Car Leaks

Coolant, oil, transmission, AC and brake fluid leaks

90 expert guides

Finding a puddle under your car spikes anxiety. Not all car leaks are emergencies — clear water from AC condensation is normal. A dark oil spot might be a minor gasket seep.

Key to diagnosis: color and location. Green/orange = coolant. Dark brown = oil. Red/pink = transmission. Clear and oily = brake fluid (emergency).

Each guide helps identify the fluid, find the source, assess urgency, and decide on the fix.
