    lines are disconnected and from engine side you can feel a soft foam around the lines to seal the holes off. so don't think there is any tar there.i pulled heater core cover off and core.but can't get evaporator cover off.i can pry open the front side of that compartment but i dont know what is holding it together against the firewall.does it somehow snap together in the back to eliminate screws back there?

    When draining engine coolant, keep in mind that cats and dogs are attracted to ethylene glycol antifreeze and could drink any that is left in an uncovered container or in puddles on the ground. This will prove fatal in sufficient quantity. Always drain coolant into a sealable container. Coolant should be reused unless it is contaminated or is several years old.
  3. Disconnect the heater hoses. Be careful not to damage the core by pulling on the hose to remove. Cut the hoses if they will not come off easily.
  4. Remove the instrument panel.
  5. Disconnect the resistor assembly.
  6. If possible, disconnect and move the duct (non air conditioning) or the evaporator housing (air conditioning) to the right to gain clearance for the heater unit. If equipped with air conditioning, do not disconnect air conditioning system until absolutely necessary. Refer to Section 1 for discharging, evacuating and recharging the system.
  7. Remove the instrument panel stay and heater unit.
  8. Disassemble the heater unit by removing the duct, mode control case, core assembly and heater core. To install:
