Q: How to remove and replace the air conditioning expansion valve in the Honda Fit?
A: Have the refrigerant discharged at a dealer service department or an automotive air conditioning repair facility. On 2008 and later models, disconnect the air conditioning lines from the evaporator core. Cut the joint caps holding the tube to the evaporator at the designated areas and remove the stops, disconnect the air conditioning lines from the evaporator core. Discard the old O-rings and joint caps. For 2009 and later models, remove the glove box and the glove box frame, then cut the plastic brace from the glove box aperture. Disconnect the electrical connector from the Blower Motor. Remove the passenger's heater duct. Remove the blower motor and housing as a unit. For all models, remove the screws on the expansion valve cover and remove the cover. On 2009 and later models, remove the seals from the cover, discard the old seals and replace upon installation. Remove the refrigerant line/expansion valve bolts and disconnect the refrigerant lines. Remove the expansion valve and discard the O-rings. Installation is the reverse of removal. Tighten the expansion valve bolts. To prevent leaks in the air conditioning system, do not use old O-rings. Replace them with new ones and apply R-134a-compatible refrigerant oil to them before installation. Have the system evacuated, charged and leak tested by the shop that discharged it.
