99 plymouth grand voyager low coolant, tried to overheat

I have a 1999 plymouth grand voyager and never had trouble with it overheating. Today while in traffic, the coolant light came on and the temp was in the red. I turned on the heater and the temp started dropping. I stopped to check the coolant and the plastic tank was below the min line. I added it to the max line. I little later it was right back down, so I filled it again. It's now back to the bottom again. I have added almost an entire gallon. I don't see any signs of a leak, but have been told there is no pressure in the cooling system when the hose is pressed/squeezed.

The temp has stayed normal since the first episode.

What could be the problem?

With a very slow leak you might not notice the leak but the radiator would gradually take all the water from the plastic tank and then when the radiator gets low it will overheat. That's why you were able to add so much water. Small leaks are hard to find. You have to look close with a flashlight. Park on concrete so you can see if it's dripping.

What all is involved in replacing the water pump on a 99 Plymouth grand voyager 3.3l

Not much. Jack up on the right side, remove the wheel, and the shroud, remove then serp belt, take out the bolts, and replace the pump. You can try to drain the system first, but we usually catch what we can and add new coolant.

1999 plymouth grand voyager overheats when the ac is on

when the ac is on the computer is looking at pressure in the ac system to control the cooling fan operation if the pressure is increasing the cooling fan is commanded on now if the pressure switch is bad or if the ac system is low on refrigerant it is not building pressure and the cooling fans are not going to come on.

Overheating engine

About two gallons of water/coolant total. If you have to add coolant then there must be a leak. On the expansion tank is a cold and hot level. Good luck

Over heating

It is very likely that the thermostat is stuck closed. This will prevent the coolant from circulating through the radiator.

It is also possible that your radiator fan is not coming on.
