How to Change the Coolant in a 2006 Husqvarna TE450
Changing the coolant on your 2006 Husqvarna TE450 is an essential maintenance task to ensure optimal engine performance and longevity. The TE450 features a high-performance four-stroke engine that can be sensitive to overheating if the cooling system isn’t serviced regularly. Follow this exclusive MotoSport guide for a hassle-free coolant change.
Tools – Supplies Needed
- Fresh motorcycle coolant (silicate-free, pre-mixed or mixed with distilled water)
- Drain pan or buckets
- Socket or T-handle wrench for drain bolt removal
- Funnel or long-neck bottle
- Gloves and basic rags
- Distilled water (for flushing), if desired
Step 1: Preparation
- Ensure the engine is cool before working on the cooling system to prevent burns.
- Secure the TE450 level, using a stand to keep the bike stable and upright for accurate draining and filling.
- Remove the radiator cap slowly to release any pressure.
Step 2: Drain the Old Coolant
- Locate the water pump cover on the lower right side of the engine.
- Place the drain pan directly under the water pump area.
- Remove the coolant drain bolt (usually at the lowest point of the water pump cover) using your wrench.
- Allow all coolant to drain out completely. You can gently tilt the bike or squeeze the radiator hoses to help remove any trapped fluid.
Step 3: Flush the System (Recommended)
- Reinstall the drain bolt temporarily, then fill the system with distilled water.
- Start the bike and let it run for a minute to circulate the water (do not let it get hot).
- Shut off the engine, let it cool, then remove the drain bolt to drain the flush water. Repeat if coolant was very dirty.
Step 4: Reinstall Drain Bolt – Fill with New Coolant
- Install a new washer on the drain bolt if available. Tighten the drain bolt securely.
- Using a funnel, slowly fill the radiator with the recommended coolant to the top of the filler neck.
- Check if your TE450 has a coolant overflow reservoir, and fill it to the upper line as well (refer to your owner's manual for specific levels).
Step 5: Burp the Radiator – Remove Air Bubbles
- With the radiator cap still off, start the motor and let it idle. Gently rock the bike or blip the throttle to free any trapped air in the system.
- Watch for the fluid level to drop as air escapes; add coolant as needed until the level stabilizes at the filler neck.
- Reinstall the radiator cap once no more air bubbles surface.
Step 6: Check Levels – Final Inspection
- Run the bike for a few minutes and monitor for leaks around the drain bolt, water pump cover, and hoses.
- After the engine cools, re-check the fluid level in both the radiator and any reservoir, topping off if necessary.
- Properly dispose of any old coolant according to local regulations.
Important Notes for the 2006 Husqvarna TE450 Owner
- This model’s robust 4-stroke engine benefits from a high-quality coolant to minimize corrosion and scale buildup in the aluminum radiator and engine passages.
- Always use distilled water for mixing coolant, not tap water, to prevent deposits and potential overheating issues.
- Inspect radiator hoses and clamps for wear or leaks – 2006-TE models may develop cracks or loosen over time. Consider replacing old hoses with silicone upgrades for improved durability.
- After any hard ride, check your coolant level when cool, especially if riding in hot climates or tight trails.
Regular coolant service is a must for keeping your TE450 running cool and reliable, giving you the confidence to push harder on every ride.
