Hello. I have a 1999 Jeep Grand Cherokee and everytime I drive my tempature thermostat keeps going up and down. Maybe I need a new one? I'm not sure. I just had my radiator replaced and now i see coolant leaking under the car. I didn't change the thermostat when I had got the radiator replaced. and the heat still works when the thermostat goes all the way down. Please help
