How to Change the Coolant on a 2013 Husqvarna TE449

Routine coolant changes are essential for maintaining your 2013 Husqvarna TE449's performance and longevity. This model uses a liquid-cooled, high-performance engine with dual radiators, and proper maintenance can prevent overheating and internal wear. Below is a step-by-step, MotoSport-exclusive guide for a safe and effective coolant change, tailored for the TE449.

What You'll Need

• Fresh coolant (ensure compatibility with aluminum radiators)
• Basic hand tools: sockets/wrenches, flathead screwdriver
• Drain pan
• Clean rags
• Funnel
• Distilled water (for flushing, optional but recommended)
• Gloves and safety glasses

Special Note for the 2013 Husqvarna TE449 Owner

• This bike features a high-compression, off-road-focused engine designed for aggressive riding. Using high-quality coolant is crucial for thermal management, especially during demanding rides or racing conditions.
• The radiator cap and drain screw configuration may differ from some other models–always reference your specific components during service to avoid confusion.

Step-by-Step Coolant Change Guide

1. Ensure Engine is Cool
   Always perform cooling system maintenance on a completely cold engine to avoid burns or pressure spray when opening the radiator cap.
2. Stabilize the Bike
   Position the TE449 upright, either on a center stand or a secure lift, for easy access to the drain and radiator.
3. Locate the Coolant Drain Screw
   On the right-hand (R.H.) side of the cylinder, place a drain pan under the coolant drain screw. Remove this screw first to start draining.
4. Slowly Remove the Radiator Cap
   After loosening the drain screw, open the left-hand (L.H.) radiator cap slowly, allowing air in and ensuring coolant flows out smoothly without splashing.
5. Flush the System (Recommended)
   For a more thorough coolant change, fill the radiator with distilled water and temporarily reinstall the cap and drain screw. Start the bike and run briefly (watch the temperature and DON'T let it overheat)–then shut off, let cool, and repeat the drain process. Skip flushing if you are only swapping coolant and the existing fluid is clean.
6. Reinstall Drain Screw
   Check the drain screw O-ring for wear and replace if needed. Reinstall and tighten the drain screw after all old coolant has drained or after your flush is complete.
7. Add New Coolant
   Using a funnel, carefully pour new coolant into the left radiator filler neck. Pour slowly to prevent air pockets. Fill until the coolant is roughly 10 mm above the radiator cells with the bike perfectly vertical and engine cold.
8. Bleed the System
   Gently squeeze coolant hoses to help release air bubbles. Reinstall the radiator cap once filled.
9. Run & Recheck
   Start the engine and let it idle until it reaches normal operating temperature. Shut off and let it cool. Check the level again–add more coolant if necessary, as trapped air may cause a drop.
10. Final Level Check
    With the bike cold and upright, top off the radiator as needed. The level should be about 10 mm above the radiator cells. Confirm reservoir level if equipped.

Important Tips for TE449 Coolant Maintenance

• Never use plain water or automotive coolant with silicates–these can damage off-road motorcycle cooling systems.
• Regularly inspect for leaks around hoses, cap, and water pump after service.
• Check the engine temperature gauge (if equipped) during your next ride for signs of overheating, and top off as required after your first heat cycle.
• Husqvarna recommends using coolant compatible with aluminum components to prevent corrosion and internal scaling.

Routine coolant changes will keep your 2013 TE449 running crisp on trail or track. For genuine replacement parts, radiators, and maintenance supplies, MotoSport offers an extensive selection tailored to your Husqvarna.
