The temperature sensor for a 2005 Buick Terraza with a 3.5L engine is typically located in the engine block. More specifically, it is usually located in the cylinder head, near the thermostat housing.
To locate the temperature sensor, you can refer to your vehicle's repair manual or try the following steps:
Locate the thermostat housing, which is typically located at the front of the engine, near the top.
Follow the coolant hose that is connected to the thermostat housing. The temperature sensor is usually located along this hose.
The temperature sensor may be attached to the hose with a clip or bolt. It is typically a small, cylindrical sensor with wires coming out of it.
If you are unable to locate the temperature sensor, you can try consulting the repair manual or contacting a mechanic for assistance. It's also worth noting that the location of the temperature sensor may vary depending on the specific make and model of your vehicle.
Hello Anonymous
There isn't one. The is no 'cylinder head temperature'. There would be no point in knowing that. There is a water coolant temperature sensor. That is the one that reports to the temperature gauge on the dash and tells you that you are overheating.
The coolant temperature sensor can be found threaded either into the cylinder head or the coolant crossover passage.
Disconnect the negative battery cable.
Drain the cooling system to a level at least below the sensor.
Using the appropriate sized wrench or socket, remove the sensor.
To install, first lightly coat the threads of the sensor with a non-hardening sealer, then tighten the sensor until snug.
Refill the cooling system.
The Coolant Temperature Sensor is located:
Under hood, center, lower engine area, mounted on driver side of engine below intake manifold by the thermostat.
Open up your car manual and turn to the page where there is an illustration of the engine. There you will find the location of the temperature sensor marked in the illustration
Since the coolant temperature sensor is an input device for the engine control computer, and it is located somewhere on the engine, don't you think it would be prudent to mention WHICH ENGINE your 2005 (or is it 2006?) Chevrolet Equinox is equipped with?
I would be happy to help you if I knew for sure what we were talking about...
Don't know your rig but most coolant sensors are near the inlet to the radiator and that is located at the bottom tank.
They don't measure the engine temperature but do sit in the coolant stream as described.
Hope this helped you ??
