I just bought a 94 wrangler yj and noticed the heater core is leaking antifreeze in the floor board. How do I change the heater core?
 
Pop the hood
look for 2 hoses going from the engine to the fire wall. Those are the heater hoses. Unhook them.
Open the passenger side door
Look under the dash. That little radiator looking thing is the heater core.
Unbolt it and unhook the control wires if needed
pull it out
buy a new one
install it
hook up heater lines
add coolant
