    A:
    To remove the front heater core, the air conditioning system must be discharged and the battery cable disconnected. Drain the cooling system and detach the air conditioning lines from the evaporator core fittings at the firewall. The heater hoses should be disconnected from the firewall, and the engine cover, battery, and accumulator removed.
