Routine coolant changes are vital to keeping your 2007 Husqvarna TE450 running cool and performing at its peak. The cooling system on this model is robust but requires periodic maintenance due to the heat and stress generated by the high-revving four-stroke engine. Follow this exclusive MotoSport.com step-by-step guide to safely change your TE450's coolant and keep your bike ready for the track or trail.
What You Will Need
- Fresh coolant compatible with aluminum radiators (avoid silicate-based formulas)
- Socket or wrench set
- Drain pan or vessel
- Funnel
- Clean shop rags
- Safety gear – gloves and eye protection
Step-by-Step Coolant Change Instructions
- Let the engine cool completely. Never attempt to open the radiator cap with a hot engine as scalding coolant can spray out under pressure.
- Locate the coolant drain screw. Place your bike on a stand for stability. On the 2007 TE450, the coolant drain screw is found on the right-hand side of the cylinder. Position your drain pan directly underneath this area.
- Remove the drain screw. Unscrew the coolant drain bolt and allow the old coolant to flow fully into your vessel. For a more thorough drain, you can gently tip the motorcycle to the right side.
- Remove the radiator cap slowly. Crack the cap open gently to release any remaining pressure and allow extra coolant to drain.
- Flush the system if needed. Fill the radiator with distilled water, reinstall the drain bolt, run the engine briefly, then repeat the draining procedure. This helps remove any residual contaminants or old coolant. Skip if coolant is clean and recent.
- Inspect hoses & clamps. Carefully check all coolant hoses for any signs of swelling, cracking, or hardening. The TE450 hoses are prone to deterioration from repeated heat cycles. Replace any damaged hoses and ensure all clamps are tight and secure to prevent leaks.
- Reinstall the drain screw. Ensure it is snug, but do not overtighten to avoid damaging threads.
- Refill the radiator. Using a funnel, slowly pour your new coolant into the radiator until it reaches the proper fill level. Do not overfill.
- Bleed trapped air. Start the engine and let it idle with the radiator cap off until the coolant cycles and any air bubbles escape. Top off as needed, then securely reinstall the cap.
- Check connections and final levels. After engine cools from a short ride, double-check hose connections, inspect for any leaks, and verify coolant is at correct level.
Important TE450 Model Notes
- This bike's high-performance, liquid-cooled four-stroke engine is sensitive to overheating. Never neglect routine coolant inspection—leakage or degradation can result in engine seizure.
- The radiator cap and drain bolt are directly accessible, but always wait until the engine is fully cold before servicing.
- Avoid letting coolant contact painted or varnished surfaces as it can damage finishes—if spills occur, rinse thoroughly with water.
- The 2007 TE450 may have a cooling fan that can activate even when the ignition is off—keep fingers clear around radiator assemblies when working.
Maintenance Tips
- Change coolant every 1-2 years or any time you notice discoloration or contamination.
- Periodically check all coolant hoses and replace at the first sign of wear.
- If you regularly race or ride in extreme conditions, increase inspection and change intervals accordingly.
Your 2007 Husqvarna TE450 deserves premium maintenance. Keep your cooling system in optimal condition for maximum ride time and confidence on every journey.
