This is a CFMoto OEM-spec Thermostat, part number 0MQ0-022500, sold as a single unit. This thermostat is installed in the engine cooling system, using a wax-pellet element to automatically regulate coolant flow based on temperature. It controls the switching between the small and large coolant circulation loops, allowing the engine to reach and maintain optimal operating temperature quickly — a critical component of the engine thermal management system.

Over time, the original thermostat may fail due to wax pellet leakage, spring fatigue, or valve sticking. Common failure modes include: thermostat stuck open (engine warms up slowly, poor cabin heat, increased fuel consumption) or stuck closed (engine overheating, coolant boiling, potentially causing severe engine damage). Replacing with an OEM-spec thermostat at recommended intervals is an essential maintenance practice to ensure proper engine operating temperature and prevent overheating or overcooling.

• ✅ OEM Original Spec: Manufactured to CFMoto original technical standards; opening temperature, lift, and sealing performance match the genuine part exactly.
• 🛡️ Precision Wax Element: Made with high-quality wax for accurate temperature response and reliable opening/closing action.
• 🔧 Direct Fitment: External dimensions and mounting interface match the original for a direct replacement with no modifications.
• 💪 Corrosion-Resistant Design: Metal components are rust-protected, and the sealing ring resists coolant corrosion for long-term reliability.
• 🔄 Direct Replacement: Replaces thermostats that are leaking, sticking, or otherwise failed.

✅ Typical signs you need to replace the thermostat:
• Engine warms up slowly — coolant temperature takes a long time to reach normal operating level.
• Cabin heater output is weak or noticeably reduced.
• Engine overheats — temperature gauge reads high or coolant boils over.
• Significant temperature difference between upper and lower radiator hoses (upper hot, lower cold — thermostat stuck closed).
• Fuel consumption increases abnormally with degraded emissions.
• Thermostat has exceeded the recommended replacement interval (typically 50,000–80,000 km or per maintenance schedule).
Thermostat failure can cause severe engine damage. Replace promptly if any of these signs appear.

✅ Installation Tips:
1. Confirm the thermostat is the correct 0MQ0-022500 matching the original.
2. Allow the engine to cool completely before starting work to avoid burns.
3. Drain enough coolant so the level is below the thermostat housing.
4. Remove the thermostat housing cover or housing, and take out the old thermostat and seal ring.
5. Clean the sealing surface on the housing, removing old sealant or debris.
6. Install the new thermostat (with new seal ring or sealant) into the housing in the correct orientation.
7. Note the arrow or marking on the thermostat — it usually points toward the engine (refer to the service manual).
8. Reinstall the thermostat housing cover or housing, and torque bolts to OEM specifications.
9. Refill coolant to the proper level, start the engine and bleed air from the system, and check for leaks.
Installation requires mechanical skill; professional installation recommended. Improper installation may cause coolant leaks or engine overheating.
