Hello- on most VW models the heater core - sometimes called a matrix - is buried deep in the dashboard area. It is renowned as being almost the most difficult thing to access as car makers start a production line by putting the heater core on a stand and then build everything else around it.

You would have to remove the steering wheel, then the dashboard... and I would check all other possible faults before trying to replace it. What are the symptoms which make you want to find it?

Let me know. Thanks, D.

Where is the heater core and hoses located on a 2002 jeep liberty?


The heater core is located on the passengers side of the vehicle inside the air box. Dash removal is necessary to replace the heater core. You should see two rubber lines going into the firewall around the upper corner on the passengers side.

How do you replace heater core on chrysler 300m 2002


If it is necessary to remove the heater assembly, the cooling system must be drained before removing the heater core.
When a heater core leaks, a new heater core is installed or the old one repaired.
Heater Housing
  • The heater housing is usually under the dash and must be removed to gain access to the heater core.
  • Procedures for replacing the heater core vary with the year, make, and model of car. It threfore necessary to consult the manufacturer's repair manuals for the proper procedure for replacement.

  • Remove the access panels(s) or the split heater/air conditioning case to gain acess to the heater core.
  • Remove the heater coolant hoses.
  • Remove the cable and/or vacuum control lines (if equipped).
  • Remove the heater core securing brackets and/or clamps.
  • 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.
