ABSTRACT:
A method for controlling a viscous heater for a vehicle. The vehicle has an engine, an engine cooling system for heating coolant, a passage, a radiator and the viscous heater. The radiator heats the passage using heat from the coolant. The viscous heater uses the driving force of the engine to heat the coolant separately from the engine cooling system. The method includes a step of cutting off the transfer of the driving force of the engine to the viscous heater when the engine is being started. The method also includes a step of transferring the driving force of the engine to the viscous heater when the engine is running.
