery load-tested to determine its health.
    2. Charging System Test: Use a multimeter to check the stator output and the voltage regulator/rectifier output. Consult your service manual for the correct voltage readings.
    3. Wiring Inspection: Carefully inspect the wiring harness for any signs of damage, corrosion, or loose connections. Pay close attention to areas where the wiring is exposed to the elements or subject to vibration. Use dielectric grease on all electrical connections to prevent corrosion.
    4. Fuse Check: Inspect all fuses for breaks. Replace any blown fuses with the correct amperage rating.
  • Pro Tip: A good service manual with a wiring diagram is invaluable for diagnosing electrical problems.

3. Overheating Woes: Keeping Your Cool

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

  • Possible Causes:
    • Low Coolant Level: Check the coolant level in the radiator and overflow tank.
    • Radiator Blockage: Mud, debris, and insects can clog the radiator fins, reducing its cooling efficiency.
    • Faulty Thermostat: A stuck-closed thermostat can prevent coolant from circulating through the engine.
    • Water Pump Failure: A failing water pump will not circulate coolant effectively.
    • Head Gasket Leak: A blown head gasket can allow combustion gases to enter the cooling system, causing overheating.
  • Troubleshooting and Solutions:
    1. Check Coolant Level: Top off the coolant level with the correct type of coolant.
    2. Clean Radiator: Use a garden hose to rinse the radiator fins from the inside out. A fin comb can help straighten bent fins.
    3. Thermostat Test: Remove the thermostat and test it in a pot of hot water. The thermostat should open at the specified temperature.
    4. Water Pump Inspection: Check the water pump for leaks or unusual noises. Replace the water pump if necessary.
    5. Head Gasket Check: Look for signs of coolant in the oil or oil in the coolant. A compression test can also help diagnose a head gasket leak.
  • Preventative Measures: Regularly check the coolant level and inspect the radiator for cleanliness. Consider using a coolant additive to improve cooling efficiency.

4. Suspension Sensations: Ride Quality Concerns

A comfortable ride is essential, and suspension problems can quickly detract from the Prowler 650's usability.

  • Common Complaints:
    • Rough Ride: This can be caused by worn shocks, stiff springs, or incorrect tire pressure.
    • Excessive Body Roll: This is often a sign of worn sway bar bushings or weak shocks.
    • Squeaking or Clunking Noises: These noises can indicate worn bushings, ball joints, or tie rod ends.
  • Diagnostic and Repair Tips:
    • Shock Inspection: Check the shocks for leaks, damage, or excessive wear. Replace worn shocks with new ones or consider upgrading to aftermarket shocks for improved performance.
    • Spring Inspection: Check the springs for cracks or sagging. Replace worn springs with new ones.
    • Bushing Inspection: Inspect all suspension bushings for wear or damage. Replace worn bushings with polyurethane bushings for increased durability.
    • Ball Joint and Tie Rod End Inspection: Check the ball joints and tie rod ends for play. Replace worn ball joints and tie rod ends.
    • Tire Pressure Adjustment: Ensure that the tire pressure is set to the recommended level.
  • Maintenance Matters: Regularly lubricate all suspension components to prevent wear and tear.

5. Transmission Troubles: Shifting and Gear Issues

The transmission is a critical component, and any problems here can render the Prowler unusable.

  • Typical Problems:
    • Difficulty Shifting: This can be caused by a worn shift cable, a faulty shift linkage, or low transmission fluid.
    • Slipping Gears: This is often a sign of worn clutch plates or low transmission fluid.
    • Unusual Noises: Grinding or whining noises can indicate worn gears or bearings.
  • Troubleshooting Tactics:
    1. Shift Cable Adjustment: Adjust the shift cable according to the service manual.
    2. Shift Linkage Inspection: Inspect the shift linkage for wear or damage. Replace worn components.
    3. Transmission Fluid Check: Check the transmission fluid level and condition. Top off the fluid level with the correct type of fluid. If the fluid is dirty or contaminated, drain and refill the transmission.
    4. Clutch Inspection: If the transmission is slipping, inspect the clutch plates for wear. Replace worn clutch plates.
    5. Internal Inspection: If the transmission is making unusual noises, it may be necessary to disassemble the transmission for inspection. This is best left to a qualified mechanic.
  • Preventative Care: Change the transmission fluid regularly according to the manufacturer's recommendations. Avoid aggressive shifting and excessive wheel spin.
