Shop parts for a 2013 Husqvarna TE511 Dirt Bike.
Routine coolant changes keep your 2013 Husqvarna TE511 running cool and performing at its best, protecting engine components from overheating and corrosion. The process is straightforward with common shop tools and a few tips specific to this high-performance dirt bike. Below is a proprietary MotoSport guide aligned with the TE511's official specifications and quirks. Always reference your owner's manual before service and use appropriate safety gear.
What's Unique About the TE511?
- Large-displacement engine with high operating temperatures: Regular coolant checks are crucial, particularly if the bike sees tough off-road use.
- Unusual frame-mount radiators: The TE511's radiator design means that accessing the coolant system may take a bit more patience than smaller trail bikes.
- Specific coolant level check: The cold coolant level should be approximately 10 mm above the radiator cells, visible through the left radiator cap when the bike is upright.
Tools & Supplies You'll Need
- Allen wrenches/sockets (to remove covers/panels as needed)
- Chemical-resistant gloves & eye protection
- Coolant drain pan
- OEM-recommended coolant (silicate-free, compatible with aluminum components)
- Distilled water (for flushing, if desired)
- Torque wrench
- Clean rags/wipes
Step-by-Step: Changing the Coolant
- Prep the motorcycle. Place the bike securely on a stand, engine cold. Never attempt to open the radiator when hot to prevent burns from pressurized steam or coolant.
- Remove necessary panels. If access to the radiator cap or drain bolt is restricted, remove the seat and left shroud.
- Open the radiator cap. With the bike upright, carefully remove the left radiator cap to relieve any residual pressure.
- Locate and remove the drain bolt. There is usually a drain bolt at the lower right side of the cylinder near the water pump or on the right side of the engine. Position a drain pan underneath. Slowly loosen then remove the drain bolt to allow the old coolant to drain completely.
- Inspect drain bolt/sealing washer. Clean the drain bolt and inspect its sealing washer. Replace the washer if it is damaged before reinstalling.
- Optional: Flush the system. If fluid is dirty or contaminated, flush with distilled water. Reinstall the drain bolt, refill with distilled water, run the engine briefly (do not overheat), let cool, then drain again. Repeat as needed for clear water.
- Reinstall the drain bolt. Tighten the drain bolt to the torque spec in your service manual using the torque wrench. Do not overtighten.
- Refill with coolant. Pour the recommended coolant into the radiator until it sits about 10 mm above the top of the radiator cells on the left side. Replace the cap.
- Bleed air from the system. Run the engine with the radiator cap off for a short period to allow trapped air pockets to escape (watch for air bubbles). Top off coolant as needed, then securely fit the cap.
- Check for leaks and test run. Reassemble any removed panels. Start the engine and let it reach full operating temperature, watching for leaks and confirming the cooling fan cycles on (if equipped). Let the motor cool and check the coolant level again – top up if required.
Additional TE511-Specific Tips
- Radiator check is on the left, drain is on the right: Unlike some bikes, checking and draining are on opposite sides.
- This model's high-compression engine is sensitive to overheating: Always use manufacturer-specified coolant and keep the radiators clean from debris after muddy rides.
- Check the water pump weep hole: A leaking weep hole indicates a failed seal or bearing – fix before refilling with new coolant.
Maintaining the cooling system is fundamental for Husqvarna reliability. With just a bit of care, your 2013 TE511 will keep conquering tough trails for years to come.
