Question about 1995 Pontiac Grand Prix
If you look on the under side of the water pump you will see a small hole. This is called a weep hole. If the seal in the water pump shaft is going out it will usually leave a trail of coolant from the hole. When you start you car in the morning the coolant is cold. As the coolant warms up the thermostat opens and releases the hotter coolant to the radiator. Start the vehicle when cold with the radiator cap removed let it warm up as normal. You can purchase a cheap automotive thermometer to place in the radiator to tell you when the coolant temp is rising. When the thermostat opens the pump will push the coolant through the radiator. You can usually actually see this if you look into the top of the radiator if you crack the throttle sharply. If your thermostat is opening and the water pump is working and you have an overheating condition I would check to see if the tubes in the radiator are restricted.
