Regular coolant replacement is essential to keep your 2002 Husqvarna TE570 running cool, prevent overheating, and avoid corrosion in the cooling system. This MotoSport.com guide walks you through the exact steps and specifics for this model so you can confidently perform your own coolant service.

What Makes the 2002 Husqvarna TE570 Unique?

  • High-performance engine: The TE570's large displacement engine produces significant heat. The cooling system relies on periodic checks and maintenance to function reliably, especially during off-road and enduro riding.
  • Fan safety: The cooling fan can activate even if the start switch is off. Always keep hands and tools clear of the fan when working around the radiators and hoses to prevent injury.
  • Sensitive hoses and clamps: Pay extra attention to the radiator hoses for signs of swelling, cracking, or hardening, especially given the age of these bikes. Replace any worn hoses and check clamp tightness for leaks.

Required Tools & Supplies

  • Phillips screwdriver or socket wrench
  • Drain pan or suitable container
  • Fresh motorcycle coolant (ethylene glycol-based, silicate-free)
  • Funnel
  • Gloves and rags

Step-By-Step Coolant Change Guide

  1. Prepare the Bike
    - Make sure the engine is cool before starting. Placing the bike on a stand helps with stability but slightly leaning it to the right side may improve draining.
  2. Locate & Remove the Coolant Drain Screw
    - Position your drain pan below the right-hand side of the cylinder, under the coolant drain screw (typically found near the water pump).
    - Remove the drain screw to begin draining the old coolant.
  3. Open the Radiator Cap SLOWLY
    - Open the right-hand radiator cap slowly to prevent sudden splashing or scalding.
    - Allow the old coolant to fully drain into the container.
    - You can lean the TE570 slightly to the right to help the system empty more effectively.
  4. Reinstall the Drain Screw
    - Once drained, replace and tighten the drain screw securely.
  5. Add Fresh Coolant
    - With a funnel, pour the recommended type and amount of coolant into the radiator up to the base of the filler neck.
  6. Eliminate Air Bubbles
    - Warm up the engine briefly with the radiator cap off to help purge any air from the system.
    - Watch for air bubbles as the engine runs.
    - After a few moments, shut off the engine and top off coolant as needed.
    - Install the radiator cap securely.
  7. Check Connections and Hoses
    - Inspect all hose connections for leaks. Check for aged or brittle hoses and replace them if needed.
    - Tighten hose clamps to factory spec.
  8. Final Check
    - After riding and once the bike is cool again, recheck the coolant level both at the radiator and in the overflow reservoir (if equipped). Top off as necessary.

Expert Tips for the TE570 Owner

  • Never remove the radiator cap when the engine is hot – pressurized coolant can cause burns.
  • The cooling fan may activate even when the ignition is off. Always verify the fan is not spinning before touching anything near the radiators.
  • Be vigilant about leaks on this model, as even small hose cracks or loose clamps can lead to loss of coolant and potential engine seizure.
  • The large-displacement engine excels at power but can run hot under hard use, so inspect your coolant condition and cooling system often.
  • Consider replacing the radiator cap periodically, especially if you notice coolant loss with no visible leaks. A cap with a built-in temperature gauge can help you monitor system health more easily.

Maintaining the cooling system on your 2002 Husqvarna TE570 is key to reliable performance on the trails or track. Stay ahead of potential issues by using these steps and keeping a close eye on coolant level, hose condition, and system pressure.
