* Upper Radiator Hose: Connects the engine to the top of the radiator.
* Lower Radiator Hose: Connects the bottom of the radiator to the engine.
* Heater Hoses: These hoses run to the heater core inside the vehicle's cabin. Leaks here might not be immediately visible near the engine.
* Water Pump Hose(s): The hoses connected to the water pump itself can leak.
* Thermostat Housing: While not strictly a hose, leaks from the thermostat housing are common and can look like a hose leak.
To determine the exact location of the leak, you'll need to visually inspect the entire coolant system. Look for wet spots, stains, or dripping coolant. Sometimes a pressure test of the cooling system is necessary to pinpoint a leak that is difficult to see.
