  Q: How to replace the heater core on Nissan Rogue?

  A: Replacement of the heater core is a difficult procedure for the home mechanic, involving removal of the entire dashboard, console, and many wiring connectors. If you attempt it at home, keep track of the assemblies by taking notes and keeping screws and other hardware in small, marked plastic bags for reassembly. Have the air conditioning system evacuated by a properly equipped shop. Disconnect the cable from the negative terminal of the battery. Drain the cooling system. If the coolant is relatively new, or is in good condition, save it and re-use it. Move aside the lower dash insulation to access the heater core pipes. Disconnect the heater hoses from the pipes protruding through the firewall. Disconnect the refrigerant lines from the evaporator. Plug all open fittings of disconnected lines to prevent entry of dirt and moisture into the lines. Remove the steering column. Remove the entire instrument panel assembly. Disconnect the connectors for various components. Disconnect the evaporator drain hose. Remove the instrument panel support beam and the heating and air conditioning unit as a complete assembly, then place the assembly on a work bench. Handle the heating and air conditioning unit carefully during removal to avoid accidental damage to the interior. On 2014 and later models, remove the front foot duct screws and separate the duct from the left side of the heating and air conditioning unit. Remove the heater core insulation to expose the heater core pipe bracket screws. Remove the heater core pipe bracket screws and remove the bracket, if equipped. On 2014 and later models, remove the heater core cover fasteners and cover. Slide out the heater core and remove it from the HVAC housing. Installation is the reverse of removal, noting the following: Do not use old O-rings for the refrigerant lines, replace with new ones and apply compressor oil to them before installation. Refill the cooling system. Reconnect the battery and perform the necessary re-learn procedures. Check for leaks and proper system operation. Check the operation of all electrical components of the steering column and dash. Have the air conditioning system recharged by the shop that discharged it.
