    That may be an A/C line coming from the condenser in front of the radiator.

    you said you were a "computer guy" -
    I just wondered if you were more knowledgeable with computers than you are cars - -----------------------------------

    OK - forget the petcock - you'll probably end up breaking it -

    just remove the lower radiator hose - and be done with it -

    yes - the big 2" black rubber hose -

    yes - at the lowest point of the radiator -

    yes there is a clamp on it that will have to be loosened -

    yes - it could be a spring clamp - or a worm-gear type -

    no you don't have to remove the clamp altogether -
    just loosen it -

    yes - the hose will have to be GENTLY twisted - and wiggled to remove it -

    Make yourself a removal tool out of a 3/4" piece of dowel rod and cut a slot in the end of it. Mine finally broke. Here is my new improved version, but you get the idea.

    Re: New to Cars in General, have a 95 Eldorado, plethora of problems, help?! D:

    Thank you. In order to do that, I am gonna need the right size wrench / sockets to get the metal plate off, to get the air filter box out. I will get on this.

    Disregard the move of hijack posts. Too intermingled. They'll have to stay.

    ----------

    If you don't have a socket set, may as well buy one now if you plan on doing your own wrenching. That will be the building block of your tool set.

    I saw that, and now it definitely makes sense, it didn't when I first saw it. I'll try to make something similar.

    Awesome, thank you. In order to do this I will have to take out the air filter box, which requires I shift the metal plate right over the washer fluid slightly so it can come all the way out, then I know exactly which hose you're talking about.

    Afterwards, I've read different things, I can just run a hose through the coolant tank and have it all flush out, I can have the engine on and gas it very slightly to force anything else out.

    Here is what I am planning for the next few steps:

    1) Get a wrench / correct sockets, or create a rod.
    2) Drain the coolant, mess around with flushing it all out (Can I just run the hose and expect the tank to drain completely after I shut it off? Or after adding a bit of acceleration)
    3) Fill it up with a 50/50 mix and go to Autozone or Orielly's, get my battery tested and get the correct oil / oil filter change the oil / filter and give it a hard spin around the neighborhood to see if its still overheating.
    4) Eventually (more than likely after getting to and from autoparts store) I will flush the coolant system again and add in the correct antifreeze/distilled water solution (which I keep reading get a 50/50 and mix it with distilled water, but wouldn't that in theory be a 75/25?)

    Then hopefully I'll be set for a while, save some money, fix the breaks, change the sparkplugs, and pull my codes again / clear them, and see if my problems are all fixed and ready to be regularly maintained.


    Edit: Yea, I'm thinking it will have to wait until the 1st when I can buy a set
    Quick Edit: I don't care about the thread jacking posts, ha. Least of my worries, if anything, free bumps to anyone who hasn't seen this thread yet.

    Re: New to Cars in General, have a 95 Eldorado, plethora of problems, help?! D:

    Keep in mind that the lower radiator hose is still half way up the side tank and will leave a lot of coolant still in the radiator ON TOP of the coolant that normally is not removable during a coolant change.

    I will flush the coolant system again and add in the correct antifreeze/distilled water solution (which I keep reading get a 50/50 and mix it with distilled water, but wouldn't that in theory be a 75/25?)
    If you flush with water, yes. You'll throw the mix off. Just drain and refill it. Don't make it harder than need be.

    You are correct, but as stated, it's not absolutely pure, it has been mixed in with the rest of the coolant in the car.


    Btw: It was never really cleared up.

    When I cleaned the purge line, there was definitely some bubbling happening. That continued for a long time, then turned into a stream.
    This is why I want to clean it out and put new stuff in there.

    The whole point behind that was to ask:

    1) Could that have been the sole cause of the car overheating?
    2) What else can I be doing to improve overheating issues?
    IE: Replace the air filter, replace the thermostat, replace ?

    In that case you either have to do some calculations and estimate how much Dex to add to bring it close to 50/50 or use a refractometer.

    Re: New to Cars in General, have a 95 Eldorado, plethora of problems, help?! D:

    Could that have been the sole cause of the car overheating?
    YES - the PURGE LINE being plugged up
    COULD have been the sole cause of overheating -

    there was air trapped in the cooling system -
    and the water pump can't pump against air -
    so that air acted as a dam -
    and prevented the water from circulating through the engine -

    now that the PURGE LINE is cleared - the trapped air was given an escape route -
    and the water pump CAN pump the water throughout the engine -
    and properly cool everything down -

    what I would do to complete this chapter -
    is to flush the cooling system -
    by removing the lower radiator hose -
    stick a garden hose in the serge tank -
    and let it run until you only get water coming out -
    then reinstall the lower radiator hose.

    to get the proper 50/50 mix of water to antifreeze -
    with an unknown amount of water still in the system -
    could be a problem even for a math wizard -

    W + A = PC
    where W = 1/2 PC
    and A = 1/2 PC
    where W = X
    and A = Y
    solve for X and Y
    when PC = 12.5

    but there is an easy answer -

    your cooling system holds EXACTLY 12.5 quarts of fluid -

    to get a 50/50 mix - you need 6.25 quarts of antifreeze -
    let's just call that 1 1/2 gallons - PLUS a splash -
    and the rest should be water -

    so - go out and buy 2 gallons of straight antifreeze -
    NOT the 50/50 pre-mixed stuff -

    add 1 1/2 gallons of antifreeze - then top it off with water -
    the end result - a PERFECT 50/50 mixture -

    YES - everyone says to use a mix of antifreeze and DISTILLED WATER -
    and YES - it is preferable - if possible - but certainly NOT critical -
    it will be just fine with antifreeze and tap water -

    What else can I be doing to improve overheating issues
    replace the thermostat?
    thermostats are so reliable compared to years ago -
    they RARELY fail - I wouldn't bother replacing it at this time -

    IE: Replace the air filter
    ?
    OK - now I am going to "SPANK" you a little -

    what could the AIR FILTER possibly have to do with overheating?

    and do you really want to IMPROVE overheating?
    or PREVENT overheating?

    Haha, you are the best, Basscat.
    I have no idea, so I was asking. I figured that the air filter could get clogged up and make it harder for your engine to breathe, and then cause more heat that way.
    Thank you for the other info, good sir!

    And obviously by improve overheating, would mean improve the condition(s) in which it won't overheat. So prevent, yea, you got it.

    Re: New to Cars in General, have a 95 Eldorado, plethora of problems, help?! D:

    Update(s)!

    I have been doing a couple runs after purge line cleaning!

    The coolant temp stays roughly optimal with only water during hoooooot days.

    I am letting it cool now to take out the air filter box, open cap, pull off lower radiator hose, drain it out, flush it out. I got a nice sized jug of Peak Long Life Antifreeze and I forgot to get my hands on some distilled water, I will prob end up doing that.

    ----

    The reason for the drive today is I wanted to get my battery tested at Autozone, the guys there are completely helpful, just not knowledgeable about what kind of that GM life meter oil I should be using, so I held back on getting new oil for now, I checked my oil and it looks fine, and also it was at a good level. I do notice a couple drippings of oil on the bottom, but that was when I put it on ramps for the first time.

    It turns out I was using a 525 amp battery, turns out the car needs at least a 790, I got an 800. Replaced that and bam, car starts like a dream! On top of that and not overheating (I drove it how I generally did before I knew it overheated, and it never did. The distances I was going I would have overheated 1-3 times prior to cleaning the purge line). I feel like it turns into straight maintenance from here on out.

    However, there is the 'battery tray' issue. I asked what this wire was called that was pointed out to me (going to the battery tray) as having corrosion on the wires. He said I just need to order a new piece and its easy to throw in and replace. So that's good news.

    I just again watn to thank everyone who has helepd out. Turns out there weren't MAAAAANY issues to be had! :O
    So far. Ha.

    You can't tell anything by looking at the oil. Change it when the OLM tells you to. Use 10W30. Brand or type is irrelevant. Whatever tickles your fancy and don't even ask. There is no "best oil".
