Gurgling sound on a Breeze

    My '98 Plymouth Breeze makes this gurgling sound after I park the car
    and turn off the ignition. I opened up the hood one time recently when
    my car was making that gurgling sound and I discovered that the sound is
    coming from fluid that is flowing into the radiator's plastic tank. The
    fluid is fairly clear though, no signs of rust. This gurgling sound is
    quite noticeable. I can hear it in the car with the doors closed. I am
    not sure, but I don't think the sound lasts too long.

    My car has nearly 90,000 miles on it and I am good about having
    maintenance done on it. This has been happening for the past few months.
    I just took a two hour drive in this car and it ran great, but it
    gurgled quite a bit at a rest stop and also, when I finally got home.

    Is this sound a source for concern?

    Thanks,

    Shawn

    Yes. When I've heard gurgling noises like that, they've been because
    air is getting into the cooling system.... anything from a bad
    radiator cap (try that first, on the grounds that it's the easiest
    fix) to a cracked cylinder head.

    That makes no sense at all...... when you turn the engine off and pressure
    in the system is above the limit that the caps specs are (normally
    13-16psi) this noise will occur to relieve the pressure and overflow to the
    recovery tank..
    A cracked cylinder head or blown head gasket would cause a overheating/loss
    of coolant condition before a gurgling noise. And wouldnt a bad cap cause
    loss of coolant before it would cause air to get into the system???

    I've very seldom heard this from inside the car (though you're right,
    sometimes it is audible). When I've heard the gurgling when I wasn't
    actively listening for it, it's been from areas like inside the heater
    core.

    There's enough excess capacity in the system that you can have some
    air in the system before you start overheating.

    I've had "one-way" cooling system leaks twice; once from a head gasket
    and once from a cracked head. Pressure caused overflow into the
    overflow tank as expected, but when the engine cooled down and a
    vacuum formed in the cooling system, it pulled in air through the leak
    instead of from the overflow tank.

    Yes but if you are getting pressure into the cooling system by means of the
    combustion system you will be raising the engine temp. I forget how many
    degrees the temp raises for each PSI.

    Just curious but when you experienced those two problems didnt you notice
    the temperature gauge rising?

    Actually, it makes perfect sense. As long as the engine is running,
    coolant is flowing. When you shut the engine off, the heat soaked into
    the cylinder heads gets transferred to the (now stagnant) coolant in the
    heads and the local coolant temperature skyrockets. If the radiator cap
    isn't strong enough to maintain pressure, the coolant in the heads will
    boil and you get a gurgling noise and coolant puking into the recovery
    tank (or onto the ground in non-recovery systems). I've seen that on
    cars made from 1949 until the present, so its nothing new or unusual at all.

    hmm. I think that is what I said?

    We're talking slow leaks here -- and as you pointed out, the radiator
    cap doesn't let the pressure actually rise. Besides which, I'm
    drawing a complete blank on how increasing the pressure in the coolant
    system could raise the temperature -- the thermostat and the engine
    fans aren't sensitive to the pressure. If it were a thermodynamically
    closed system then raising pressure would raise temperature (ideal gas
    law), but of course it isn't -- that's its whole point.

    Not immediately. There was several weeks between the sound starting
    and my temp starting to climb.

    Since your Breeze is a 1998, and most likely has the 2.0 or 2.4 engine,
    it would not hurt to have the head gasket checked. There is a known
    problem with the gasket on this model. When mine started to leak, oil
    would drip from the left rear corner of the head.
