Check connector and wire for shorts/breaks.
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.
It is old and needs flushed and replaced.
The coolant temperature sensor on a 2001 Jeep Cherokee is located in the intake manifold. It monitors the flow and temperature of coolant through the engine.
the coolant temperature sensor is faulty. It will need to be replaced

Be careful there is a temperature coolant switch mounted next to the thermostat housing. I thought this was the sensor and replaced it by mistake. There is another sensor.
Right around 205 degrees on a warm day.
You need to check coolant temperature sensor and the water pump.
Under hood, center, upper engine area, mounted in driver side of water outlet
The engine coolant temperature sensor is the sensor that is screwed into the thermostat housing on the top front of the engine.
The engine computer uses the signal from the coolant temperature sensor to decide when to activate the radiator fan relay.
The light is not a coolant light, it is a temperature light which comes on when the temperature of the coolant is above the limits. In other words you engine is overheating. Can be defective thermostat, bad water pump, clogged radiator, or blown head gasket.
