Disclosed is an engine cooling system, which includes: a water temperature controller assembly (WTCA) coupled to an engine of a vehicle to control a flow of a coolant discharged from the engine; and a first temperature sensor. The first temperature sensor may be configured to: measure one or more temperatures of the coolant discharged from the engine; and generate one or more signals indicating the one or more measured temperatures of the coolant. The engine cooling system may further include a processor configured to: receive the one or more signals; determine a highest coolant temperature measured during a first time period; determine, based on the highest coolant temperature measured during the first time period, whether an amount of the coolant is below a threshold coolant level; and send, based on a determination that the amount of the coolant is below the threshold coolant level, a signal to the vehicle.

The present disclosure provides a cooling system for a hybrid vehicle having an engine and electrical components. The system includes a cooling module having a cooling fan; an engine cooling device having a first line connected to the cooling module and the engine, a first coolant flowing through the first line; an intercooler; an electrical component cooling device having a water pump and a second line connected to the cooling module, the electrical components, and the water pump, a second coolant flowing through the second line; and a controller for controlling operation of the cooling fan and the water pump. The intercooler circulates the second coolant and is disposed in series with the electrical components. Based on a flow direction of the second coolant, the electrical component cooling device includes a bypass line connected to the second line downstream of the cooling module and the second line upstream of the intercooler.
