How to solve the high water temperature issue of CFMOTO 650MT?

Installed radiator guard mesh, it is recommended to remove it, because the 650MT is a road-oriented ADV, the radiator is not so easily damaged, and the guard mesh may actually affect heat dissipation. You can try replacing it with a higher-grade coolant.

My CFMoto 650MT also had an overheating issue last summer. First, I checked the coolant level and found it was low. After adding some coolant, the problem was temporarily alleviated. Then, I removed the engine guard and cleaned the radiator gaps, which were completely clogged with lint and insect remains. Later, I also noticed that the fan was intermittently working. Upon opening the relay box, I found a loose wire. After reconnecting it firmly, the fan started normally after a ten-minute test. By the way, it's important to pay attention to rinsing the radiator fins during regular car washes, especially after long trips through farmland areas where willow catkins and rice husks can easily get stuck in the gaps. If overheating persists after ruling out these issues, it might be necessary to consider whether the thermostat is stuck or the water pump impeller is damaged. In such cases, it's best to have a professional mechanic check with pressure testing equipment.
