Same problem I'm having. 2.2 - I've found the one that goes to the dash (on thermostat housing - one with pig tail and wires) but I think there is another somewhere on the head that goes to the computer - which I also need help finding. P & T Y
located coolant temp sensor
On the 4.3L it is located next to the thermostat housing. The electrical plug to it has two wires.
where is the temperture sensor located on a 2002 chevy trailblazer with a 4200 motor
The 1992 Chevy 3500 temperature sensor is located on the front of the engine. The temperature sensor will be in the vicinity of the thermostat housing.
The coolant temp sensor screws into the thermostat housing. This is located where the top radiator hose connects to the engine.
Where is the temp sensor on a 91 Chevy astro
If it has a 4.3L engine the temp sensor is located next to the thermostat housing.
The coolant temp sensor on a 2003 Chevy S10 V6 is located on the front of the intake manifold. To replace simply unscrew the old sensor and screw on the new one.
It is located behind the grill but in front of the radiator on the passengers side of the vehicle.
could be a bad sensor a bad gauge or a broken or disconnected wire
The themostat is located in the top rad hose on the engine side, but I don't know about the sensor. In my 91 the coolant temp sensor is in the thermostat housing and the engine temp sensor is on the block.
Could be the temp sensor..there could also be an oil pressure sensor at the top, back,or the block.
