markp 0 Posted January 30, 2006 Hi Guys, The water temp gauge on my dash isn't working. (91 G60) Anyone know what sensor it is to check? Cheers Quote Share this post Link to post Share on other sites
Yandards 0 Posted January 30, 2006 It's on the water flange attached to the cylinder head. There should be 2 sensors on top of this held in by U shaped spring clips. You want the sensor closest to the cylinder head and it should be either green/black or a combination of the two. That's assuming it is the sensor and not the gauge, my water temp gauge sticks sometimes after a period where the car has not been used. Quote Share this post Link to post Share on other sites

Supercharged 2 Posted January 30, 2006 It's the black one, take the plug off and measure resistance across the pins, if you get no reading then it's duff, may as well change the blue one as well if so as it will most likely be the same age and that one is critical for the car to run properly.
