How to Service and Repair the Heater Core on 2003 Toyota Land Cruiser?

The serviceable repair of front heater units starts with draining radiator coolant while allowing some coolant to remain. Beginning the heater radiator service requires the use of pliers to carefully release hose clips from their positions on the pipe connections for water hoses. Disconnect the hoses after this step. Installation requires pressing the water hose until it reaches the second ridge on the heater radiator pipe followed by attaching the hose clip according to the designated position. After removing the instrument panel with reinforcement you will need to tackle the front cooling unit then move onto the heater unit by starting with removing the lower defroster nozzle and disconnecting it from its connector followed by the removal of four heater unit securing nuts. The installation process takes place through steps that reverse the steps used during removal.
