I did my expansion tank last weekend.
Removing the number 6 clip on the bottom of the tank goes a long way to removing the tank....lol
I had no problems actually removing the tank. It came right up.
I was rechecking things and I found that the sensor is not properly installed. I thought I did it right but when I felt underneath it was loose.
I think I remember twisting it to remove it, but when I got under the car and tired to twist it did not respond.
Surprisingly, it is not leaking....
What is the best or should I say, the proper way to install the temperature sensor ?
