Too Afraid to Ask

A “mystery leak” means the car is losing fluid, but nobody knows what kind yet. The fix starts with figuring out where it’s coming from and what fluid it is.

A “mystery leak” is an unspecified fluid loss that can come from many sources—engine oil, coolant, power steering fluid, transmission fluid, or even condensation. Proper diagnosis usually involves checking fluid levels, looking for the leak origin, and verifying whether the fluid is fresh or old.
