    I need to drain some coolant out of a V40 2002, where is the plug and
    is it clock or anti clock to open, I dont want to break the valve.
    Previous owner has near pure antifreeze and I get little interior
    heat, I checked it with a new Prestone needle gauge. It has so much
    antifreeze it wont even register a %.

    Ok I found and removed some coolant from the valve, I wish this
    radiator had a cap like old ones. Do I just fill the expansion tank
    and it fills the radiator? Do I have to run it while watching it? How
    much coolant do these 4cil hold, filling an expansion tank has me
    worried I now have air in the system.

  3. yep, run the motor and slowly add your coolant via the
    coolant tank....once the level is stable...fill to the indicated
    line in the coolant tank...drive for 30 min, check level...drive
    another hour or so, dbl check level...and you should be all set...

    the air should purge itself after a bit of driving...cooling, warm up,
    etc...
    just keep an eye on the level over the next few days and it should
    become stable...

    I usually squeeze the upper hose a few times once it's warmed up and
    that does a good job of getting the air out. After that just check it
    after a few days of normal driving to make sure everything is ok.

  6. yea, puttin' the squeeze on the hose is a good idea....it keeps
    the coolant moving around and gets the air moving.....

    Antifreeze doesnt transfer heat as well as water, the idiots did have
    pure antifreeze in it, I put in 3 quarts of water in a 6 qt system and
    now my heat comming inside is about 20 degrees hotter.

  8. Don't forget to turn the heater on so the air is purged out of the core of
    the heater .

  9. Theres a red plastic bleed screw on the right hand side of the engine on a
    major water hose ,just let it bleed out of there as well .When my wifes
    conection on the top of the engine to the reserve tank went the way of all
    plastic I used a gauge connecter which was mean't to go in series with the
    hose to allow a gauge to be fitted .Then where the take off line for the
    electrical fitting went in the connector I put a brass fitting allowing
    water to retun to the overflow tank .It will last the life of the car and
    its solid .I hear Japanese like putting pure glycol in as the engine doesn't
    corrode but the temperature would go up as water and glycol 40% water 60%
    glycol is best any higher glycol level lowers the effectiveness of the
    glycol .
    When I lived in Tasmania (down under down under )I found taxis removing
    thermostats and using normal tap water .Come a very cold day and engines
    blew up as the water went through the radiator too fast to cool .An expert
    mechanic there only had to know what a car looked like :~)

    How can a motor blow up from no thermostat, You said it goes through
    to fast to cool, exactly the opposite would happen, the motor just
    takes forever to warm up, I used to run no thermostat in a V8, on a 4
    in winter it just wont get warm, it wont blow up. Japs use pure
    glycol? on every can of antifreeze ive read it saiys dont use pure
    glycol, the motor will run hotter and the trans if the cooler is in
    the radiator
