Sensor cost around 45 to 50 dollars but you can remove your old one and clean it with some carburetor cleaner or degreaser and a q-tip. It saved me some money.

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.
Low coolant or bad sensor
Either do to a coolant leak or a failed coolant level sensor.
Low coolant or a defective sensor
Underneath the alternator
In answer to your question the coolant temperature sensor on a 2000 Pontiac grand am with a 3.4L engine, is located on the rear of the engine above the flywheel. It is located just behind the what I believe is the alternator.
On a 1991 Pontiac Grand Prix, the coolant temperature sensor is typically located near the thermostat housing on the engine block. It is usually found on the intake manifold or cylinder head, depending on the specific engine configuration. This sensor monitors the engine's coolant temperature and sends data to the engine control unit for optimal performance. If you're having trouble locating it, consulting a repair manual specific to your model can provide further guidance.
