We have a 1999 Chevrolet Express 1500 van with a 5.7 engine. I have noticed the coolant in the reservoir has occasionally gone down dramatically to empty within one day. However it does not do it all the time.
Friday I drove to the next city over and then made 30 to 60 minute stops throughout the day and returned back home. I check the level twice while on the trip and then again Saturday morning after it had set all night. The reservoir did not lose any fluid. I probably put on about 120 miles that day.
Later Saturday, I took the van on two short trips in my town and that was it. I did not drive it Sunday at all. Monday morning the reservoir was completely empty. I can see some signs of fluid on the bottom of the engine.
