Shop parts for a 2015 Yamaha TW200 Dirt Bike.
Changing the coolant in your 2015 Yamaha TW200 is a crucial part of regular maintenance to keep your bike running at its bestespecially for a model known for its durability and simplicity. The TW200 air-cooled engine uses a straightforward cooling system compared to liquid-cooled bikes, but ensuring the right coolant level and quality will help prevent overheating and extend the engine's lifespan.
Why Change the Coolant?
Over time, coolant loses its effectiveness due to heat and chemical breakdown, resulting in less protection against overheating and corrosion. Regularly changing the coolant ensures optimal operating temperature and prevents rust or mineral deposits inside the cooling system components.
What You Need
- Fresh coolant suitable for motorcyclespreferably a pre-mixed, silica-free formula
- Distilled water (if mixing yourself)
- Drain pan
- Socket set – typically 8mm to 12mm for the drain bolt
- Screwdriver (for panels/fairings if needed)
- Funnel
- Clean rags
- Gloves and safety glasses
Step-by-Step: Coolant Change Procedure
- Preparation:
- Allow the engine to fully cool.
- Place your TW200 on a stable, level surface with the sidestand or a center stand.
- Access the Radiator Cap and Drain Bolt:
- Remove any panels/fairings if necessary to reach the radiator cap. On the TW200, access is generally easy due to its minimalist bodywork.
- Locate the drain bolt at the lowest point of the cooling systemthis is often on the water pump cover.
- Drain the Old Coolant:
- Place the drain pan under the engine.
- Remove the radiator cap to relieve any residual system pressure.
- Unscrew the drain bolt and let all coolant drain completely. Optionally, lean the bike slightly side-to-side to ensure complete drainage.
- Flush the System (Optional):
- If the old coolant is dirty or if it has been a long time since the last change, you can flush the system with a 50/50 mix of distilled water and fresh coolant to remove any deposits, then drain again to clear out residues.
- Reinstall the Drain Bolt:
- Replace the crush washer if needed and securely tighten the drain bolt to the manufacturer's specified torque.
- Refill with New Coolant:
- Using a funnel, pour the new coolant into the radiator up to the base of the filler neck.
- Fill the overflow reservoir to the upper line.
- Burp the System:
- Start the engine with the radiator cap off and let it run for several minutes, occasionally revving the engine gently.
- Watch for bubbles escaping as trapped air is released (the system is being burped).
- Once the bubbling stops, top off the radiator if necessary.
- Reassemble and Double-Check:
- Replace the radiator cap and reinstall any panels previously removed.
- Allow the engine to cool completely, then recheck the coolant level and adjust if needed.
- Dispose of Old Coolant Properly:
- Take the used coolant to an appropriate recycling or hazardous waste facilitynever pour it on the ground or down a drain.
TW200-Specific Tips & Notes
- The TW200 engine is air-cooled in most years, but some international or specialized variants may have supplemental cooling. Double-check your model; for most U.S. models, you're maintaining oil and air cooling, not liquid coolant.
- For the standard TW200, the above instructions apply to the rare models with liquid-cooling systems or for maintenance of any auxiliary coolant-type oil coolers or aftermarket mods. If your model is strictly air-cooled, focus on oil and air filter changes instead.
- Inspect hoses and connections for wear or leakage while performing a coolant change or routine check.
MotoSport Pro Tip
Check your owner's manual for service intervals and coolant recommendations. Performing regular maintenance yourself builds mechanical confidence and helps you better understand your TW200, ensuring reliability on every ride.
