    Warning: On vehicles equipped with airbags, disable the airbag system before attempting any steering wheel, steering column, or instrument panel component diagnosis or service. Disconnect and isolate the battery negative (ground) cable, then wait two minutes for the airbag system capacitor to discharge before performing further diagnosis or service. This is the only sure way to disable the airbag system. Failure to take the proper precautions could result in accidental airbag deployment and possible personal injury or death.
    Warning: Refer to the applicable warnings and cautions for this system before performing the following operation. Failure to follow the warnings and cautions could result in possible personal injury or death.
    Remove the silencer boot fasteners located around the base of the lower steering shaft from the dash panel so that it may be pushed aside.
    Remove the brake lamp switch from its mounting bracket.
    Disconnect the power brake booster input rod (push rod) from the pin on the brake pedal arm.
    If equipped with power adjustable pedals, remove the adjustable pedal assembly.
    Note: Take the proper precautions to protect the carpeting below the heater core from spilled engine coolant and have absorbent toweling readily available to clean up any spills.
    Remove the heater core tubes.
    Remove the two screws that secure the heater core mounting plate to the HVAC air distribution housing.
    If NOT equipped with power adjustable pedals, pull the accelerator pedal upward and push the brake pedal downward for clearance to remove the heater core from the air distribution housing.
    Remove the heater core by carefully pulling it straight out of the side of the air distribution housing.
    Installation
    If NOT equipped with power adjustable pedals, pull the accelerator pedal upward and push the brake pedal downward for clearance to install the heater core into the HVAC air distribution housing.
    Install the heater core by carefully pushing it straight into the side of the air distribution housing.
    Install the two screws that secure the heater core to the air distribution housing. Tighten the screws to 2 Nm ( 17 in lbs ) .
    Install the heater core tubes.
    If equipped with power adjustable pedals, install the adjustable pedal assembly.
    Connect the power brake booster input rod to the pin on the brake pedal arm.
    Install a new brake lamp switch.
    Install the silencer boot around the base of the lower steering shaft on the dash panel.
    Reconnect the negative battery cable.
    If the heater core is being replaced, flush the cooling system.
    Refill the engine cooling system.

    It pays 1.4 hours to replace plus the heater core, thermostat and coolant flush.

    Good luck
