* Radiator: The large heat exchanger at the front of the car.
* Radiator Fan(s): Electric fan(s) that draw air through the radiator to cool the coolant.
* Water Pump: A pump that circulates coolant through the engine and radiator.
* Engine Block: Showing the coolant passages within the engine itself.
* Coolant Reservoir/Expansion Tank: A container that holds extra coolant and allows for expansion and contraction as the coolant heats and cools.
* Thermostat: A valve that regulates the flow of coolant to maintain optimal engine temperature. It opens and closes to allow coolant to circulate through the radiator when needed.
* Pressure Cap: Located on the radiator or expansion tank, this maintains system pressure to prevent boiling.
* Hoses: Various hoses connecting all the components, carrying coolant throughout the system. These might be identified individually (e.g., upper radiator hose, lower radiator hose, heater hoses).
* Heater Core: A smaller radiator inside the car's heating system that uses the engine's coolant to heat the cabin.
The diagram might also include:
* Coolant Temperature Sensor: A sensor that monitors coolant temperature and sends information to the engine control unit (ECU).
* Bypass Hose (sometimes): A hose that allows coolant to bypass the radiator when the engine is cold.
The level of detail will vary depending on the diagram. Some diagrams might be simplified schematics, while others might be more detailed, showing specific hose routing or component locations. You would likely find such diagrams in a repair manual for a 1996 Chevy Corsica.
