This guide provides a MotoSport-exclusive walkthrough for a proper coolant change on your TX300 with critical tips unique to this MMY dirt bike model. Always work in a well-ventilated area and ensure the engine is cool before beginning.
What Makes the 2024 TX300 Unique?
- The TX300 runs a modern two-stroke engine with advanced electronic fuel injection, which means cooling system care is more important than ever for engine health and consistent power delivery.
- The radiator layout is similar to KTM two-stroke models, but ensure you identify the correct coolant drain bolt specific to the TX300.
- Plastic radiator guards and shrouds may require partial removal for easy accessplan for a few extra minutes if you have these guards installed.
Tools & Supplies Needed
- Quality coolant recommended for aluminum engines (refer to your owner manual for specification)
- Basic hand tools (socket wrench set, screwdriver)
- Catch pan for old coolant
- Shop towels or rags
- Funnel
- Protective gloves and eyewear
Step-by-Step Coolant Change Procedure
-
Let the bike cool down.
Never remove the radiator cap on a hot engine–hot coolant under pressure can cause severe burns. -
Remove the radiator cap.
Locate the radiator cap on the right side of the TX300, unscrew, and set aside. This will allow air in, helping coolant drain freely. -
Find and remove the coolant drain bolt.
Look for the drain bolt located on the right side of the cylinder head, above the power valve. Place a drain pan beneath and slowly loosen the bolt to let coolant flow out. Allow all coolant to drain from both radiators. -
Inspect drained fluid.
Take note of the old coolant's color and clarity. Any heavy debris or contamination may indicate further system cleaning is required. -
Reinstall the drain bolt.
Once empty, clean the bolt and sealing surfaces, then tighten it securely. Use a new sealing washer if required for leak prevention. -
Refill with fresh coolant.
Using a funnel, carefully fill the radiator(s) with the approved coolant. Fill up to the bottom of the radiator's fill neck. -
Bleed air from system.
To remove trapped air, tip the bike left and right several times. Gently squeeze the radiator hoses. Top off coolant again if the level drops. -
Reinstall the radiator cap.
Double-check for leaks around the drain bolt before closing the system. -
Start and idle the engine.
Allow the engine to run at idle for a few minutes. Stop and check the coolant level once more, topping off as necessary. Inspect again for any leaks.
Additional MotoSport Tips for TX300 Owners
- Never mix different coolant colors or types–stick to the specified variety to protect the water pump and internal passages.
- Keep an eye on the radiator guard fitment and shroud alignment during reassembly to prevent cooling system restriction.
- Check for coolant leaks or residue around the coolant lines, especially after your first post-maintenance ride.
- Perform a coolant check every few rides, especially in extreme temperatures or after aggressive races.
A well-maintained cooling system means more riding, less wrenching–and ultimate confidence in your TX300's rugged performance.
