Zorluk: OrtaCooling System

Modern automotive cooling circuits incorporate secondary heat exchangers and flow regulation passages alongside the primary engine radiator. Match each cooling system component on the left with its corresponding operational role on the right.

  • Thermostatic fan clutchModulates cooling fan speed based on the temperature of air drawn through the radiator core
  • Coolant bypass passageRecirculates coolant within the cylinder block and head during warm-up to prevent localized overheating while the thermostat remains closed
  • Heater coreExtracts thermal energy from hot engine coolant to warm ambient air ducted into the passenger compartment
  • Transmission fluid coolerDissipates automatic transmission heat directly into the engine coolant circuit within a dedicated radiator tank chamber

Cevap

Thermostatic fan clutch matches modulating cooling fan speed based on air temperature; Coolant bypass passage matches recirculating coolant internally during warm-up; Heater core matches extracting thermal energy to warm passenger compartment air; Transmission fluid cooler matches dissipating transmission heat into the engine coolant circuit.
Each component serves a distinct role in automotive thermal management: the thermostatic fan clutch controls airflow across the radiator fins; the bypass passage maintains internal circulation when the thermostat is shut; the heater core warms cabin air using coolant heat; and the transmission cooler regulates transmission oil temperature via the radiator tank.

Adım Adım Çözüm

1
Identify the primary function of the thermostatic fan clutch.
It engages or slips mechanically depending on air heat exiting the radiator core, controlling airflow without draining continuous engine power.
The fan clutch regulates airflow based on thermal demand rather than running at full engine RPM at all times.
2
Determine the role of the internal coolant bypass passage.
It routes coolant back to the water pump intake when the thermostat blocks flow to the radiator.
Continuous circulation inside the block prevents localized boiling around the combustion chambers during cold starts.
3
Identify the heat transfer purpose of the heater core.
It acts as a secondary cabin heat exchanger utilizing hot engine coolant.
Engine waste heat is repurposed through this core to heat the passenger compartment.
4
Identify the purpose of the transmission fluid cooler.
It transfers automatic transmission fluid heat to the engine coolant inside the radiator end tank.
Liquid-to-liquid heat exchange stabilizes transmission fluid operating temperature.
