Water pump: The water pump is responsible for circulating coolant throughout the engine. If the gasket or seal fails, it can cause coolant to leak.
Heater core: The heater core is a small radiator located behind the dashboard that provides heat to the cabin. A leak in the heater core can cause coolant to leak onto the floor of the car.
Cylinder head gasket: The cylinder head gasket seals the cylinder head to the engine block. If the gasket fails, it can cause coolant to leak into the combustion chambers or oil passages.
Freeze plugs: Freeze plugs are small metal plugs that seal openings in the engine block and cylinder head. If a freeze plug fails, it can cause coolant to leak.
Radiator: The radiator is a large metal tank located at the front of the car that holds coolant. If the radiator is damaged or corroded, it can cause coolant to leak.
Coolant hoses: The coolant hoses carry coolant from the radiator to the engine and back again. If a hose is cracked or damaged, it can cause coolant to leak.
Thermostat housing: The thermostat housing is a metal housing that contains the thermostat. If the gasket or seal on the thermostat housing fails, it can cause coolant to leak.
Water bypass pipe: The water bypass pipe is a metal pipe that connects the water pump to the engine block. If the bypass pipe is cracked or damaged, it can cause coolant to leak.
To determine the exact source of the leak, you will need to inspect the engine bay for any visible signs of coolant. You may also need to use a pressure tester to identify the source of the leak.
