Will my SL2 overheat on a long drive across states?

    Hi there

    This may sound like a stupid question for some of you, but I've noticed
    that my 1995 Saturn SL2 overheats quite readily, and on a hot day will
    'shut off' until it cools down.

    I am wanting to drive from Vancouver, BC to Seattle, Washington, about a
    2 hour drive on the I-5 highway. Do I need to fear the car 'breaking
    down' because of over heating?

    Yes, you should fear that, but not specifically on the highway. Driving
    at 70 mph, your engine should be cooler than it would be driving around
    town at 30 mph. This is due to increased air flow at high speed. But
    your problem is definitely not normal, and you need to get it repaired.
    Unless you like taking a break every now and then to let your car cool

    Does your Saturn still have the air dam? If it's gone, that will cause your
    car to run hot.

  4. Have you checked the condition of your antifreeze & level on the overfill
    tank. Does is still look green or is it staring to take on a coffee colour
    (if it does it is a good sign of a cracked head). You could try flushing the
    rad and install new antifreeze to start with. After you turn the car on see
    if you have a good flow of the coolant after the thermostat opens. Feel the
    top of the rad and compare it to the bottom to see if it is cooler. Does the
    fan eventually come on as the coolant gets warmer (if it doesn't check your
    temperature sensor)? At this point either the cooling system is working
    properly or you should have a found the reason why your car is overheating.

    First it's not green, it's orange. Second, the orange stuff when it's time
    to do a flush, turn brown and kinda thick and slushy.
    Also a note, you car isn't overheating, when a car overheats, stuff breaks.
    It's normal for the temp gauge to go farily close to 3/4 the way to the
    red.I've drivien 6 hours before, never went over 1/2 way, Inface my fan
    usally kicks on around 1/2 way when sitting in traffic. You can alos open
    your windows and turn your heat on full blast this uses your heater core as
    a second radiotor kinda.
    Now if your fan never comes on, and you see steam coming from under the
    hood, check your fan, thermosate and do a flush, replace your thermostate,
    and temp sensors when you do a flush

    Good Luck

    I've had my saturn overheat before because of a bad radiator cap. IIRC,
    this has happened twice. Just replaced the cap and good to go again.

    On a 1995 model, which he said he has, the coolant was green.
