How do you replace heater core - 2002 Saturn Sl
First your going to drain all the coolant/antifreeze. 2nd your gonna look under the hood against the passenger side firewall and locate the 2 black heater hoses those will be what are attached to your heater core but don't do anything to them, go in the passenger compartment and remove the parts of the dashboard and glove box until you see what looks like a miniature radiator that's gonna be your heater core. It may have some sort of casing around it so just track the hoses and remove and replace. Pretty simple just a pain to get too in most vehicles....
