i dont know what i did wrong when i did it -- it flowed like a frickin water dam -- it was pouring out the first time -- and even after i released the pressure on the expansion tank - anywho i still wanna know what i did wrong -- granted i got it changed but -- i lost a hell of a lot of fluid!Just changed my sensor. Very easy, you just have to disconnect the intake hose so you can get your hand down back to unhook the connector. I lost just a small amount of coolant, probably not enough to have to top up the coolant tank.
I didn't have a problem with the temp gauge or buzzer, just a CEL and when I had it scanned the code was coolant temp sensor.
I'll refer you and others here to my thread again, where I ran into some of these problems.The sensor looks black to me, even removed the electrical connector thinking I would see something to give me a clue but no, its not blue or green. Is the color only verified once the sensor is pulled out?
