SOURCE: How do I replace the heater core in a 1999 Lumina?

This will take a while, and finding a Haynes Manual for it will make it easier. All but the hoses are removed from under the passenger side dash and it's justa a matter of removing screws and panes until you see it. I wuld diconnect the battery as some of the wires under the dash are AIRBAG. Good luck it's not that bad a job.
