Any Experience persontell me where and what is the problem?
do not remove the thermostat valve, it was put into the design for a reason, also do not use plain water, coolant was put into the design for a reason too.
the thermostat ensures a "minimum" of 80C operating temperature on the engine, the coolant ensures that the engine is protected against corrosive nature of water as cooling medium.
The engine does trap air in the top part - honda has provided a bleeder bolt for this engine which is located at the top of the coolant outlet on the cylinder head, use it.
