    Default 2004 300M overheating problem


    We have changed the thermostat and it is still overheating. We took it
    to the dealership and they put it on the computer and told us it showed
    no problems. Advised us that we probably got a bad thermostat or put it
    in backwards. We got another thermostat and put it in, and are still
    having the same problem. The fans are working, the tank is full of
    coolant, and we cannot find the problem. Any suggestions?

    How many miles?

    Is it losing coolant?

    Did you follow the procedure for purging air out of the system
    when you put the thermostat in?

    Remember that if the system cannot hold pressure the coolant
    will boil - boiling coolant is not very efficient at carrying away heat.
    If it is leaking coolant it isn't going to be holding pressure.

    In addition to what Ted said, there were some instances reported on the
    300M Club of two things (not both on any one vehicle):
    (1) Bad water pump impeller.
    (2) Some casting debris or slag left in the coolant passages blocking
    coolant flow.

    I don't recall if any of these instances were on 04's or not, but I
    would advise a search on their forums
    (http://300mclub.org/forums/index.php...dc347d2afee34),
    as well as posting your situation and seeing if anyone with first-hand
    knowledge of these problems can provide further info.

    As motivation to the dealer to find and resolve the problem, I would
    hint at invoking the lemon law if your state has one - you're still
    under warranty, right?

    Good luck!!

    Is it really overheating, or is it just that the dash gauge shows
    overheating? Have you verified the actual engine temperature with a
    different gauge? It could be a bad gauge sending unit.

    If it really is overheating, have you thorougly bled all the air out of
    the system? Does the heater blow hot air if you turn the heater on full
    blast? It could be entrapped air, or a bad water pump.

    I just had my 04 300 special in the shop for overheating. They went
    through all the same stuff youve been through and it wasnt fixed. They
    ended up pulling the head and there was sand and metal shavings
    clogging it up. They told me it was a common thing from the factory
    defect on the 3.5. After they did that and replaced the head gasket, my
    over heating problems were fixed.

    The "tank" is full of coolant? How about the radiator? Is there air in the
    system?
