Mar4ix, Not sure you are asking the right person here. Any way sensor is located beside the dipstick screwed into engine block. As previously stated in this thread sensor should have a black surround covering the spade connector. Well mine has this but still won't work. I will be scowering local scrappies next for a couple of sensors as I have paid out more than enough on this problem so far. It has to be something simple but buggered if I can find it.
good luck with yours
your temp wont rise instantly when you start car, maybe all your 3 sensors are for car with only a light, you need to get sensor for temp gauge or else needle wont move, is wire plugged on the sensor
