  • Re: Pontiac Grand Prix Water Leak

    @thumper14 says, " the tube was flushed."

    What tube do you mean?

    Let's do some "if's":

    With the engine warm and the front of the car uphill on a driveway if possible, run the engine at 2500 rpm for 10 seconds or so, then idle, then repeat 4 more times. This will help move air from the heater core if it has been trapped there. Usually high engine rpms on the road will burp that air out, but maybe not in your case.

    Feel the upper radiator hose after the car has been idling for 15 minutes or driven. It should be so hot you can't hold it barehanded. If it's not warm, let the car sit for hours. Then restart and keep feeling the upper radiator hose for hot water to start through it gradually. The thermostat might be opening too soon in that case. There should be almost no heating of the middle of that hose until all of a sudden the thermostat opens and the engine has reached 195 deg. F.

    If the car is warm after driving for 15 minutes or more and the blower on the heater on low, feel both tubes to the heater core near the firewall.
    Be careful of the moving belts and any loose clothing. Both should be very warm

    If both are warm, turn the blower on high and wait a minute or two and feel again. The one tube should be cooler than the other but still warm. That's the return tube. The air flow through the heater takes heat from the water so the returning water is cool but not cold. You can have someone idle the engine at about 1500 and recheck.

    If one is essentially cool and the other is warm, you likely have a clogged heater core with no flow.

    If the system had DexCool in it that had been contaminated with other coolants when you started having these problem, the core may be clogged by that. If the car didn't have good maintenance, the DexCool may just have coagulated and clogged it. A reverse flush on the heater core may help open it some, and it may easily clog again.

    A few may be able to use some cleaning chemical that will open it, but don't bet the bank on that. The typical flush the garages like to do to clear the radiator usually don't work on the heater core in these.

    Replacement of heater core may be needed.

    70th? Wow, my count was 24 oil & filter changes on the Quest at 200,0

    I might. Have exaggerated a little. LOL
    I DO OIL changes myself. Maybe every 4000.

    There used to be an "Inconsiderate Driver's" tell your stories etc thread. I can't find it, can anyone point me to it, if there still is one?

    Just finished a good book, Killing Reagan by Bill O'Reilly. Thorough, containing
    good and bad. I had enjoyed Killing Patton when I read it earlier. The book
    mentions Alzheimers a lot.

    I believe someone asked about symptoms of Alzheimers in this topic. The
    epilogue mentions that. As far as vocabulary, there may be 3 early hints to the sharp
    readers or listeners. First, is use of repetitive words. Second, increased
    substitution of pronouns instead of specific nouns, such as "it" or "thing."
    And third, use of unique words declines. These were observed by analyzing
    Reagan and his use of words in press conferences looking for early signs.
    Also anesthetics can increase risk of Alzheimers.

    Several weeks ago I was at lunch by myself at ChickFilA. I observed a worn out
    appearing gentleman in his 70s assisting a woman across the traffic lanes from the parking.
    She appeared to be an age to be his wife. He seated her in a booth near the cash registers.
    He then approached the end register ahead of a line of 6 people and I was first in line.
    He walked up to the cashier to place his order, jumping the line. She had looked at me,
    but when he moved in she winked. I am on a first name basis with most of the cashiers and managers.
    We both saw he was frazzled and in poor health; the lady he assisted in
    looked to be in great condition, physically.

    Later I walked by where they were sitting and he was entertaining her playing
    a repetitive hand game much like one would with a child in younger years, and
    she was laughing. I'm certain she was typical of the Alzheimers patients and
    he was the caregiver who was endangering his health taking care of her. So sad.
