I hope someone can help me with this.
I replaced the expansion tank and now the low coolant light is staying on and the system is full.
I'm not to sure I unplugged the sensor right, when I pulled the sensor out it had a black shaft on the end of the wiring.
Is there a diagram somewhere of how this thing goes together?

If someone knows anything about this I would appreciate any advice.

Thank you, Allison

 

Did the wire come out of the plastic black housing?
