How to Change the Coolant in a 2010 Husqvarna TE250
Shop parts for a 2010 Husqvarna TE250 Dirt Bike.
Regularly changing the coolant in your 2010 Husqvarna TE250 is essential for reliable performance and engine longevity. The TE250 features a liquid-cooled, four-stroke engine equipped with a dual-radiator system and an electric fan, both of which help manage heat in demanding riding conditions. Staying on top of your cooling system maintenance will keep your dirt bike running strong for seasons to come.
What You Need
- Fresh coolant compatible with aluminum engines (avoid anything with silicates)
- Drain pan or vessel
- Rags or towels
- Socket set or spanner appropriate for the drain bolt
- Funnel
- Distilled water (if flushing)
- Protective gloves and eye protection
Step-by-Step Coolant Change Guide
- Preparation: Ensure your bike is cool to avoid burns. Place the TE250 on a stand and make sure it's level to get a complete drain.
-
Drain the Radiator:
- Locate the coolant drain bolt (usually at the lower right side of the cylinder or on the water pump housing).
- Place a drain pan beneath it.
- Remove the radiator cap slowly to release pressure, then remove the drain bolt and allow coolant to fully drain.
-
Flush (Recommended):
- Refit the drain bolt and fill the radiator with distilled water.
- Run the engine briefly (1–2 minutes), then let it cool and drain again to remove old coolant residue.
- Inspect Hoses & Connections: Look for cracks or wear in the radiator hoses, and check all hose clamps for tightness before refilling.
-
Refill with Coolant:
- Reinstall the drain bolt (make sure the washer/gasket is in good condition).
- Slowly pour in new coolant up to the base of the radiator filler neck, giving air bubbles time to escape.
- Fill the overflow reservoir to the specified level mark.
-
Bleed Air:
- Start the engine and let it idle until it reaches operating temperature (the electric fan may cycle on).
- Watch for air bubbles escaping from the radiator. Top up as needed.
- Shut off the bike and allow it to cool fully. Double-check the coolant level in both the radiator and overflow tank.
-
Final Checks:
- Inspect for leaks. Confirm both radiator cap and drain bolt are secure.
- Recheck coolant levels after your first ride and top off if necessary. The system may purge a small amount of air after the first few heat cycles.
2010 Husqvarna TE250 Owner's Notes
- The TE250 uses a liquid-cooled engine with a double cooler (two radiators) and an electric fan, effective for off-road and enduro riding. Maintain both radiators for optimal cooling efficiency.
- Use only high-quality, aluminum-safe coolants to prevent corrosion of radiator cores and coolant passages. Avoid regular automotive coolants with silicates.
- Coolant changes are especially critical if the bike has been used in muddy or extreme conditions, as debris can clog the radiators and impact cooling performance.
- When checking after the initial heat cycle, expect the reservoir level to drop slightly as the final air escapes the system. This is normal unless repeated drops or overheating occur.
- Consult your owner's manual for recommended service intervals and coolant type specifications. For most trail and enduro use, change coolant every 1–2 years or sooner in harsh environments.
Routine cooling system maintenance will help you avoid overheating, blown head gaskets, or internal engine damage—all critical for the demanding conditions the TE250 is built to conquer.
