Maintaining the cooling system on your 2001 Husqvarna TE570 is crucial for optimum performance – this robust four-stroke dirt bike operates in demanding conditions, making a regular coolant change necessary to prevent overheating and internal damage. Here is a step-by-step guide to changing the coolant on your TE570, along with some key model-specific notes every owner should know:

What You Need:

  • Fresh motorcycle coolant (avoid automotive coolant; always choose a product compatible with aluminum engines)
  • Distilled water (if the coolant is concentrate)
  • Drain pan
  • Clean rags or paper towels
  • Socket wrench and screwdriver set
  • Protective gloves and safety glasses

Step 1: Preparation

  • Make sure your TE570 is on a stable stand with a cool engine. Never open the radiator cap when the engine is hot.
  • Remove the seat and any side panels if they restrict access to the radiator.

Step 2: Drain the Old Coolant

  • Locate the radiator cap and open it to relieve system pressure.
  • Find the coolant drain bolt, typically at the base of the water pump on the right side of the engine. Place your drain pan under this point.
  • Remove the drain bolt carefully. Let all coolant drain completely into the pan.
  • Inspect the drained fluid for signs of debris or oil, which could indicate internal issues.

Step 3: Flush the System (Recommended)

  • If your old coolant appeared rusty or contaminated, flush with distilled water. Pour distilled water into the radiator, reinstall the cap and drain bolt, run the engine briefly, then repeat the drain process.
  • Repeat flushing until the water runs clear. This helps prevent buildup and protects your cylinder head and water pump seals.

Step 4: Inspect and Replace Components

  • Check radiator hoses for cracks or hard spots and replace as needed.
  • Clean the radiator cap and check its seal. Replace if worn.
  • Inspect radiator fins for bends and carefully straighten if needed, as this improves cooling efficiency.

Step 5: Refill with New Coolant

  • Tighten the drain bolt securely (torque to factory spec if available).
  • If using concentrated coolant, mix it with distilled water as directed, typically 50/50.
  • Slowly fill the radiator with new coolant up to the base of the filler neck.
  • Gently rock the bike to release trapped air. Fill the overflow reservoir to the full mark.

Step 6: Bleed the Cooling System

  • Leave the radiator cap off, start the engine, and let it idle until it reaches operating temperature. Occasionally rev the throttle to help expel air bubbles.
  • Check the coolant level and refill as necessary until no more bubbles emerge and the level remains steady.
  • Install the radiator cap once the system is properly filled.

Step 7: Final Checks

  • Let the bike cool, then recheck coolant levels in both the radiator and overflow reservoir. Top off if necessary.
  • Check for leaks around the drain bolt, hoses, and radiator cap.
  • Reinstall the seat and side panels.

Important Notes for 2001 Husqvarna TE570 Owners

  • The 570 engine can run hot during slow or technical riding, so maintaining fresh coolant and a properly functioning radiator is vital.
  • The aluminum radiators on this model can be susceptible to damage; always check for bent or clogged fins and use soft water or premixed coolant designed for off-road motorcycles.
  • If you ride aggressively or in hot climates, consider upgrading to a high-pressure radiator cap for higher boiling resistance.
  • Always torque the drain and radiator bolts to spec to avoid stripping the engine case or damaging seals.
  • Watch for recurring coolant level drops; persistent loss may indicate internal engine issues unique to high performance, large displacement Husqvarna singles.

Performing a regular coolant change not only protects your investment but also helps you enjoy the full power and reliability of your 2001 Husqvarna TE570—on the trails or the track.
