Identifying the Source of the Leak
The first step in fixing a car leaking coolant is to locate the source. Look for puddles of bright green, pink, or orange fluid under your car. The color depends on the type of coolant used. Check the coolant reservoir level; a low level indicates a leak. Inspect hoses, the radiator, water pump, and thermostat housing for signs of wetness, cracks, or corrosion. A pressure test can help pinpoint leaks in the cooling system.

Common Causes of Coolant Leaks
Several components can cause coolant leaks. A cracked radiator is a common culprit. Hoses can become brittle and crack over time, leading to leaks. A faulty water pump seal can also result in coolant loss. The thermostat housing can crack or develop leaks around the gasket. Lastly, a leaking heater core can cause coolant loss and a sweet smell inside the cabin.
