There are two parts to this. the Temp sensor is just under the air intake. one clip that has two wires on it. You will need a deep well socket. I think a 3/4 will do it. You might have to remove the air breather to see it as it's very deep under the air intake. Now there is also a "temp switch" it's about at the same height as the sensor on the motor but it's on the fire wall side. It uses the same wire harness so just follow that as it's the second thing in line to the sensor. It has only one wire going to it. I replaced the sensor and the gauge didn't do anything. Then I got the "switch" and it's all ok now. each part was 20 bucks at auto zone. Easy to fix.
