Sensor is in water jacket so you will need to catch coolant after removing sensor.
Properly dispose of old coolant.
Install new sensor and just make a little snug (with open-end wrench)- do NOT over tighten.
Install electric connector and top off coolant.

∙ 14y agoThe coolant temperature sensor can be found on the front of the engine, near the thermostat. Remove the coolant temperature sensor retaining nut, to replace it.
engine coolant temperature sensor is faulty. engine coolant temperature sensor is faulty. engine coolant temperature sensor is faulty. engine coolant temperature sensor is faulty. engine coolant temperature sensor is faulty.
The engine coolant temperature sensor is usually on the front of the engine. The coolant temperature sensor will be in the vicinity of the thermostat housing.
coolant temperature sensor are located where the coolant runs in the block near the thermostat housing normally the connector are on top of the sensor and the sensor itself screws in with a deep socket. The temperature sensor is usaully located where the coolant runs OUT of the engine close to thermostat housing.
Vehicle make, model & engine size needed first.
wher is the engine temperature coolant sensor BUICK 2001
The temperature sensor for the coolant system is located on the front of the engine. The exact location of the coolant temperature sensor is dependent upon the year of the engine.
the coolant temp sensor( cts) reads the temp of the engine and adjust the fuel air mixture depending on the temp. if its cold out the sensor will adjust for more fuel to ease the start of the engine. ADDITIONAL: The Coolant Temperature Sensor measures the temp of the coolant, not the engine. The sensor controls the thermo fans on/off. depending upon temperature. The actual engine temperature sensor is on top of the engine and does not control the fans. If the fans do not switch on at any temperature, disconnect the 2 wire connector from the sensor (Usually at the bottom of the radiator) If fans start up with connector disconnected, replace the sensor.
Your engine coolant temperature gauge has a sensor ( there is also a engine coolant temperature sensor that is used for the computer / PCM )
NOTE: this answer is describing the location of the engine coolant temperature sensor - NOT the coolant sensor in the reservoir that warns when the level gets too low.The coolant temperature sensor is located directly adjacent to the thermostat housing. The thermostat housing is what the upper radiator hose (toward the right side of the engine compartment) connects to. You do not have to replace the reservoir to replace this part, but leaky coolant reservoirs are a common problem on this model.
The 2003 Mazda engine coolant temperature sensor is located on the front of the engine, above the thermostat housing. The sensor will have to wires leading to it.
Coolant temperature sensor is located on the front of the engine. The coolant temperature sensor is a few inches above the thermostat housing.
