Engine Cooling problem
1999 Dodge Neon 4 cyl Two Wheel Drive Automatic 120000 miles

My car is losing coolant. I refil both at radiator and at tank and within 12 hours (total time, not driving time) both are empty and the car overheats. Often there is a puddle under my parked car, but I assume it leaks as I drive as well. This used to be an intermittent problem but has become more regular lately.

The puddle seems to be near the radiator, not the tank, radiator stop-leak fluids do not stop leaks. Any ideas?

I'm not a big fan of the stop leak magic in a bottle thing
they cause more harm then good
have the coolant system pressure check and you may have to replace the radiator or what ever they found leaking
do it before you ruin the engine
