Technical data of the cooling system (Hyundai Elantra XD)

The closed cooling system consists of a water pump, a cross-flow radiator, a radiator fan with an electric cable, a thermostat, a heater core, hoses and sensors.

The radiator fan with an electric wire is switched on when the contact temperature sensor is triggered.

On models with automatic transmission, some of the fluid circulates through the transmission fluid cooler.
