Shop parts for a 2001 Husqvarna TC570 Dirt Bike.

Regularly changing the coolant in your 2001 Husqvarna TC570 is essential for maintaining optimal engine temperature, preventing corrosion, and ensuring peak performance on the track or trail. This model features a robust, liquid-cooled single-cylinder engine, so following the right steps will help protect your investment and keep your dirt bike running smooth.

What You Need

  • Fresh motorcycle coolant (do not use automotive coolant)
  • Distilled water (if coolant is concentrate)
  • Large drain pan
  • Socket set and screwdriver
  • Protective gloves and eyewear
  • Shop rags

Step-by-Step Coolant Change Instructions

  1. Ensure Safety and Prepare the Bike
    Let the engine cool completely before starting; hot coolant can cause burns. Position the bike upright or on a stand for stability. Remove any bodywork obstructing access to the radiator cap and water pump, if necessary.
  2. Drain the Old Coolant
    Place a drain pan under the water pump area. Remove the radiator cap first to allow air to flow, assisting drainage. Locate the coolant drain bolt (typically on or near the water pump cover for Husqvarna models) and remove it carefully. Allow all coolant to drain from the system.
  3. Flush (Optional but Recommended)
    If the old coolant looks dirty or contaminated, briefly flush with distilled water. Reinstall the drain bolt, fill with distilled water, run the engine for a minute, then drain again, ensuring all residues exit the system.
  4. Reinstall the Drain Bolt
    Inspect and, if needed, replace the sealing washer or O-ring to prevent leaks. Tighten the drain bolt securely but do not overtighten.
  5. Add Fresh Coolant
    Mix coolant according to manufacturer instructions, if using concentrate (typically 50 percent coolant and 50 percent distilled water). Pour coolant slowly into the radiator until it just reaches the base of the filler neck a slow pour minimizes air pockets.
  6. Remove Air Bubbles
    Squeeze the upper and lower radiator hoses by hand several times to release trapped air. Top off coolant if the level drops. Start the engine with the radiator cap off, gently rev the throttle a few times, and let the engine run briefly as more air bubbles escape. Turn off the engine, allow it to settle, and top off coolant as needed.
  7. Finish and Inspect
    Reinstall the radiator cap securely. Wipe away any spills and double-check all fasteners. Replace any bodywork you removed. Dispose of old coolant safely–never pour it down drains or onto the ground.

Important Notes for the 2001 Husqvarna TC570 Owner

  • This bike's high-performance 570cc powerplant can generate significant heat under aggressive riding. Always use high-quality, motorcycle-specific coolant for best protection.
  • Inspect cooling hoses and clamps during each coolant change–TC570 hoses can harden and become brittle over time.
  • The radiator's thin fins are susceptible to impact; clean gently and use a brush or compressed air for debris removal.
  • If you ride in harsh or muddy conditions, check the coolant more frequently, as contaminants can accelerate component wear.

Troubleshooting Tips

  • If you experience frequent overheating or notice coolant loss, inspect for leaks around hose joints, the water pump, or the head gasket.
  • A milky appearance in drained coolant could indicate oil mixing, suggesting a deeper engine issue.

Performing regular coolant changes is straightforward and critical for your bike’s longevity. With the right tools and attention to detail, your 2001 Husqvarna TC570 will stay cool and respond reliably, ride after ride.
