most are near the water outlet housing.
..... sense water temperature?
On my 2000 International with a Detroit series 60 engine the water temperature sensor is on the back of the engine, passenger side in the cylinder head. Gears
1. Water temperature sensor Intake air temperature sensor cylinder head temperature sensor exhaus temperature sensor and catalytic sensor
There are several temperature sensors on a 2001 Chevy Monte Carlo. A temperature sensor for outside temperature is located near the passenger side wheel underneath the vehicle. A manifold temperature sensor is located in the manifold. There is also an air temperature sensor in the hose that leads from the air filter to the motor. Still another temperature sensor is the thermostat in the upper radiator hose near the water pump.
the sensor for the gauge should be by the thermostat housing,the sensor for the ecm should be on the right rear of engine above exhaust manifold screwed into head
The Water Temperature Sensor Assembly is located in the thermostat housing. It's explicit location is shown as Ref #15 in the diagram listed in the 'Sources and Related Links' section of this answer. (located below)
The Temperature sensor for the computer is on top the head. The temperature sensor for the temperature gauge is located under the Thermostat housing.
Most engines have the temperature sensor either at the top water inlet or on the side of the block. Remove the sensor wiring, then unscrew the sensor to replace it.
Your oil temperature gauge will connect to the oil pressure sensor. The water temperature gauge will hook up to the water temperature sensor. The oil pressure sensor will be on the left-hand side of the engine and the water temperature sensor will be on the front of the engine.
An air temperature sensor in an automobile is very important. The temperature sensor detects the external temperature. The external temperature is important because of the manner in which the car's computer mixes air and water.
The water temperature can be different from the air temperature in a specific location. Factors like sunlight, wind, and depth of the water can affect the temperature of the water, making it either warmer or cooler than the air temperature.
