What type of coolant sensor? The below answer is for the coolant LEVEL sensor. The coolant TEMPERATURE sensor on my vehicle is located just next to the thermostat housing. On the front top center area of the engine just behind the radiator. Follow the coolant hoses if you have trouble. On my 1995 Jeep Grand Cherokee the sensor is located on the top of the plastic coolant reservoir tank. Look for a small (2-wire?) electrical connector.

There are two separate sensors that play here. the "coolant temperature sensor" and "coolant LEVEL sensor". I suggest confirming which of these was replaced, as it is very common for them to be confused. likely you will find the coolant sensor that was replaced was the one on the engine (temperature); The LEVEL sensor is mounted either in the coolant resivoir or in the radiator. Probably just need the proper sensor replaced.
I have a 1998 Pontiac Grand AM GT that coolant sensor went bad. So how do you change it with out breaking the coolant
No, the electric cooling fans turn on and off by a signal from the coolant temp sensor. The coolant level sensor only illuminates the low coolant light when you are low on coolant.
Check the coolant level in the reservoir. If that's up and the vehicle isn't overheating, you probably have a bad sensor.
