Maybe somebody can help me with this one. My heater core is leaking and I can't find any bolts to take loose to get the plastic pieces off. All I see are these plastic rivet things? A friend of mind replaced his blower motor in his 03 cavalier and said you pull it apart and then have to buy some screws to put it back together? Has anybody else replaced their core? I am not new to heater cores and I replaced the one in our 1994 cavalier fairly easily I didn't even have to pull the dash.

If somebody could post the diagrams of the heater core that would help alot as well. I have my haynes from the 1994 and it doesn't look anything like the 2004.
