leaks water from somewhere on the ground when the car is in the garage used to take about a half gallon after driving. no water in oil no smoke out of tailpipe. just got it out for the spring radiator empty looked everywhere i cannot find a leak. getting frustrated. any suggestions.

Get some UV Leak Detection Dye for cooling systems and install in your radiator. Shine a fluorescent light to see where it is coming from. Available from most Auto parts stores.



Ensure you are not overfilling the radiator.

Slight leak in my radiator, the drips 'glow' under fluorescent light, making it easy to trace.
