How do I change Coolant Level sensor?

[msoto]

Hey guys, this is my first post. Finally got around to it :)

So anyways I just bout my 1987 325i 4door last monday :pimp: and the coolant light on the check panel has been going off. The previous owner went over it with me and it has a bad sensor (Coolant level is fine). I ordered a new coolant level sensor on pelican parts and have no idea how to replace the bad one or where it is located. Any help with this would be great. I would also like to know how to check if my coolant level is good. Pictures would help tremendously. Thanks and have a great day.

#5 is the sensor. It just screws into the top of the coolant overflow tank. To check the coolant level, just look at the side of the tank. There are markings.
