Shop parts for a 2014 Husqvarna TE125 Dirt Bike.
The 2014 Husqvarna TE125 is a high-performance two-stroke enduro machine prized for its lightweight handling and nimble chassis. Regular cooling system maintenance is essential to keep your engine performing in demanding conditions. Below, you’ll find a model-specific guide on changing your coolant, plus key details every TE125 owner should know.
Why Coolant Maintenance Matters on the TE125
The TE125 features a compact radiator system with a total coolant capacity of approximately 1.2 liters (1.3 quarts). This model is designed for aggressive riding, which means regular coolant flushes are crucial to avoid overheating, ensure efficient cooling, and prolong internal component life.
What You’ll Need
- Replacement coolant (compatible with aluminum radiators, engine, and climate requirements)
- Drain pan
- Socket or wrench set
- Funnel
- Clean shop towels
- New radiator cap gasket and drain bolt washer (recommended)
Step-by-Step Guide: Draining – Flushing – Refilling the Coolant
- Prep the Bike: Ensure the motorcycle is on a stable, upright stand with a cool engine.
- Remove the Radiator Cap: Slowly remove the radiator cap to relieve any residual pressure.
- Locate the Drain Bolt: On the TE125, the coolant drain bolt is at the bottom of the water pump (right side of the engine). Position your drain pan beneath it.
- Drain Coolant: Remove the drain bolt (and any associated washer). Allow coolant to flow out completely. To improve drainage, gently rock the bike side to side.
- Inspect – Flush if Needed: If your coolant appears dirty, refill the radiator with distilled water, reinstall the drain bolt, run the engine briefly, and drain again to flush contaminants.
- Reinstall Drain Bolt: Replace the washer if needed and torque the drain bolt to factory spec. Check for leaks.
- Refill Radiator: Fill the radiator slowly with new coolant until it’s level with the bottom of the filler neck. The TE125 takes about 1.2 liters—refer to your manual for specifics. Burp any air by gently squeezing radiator hoses.
- Bleed Air Out: Start the engine and let it idle with the radiator cap off. Watch for air bubbles as the thermostat opens. Top off coolant as level drops, then reinstall the radiator cap.
Some air may escape into the reservoir after riding. Check and top off after your first complete heat cycle. - Dispose Properly: Used coolant is hazardous—take it to an approved recycling facility.
Model-Specific Tips for the TE125
- When reassembling, always use a fresh drain bolt gasket to avoid leaks.
- Avoid overfilling the radiator to prevent overflow when the bike heats up.
- The expansion tank on the TE125 also functions as an overflow and recovery system—after riding, re-check the level once the engine is completely cool.
- If you notice frequent drops in coolant level, inspect hoses, radiator, and water pump for possible leaks or gasket wear.
Final Check
- After a 15-20 minute ride, allow the engine to cool fully, then confirm coolant levels in both radiator and reservoir.
- Routine system inspection and coolant changes (at least annually or per your manual) are highly recommended for all off-road use.
