Identified Causes
Radiator Leak
80%The radiator is a common source of coolant leaks. Cracks or corrosion can develop over time, allowing coolant to escape and form puddles.
Hose Leak
75%Coolant hoses can degrade, crack, or become loose over time, leading to leaks. These leaks often appear as puddles directly beneath the hoses.
Water Pump Seal Failure
60%The water pump circulates coolant, and its seals can fail, causing coolant to leak out, often from the front of the engine where the pump is located.
Heater Core Leak
50%The heater core is part of the cooling system and can develop leaks. A leaking heater core can sometimes cause a sweet smell inside the cabin and wetness on the passenger side floor.
