No heat, heater core inlet is hot outlet is cold


Try replacing your thermostat..also you should have a heater lever switch that manually controls the heating unit bolted onto your firewall. Follow your heater hose that's connected from your engine to the firewall. The unit that your lever is connected to is your heater switch. Look for a cable that pulls the unit..... It may be broken..Check it out and LMK how it turns out>>Good Luck!

  • Remove the heater coolant hoses.
  • Remove the cable and/or vacuum control lines (if equipped).

  • Lift the core from the case. Do not use force. Take care not to damage the fins of the heater core when removing.
  • To reinstall the heater core, reverse the removal steps.
