Match each automotive cooling system component with its primary mechanical function.
- Radiator pressure capMaintains cooling system pressure to raise the boiling point of the coolant
- Heater coreTransfers heat from engine coolant into the passenger cabin
- Cooling fanDraws airflow across radiator fins during low vehicle speeds or idling
- Overflow reservoirCollects excess fluid as coolant expands and returns it when the system cools
Answer
Radiator pressure cap matches maintaining system pressure; Heater core matches heating the passenger cabin; Cooling fan matches drawing airflow across the radiator at low speeds; Overflow reservoir matches collecting and returning expanding coolant.
Each component in a liquid cooling system performs a dedicated function: the radiator pressure cap increases system pressure to raise the coolant's boiling point; the heater core routes warm coolant under the dashboard to heat the cabin; the cooling fan ensures constant airflow across radiator tubes when vehicle motion is minimal; and the overflow reservoir accommodates the natural expansion and contraction of coolant across operating cycles.
