    The heater housing assembly must be removed in order to get access the blower motor.

    1. Drain about two quarts of coolant.

    When draining coolant, keep in mind that cats and dogs are attracted by ethylene glycol antifreeze, and are quite likely to drink any that is left in an uncovered container or in puddles on the ground. This will prove fatal in sufficient quantity. Always drain the coolant into a sealable container. Coolant should be reused unless it is contaminated or several years old.

    1. Remove the heater housing assembly as outlined earlier in this section.
    3. Remove the attaching screws and remove the blower motor.

    To install:
    1. Install the blower motor into the housing, then tighten the attaching screws and nuts.
    3. Install the heater housing as outlined earlier.
