Q: How to remove and install a condenser in a Nissan Quest's air conditioning system?
A: Have the refrigerant discharged and recycled by an air conditioning technician. Disconnect the negative cable from the battery and drain the cooling system. Disconnect the condenser line and discharge line from the condenser. Cap the fittings on the condenser and lines to prevent entry of dirt or moisture. Remove the Radiator. Remove the condenser retaining bolts. Lean the condenser back toward the engine and remove it from the vehicle. Installation is the reverse of removal. If a new condenser was installed, add 1 to 1.7 ounces of fresh refrigerant oil. Have the system evacuated, charged and leak tested by an air conditioning technician.
