hi all. i hope someone can help me. i have a 92 corvette and it leaks coolant. i changed the water pump and thermostat. that seemed to stop it for a while. then just yesterday while on a day cruise it started again. i kept filling it back up with water just to make it home, after about 50 miles of driving it stopped leaking. i drove over sixty more miles without a drop of leakage. when it leaks it will drain the coolant rather quickly. i don t think it is over heating because as soon as the low coolant light comes on i filled it back up. i just don t understand it stopping. if it continued to leak it could be a bad water pump. i put a new gm pump in just two months ago. any one have any answers?
