Evaporator Housing Removal and Installation
REMOVAL
1. Disconnect battery. This must be done to prevent accidental air bag deployment.
2. Using an A/C recovery unit, remove all R-134a refrigerant from the A/C system.
3. Remove air cleaner hose and air distribution duct from the engine.
4. Drain the engine cooling system.
5. Disconnect heater hoses at the dash panel. Plug the heater core inlet and outlet tubes to prevent anti-freeze from spilling on the vehicle interior
during removal. If an appropriate plug cannot be found pull back carpet and use caution when removing unit. Keep the heater tubes elevated to
prevent spillage of coolant.
6. Remove both A/C lines from expansion valve. Use special tool 7193 to disconnect quick connectors on A/C lines. Refer to A/C line removal in
this section for complete procedure. After removing lines cap the expansion valve openings and the A/C hose openings. This will prevent any dirt
or moisture from entering the refrigerant system during servicing.
CAUTION: The lubricant used in this air conditioning system absorbs moisture readily (similar to brake fluid). Do not leave any portion of the
system open for extended periods of time.
7. Remove the three retaining nuts from the studs. These studs project through the dash panel into the engine compartment.
8. Remove right and left instrument panel end caps. These caps are held in place by a series of clips.
