At some point in my car's life the piece that holds the sensor apparently went missing... someone tried to do it right and still zip tie it to the front of the car (circled, but doesn't that piping get hot?). My displayed temp fluctuates a lot especially when the car is stopped at a light -- it will start climbing up 1 degree at a time. Can anyone help with P/N(s) for the piece(s) I'm missing that would hold the sensor? I can see the empty bracket hole that the piece(s) should mount to.
