Instructions for Replacing the Internal Heater Radiator

Model: Jeep Grand Cherokee MK 2, WJ - Years 1998-2004
Part: Air conditioning

To replace the heater radiator, you need good general mechanical knowledge and, above all, a lot of patience, as it will be necessary to dismantle almost all the interior components of the vehicle, including the dashboard. This operation is not straightforward, as there are many elements to remove in order to access the radiator and replace it with a new one. Additionally, you must discharge the vehicle's cooling system before disconnecting the inlet and outlet hoses attached to the internal radiator.
