    2007 Chevy Equinox
    3.4L V6
    2WD
    200k miles

    Symptoms:

    • Car overheats when stopped/idling
    • Dual radiator fans work and do turn on automatically.
    • Heater blows cold air when idling

    .
    Things i’ve tried:

    • Replaced Thermostat
    • Replaced water pump
    • flushed cooling system
    • bled air out of cooling system
    • pressure tested to 15psi, stayed at pressure for 5 minutes.

    Any ideas on what could be causing it? Thanks!

    If your getting cold air with the heat on you either have a blockage or air entrapment.
    First see if the heater core is blocked by flushing it out.

    Then bleed the cooling system:

    If it is a troublesome system you may need to vacuum fill the system:

    Thanks for your response. The heater core being blocked won’t cause the engine to overheat though will it?

    If there is a blockage in the heater core, it could be there is a blockage with in the radiator also.
    The two share the same basic design.
