Question about 1999 Pontiac Sunfire
I started having a similar problem last week with the 99 2.4L Sunfire. My low coolant light would light up intermittently. I made sure the system was full to the proper mark. I went to pick my son up Thursday night from football practice, only a 2 mile drive, and everything seemed fine. I went to leave for work on Friday and noticed a puddle of anitfreeze under my car, so I filled the system again. I drove about 30 miles on Friday and all was fine. I drove around town on Saturday, about 10 miles and everything seemed fine, until I went to leave for work on Monday and noticed another puddle under my car, this time it was huge. I filled the system again, drove to work and everything seemed ok. I went to leave work and noticed a small puddle. I went home with no problems, but once again I came out this morning to another puddle. What I am confused about is that the car is not overheating, and not leaking or dumping antifreeze until after it is parked. Please HELP!!
You need to find the source of the leak. it hasn't overheated yet because you keep catching it and re-filling. From your description, it sounds a lot like a bad water pump seal (part of pump) but without physically looking you can't be sure of that. when the pump seal begins to fail, internal pressure while running often will drive the seal tighter against the shaft stopping the leak. as pressure drops as the engine cools, the seal relaxes and permits seepage.
With time, that will change and it will leak all the time.

When i topped off the antifreeze after my oil change i put too much in and there is a hose and when the coolant gets too hot it has to go out cause you to see a puddle on the drivers side, my brother in law is a mechanic he checked the water pump and the radiator..........
