Your vehicle’s heating system absorbs excess engine heat through a mixture of water and antifreeze called coolant. Hoses carry the coolant from the engine to the radiator, where heat is expelled outside. The heating system circulates the heated coolant to the heater core in the dashboard, which directs the warm air into your vehicle’s interior compartment. This cycle depends on the heater hoses carrying the coolant from the engine to the heater core, where the heat can finally warm the inside of your vehicle. Heating system components include the heater fan, water pump, thermostat, heater hoses, and heater core. These components regulate the internal temperatures of the engine and vehicle cabin. The water pump pushes coolant to the engine block. Coolant flows from the cylinder heads to the heater core, where the heater fan directs the warm air outflow into the vehicle’s cabin. Once the heat is transferred from the coolant into the vehicle, the coolant returns to the water pump where it continues to circulate through the system. During a heating system service, our service staff will examine all working components to diagnosis and identify the problem.
