The present disclosure provides a method of determining a coolant condition of a vehicle, and more particularly, a method of accurately determining a coolant condition, e.g., a condition in which gas is present in a system and an insufficient coolant condition without a separate additional sensor in a vehicle using an electric water pump (EWP). To this end, the present disclosure provides a method of determining a coolant condition of a vehicle, including, in a vehicle including an electric water pump (EWP) for circulating a coolant, acquiring driving state information of a water pump while the water pump is driven, by a controller, calculating a ripple value of a driving state from the acquired driving state information of the water pump, by the controller, and comparing the calculated ripple value with a reference value to determine a condition of a coolant, by the controller.
