  • losing antifreeze mix
  • Hey,

    I have a '47 9n that has started using more and more coolant. I bush-hogged (4') for 2+ hours and used up 2.5 quarts...and it still runs and doesn't smoke! There are no bubbles in the coolant when running and there is no evidence of flow viewed from the top. This machine has a loader, so work on the front is going to be tough.

    Do I start with a thermostat and move onto the water pump?

    Thanks,

    Ted

  • Take out the spark plugs.If one looks a lot cleaner than the others water is getting into that cylinder.

  • Last summer, every time I mowed I smelled antifreese. I Thought I had a leak but all I had was a loose fan belt.

  • OK, I'm just putting your comments in my post even though you answered most already -will make any future archive result searches easier to understand. Are you overfilling and causing an overheating condition? If not overheating, how are you verifying the coolant is getting 'lost'? Your '47 2N would have the 2N-8005, 4 PSI pressurized radiator -is that what you have? Do you currently have a thermostat installed? If so, is it installed correctly, in the upper radiator hose, with the pointed end towards the radiator? SEE Tip 25 from Bruce(VA) Also, and I suspect this may be your root cause problem, it is time to pull the radiator as it is plugged up, and get it to your trusty local radiator shop for boiling and restoring. If you have a newer, Cheena made radiator, that could explain a lot as well...

  • If there is no coolant coming out and onto the ground, it is most likely a blown head gasket. Check the exhaust pipe after a couple of minutes running and note if it's just water condensate or if it is antifreeze.

    Nope.

    See tips 24, 25 & 35.

  • Lordy!
    There's a thread right below which ought to put me/it to straights.
    I bet the thermostat is 10 years old.

  • Re: losing antifreeze mix
  • possibly you are overfilling the radiator and it is just pushing the excess out? How full are you filing it?

  • I'm filling the Chinese radiator only to the top of the fins, I figured that out 25 years ago. I can smell boiling AF and that's a new feature. I have an old Dearborn loader (8A) on it which makes this front distributor
    unit really awful to work on. I would guess that I've got to remove it to replace the thermostat.
    It's not squealing like a bad water pump and isn't dribbling, though I haven't idled it on the pavement.
    I saw no AF flow when I started it but I didn't wait for the engine to warm up.
