Its on a part called the "gooseneck". follow the upper radiator hose to the engine. It hooks to the gooseneck which houses the thermostat. The sensor will have a wired plug hooked to the top. This is an incorrect answer above. The temp sensor is in the driver's side head,between #1 & 3 cylinders. There is one green wire going to it.
Under the thermostat
Yes, the 1999 Chevrolet Monte Carlo is equipped with a coolant temperature sensor. This sensor monitors the engine's coolant temperature and sends data to the engine control module (ECM) to help manage engine performance and efficiency. If the sensor fails or malfunctions, it can lead to issues such as poor fuel economy or overheating.
On a 2001 Monte Carlo it is located on the radiator just below the radiator cap.
Check coolant level in recovery tank Perhaps a bad sensor. Sensor located in coolant recovery tank
the coolant sensor is in the radiator on the passanger side the oxygen sensor is in the exhaust system on the manifold and the pipes and sometimes both
The temperature sensor is located on the driver's side under the radiator hose, on top of the intake manifold.
Look where the thermostat is attached to the intake manifold
The intake air temperature sensor is located in between the mass air flow sensor and the air filter. Its the sensor in the plastic tube that connects the two.

In a 1977 Monte Carlo, the temperature sensor is typically located on the engine block, near the thermostat housing. This sensor monitors the engine's coolant temperature and sends the information to the dashboard gauge. It can usually be identified by its electrical connector and is often found on the driver's side of the engine. If you need to replace or inspect it, ensure the engine is cool to avoid burns.
