What Causes The Vario 125 Overhead Machine

The overhead of the vario 125 engine is caused by the lack of circulation or water coolant in the engine itself, so that the engine becomes very hot, the heat of the radiator water to boil.

The cause of overhead in the damaged component of the cooling system that is in the engine vario 125, The damage to the components that result in Overhead engine is a component Thermostat as we know that the thermostar serves as the regulator of the speed of water coolant from the radiator of the machine.

The workings of the thermostat if the motor has been run a few kilo meters so the engine becomes 80 ° heat and the thermostat also becomes hot then the thermostat will open by itself to multiply the water coolant from the radiator to the engine.

If the thermostat is damaged even if the engine heat has reached 80 ° peston the cover inside the thermostat will not open so it can not multiply the water coolant from the radiator to the engine therefore it becomes overhead.
