Changed the sensor today. Took all about 5 mins, I used a 1" 6 point deep socket, cranked it out, put the new one in. Started the car and let it warm up for about 10 mins. Went and looked at the gauge, still no reading. Took the car for a short drive and still nothing. Now I'm thinking it might be the gauge cluster. I park the car, and put on the AC on cause it's hot outside. I flipped on the flashers real quick to test if they work and I the temp gauge shot up to where it was supposed to be.... I'm like WTF? It dipped down and then went up a couple times after I shut the AC and flashers off. At that point, I had enough and went inside for a nice cold beer. LOL...
