How to Replace the Heater Core in a 2000 Dodge Intrepid


Your 2000 Dodge Intrepid has a heater core that operates much like a radiator. Heated coolant passes from the engine through the heater core's winding tube. The heater core's tubes have fins, which help to transfer more heat to air by creating a greater surface for heating purposes. The heat that is exchanged within the heater core is then transferred to the cabin via the vehicle's ventilation system. Replace the heater core at the first sign of problems. If you fail to properly maintain the heater core, the window defroster could stop working when you need it most.

Things You'll Need

  • Ratchet and socket
  • Flathead screwdriver
  • Phillips screwdriver
  • Drain pan
  • Disconnect the negative battery cable using a ratchet and socket, then remove the radiator drain hose clamp, which is located beneath the radiator, using a flathead screwdriver. Pull the radiator hose and drain the coolant into a drain pan.

  • Remove the radiator hoses from the radiator and firewall connections using a flathead screwdriver, then climb into the cabin and remove the coin tray by hand.

  • Unscrew the screw from behind the coin tray using a Phillips screwdriver, then open the glove box and pull the hinges upward until the dash assembly separates from the dash.

  • Locate the heater core on the passenger side of the dash, then unscrew the heater core cover using a Phillips screwdriver.

  • Unbolt the heater core using a ratchet and socket, then pull the heater core out and remove the electrical connections by hand.

  • Attach the electrical connections to the new heater core, then bolt it in place using a ratchet and socket. Install the heater core cover using a Phillips screwdriver.
