  • what I learned about antifreeze
  • Recently I had to have a radiator recored for a jd 332. I went to a place a few towns over for the first time, woodstock radiator. Al (ct) might be familiar with the gentleman. He informed me that the white calcium like substance that was choking my rad was the result of lack of maintenance. I protested that this was an outdoor machine and that I checked the freeze point every fall and added antifreeze accordingly. He said that although I was checking freeze point I had neglected to check PH. If the ph becomes acidic it will rot out you rad or in a car your heater core. If the ph becomes alkaline as in my case it will form that white rock hard substance and chokes off the rad. I protested that I Have been doing this for 30 years and never had this problem before. He added that there is a chemical in antifreeze that prolongs its life and this chemical is also used in the denim industry in the making stonewashed blue jeans. Because the two industries competed for this particular chemical the price rose so far that the antifreeze companies started using something else that did not work nearly as well. So I should be checking ph and as soon as falls below or above 7.5 or 8 it should be replaced. He advised those little test strips that can be found on ebay for cheap. I finally asked him approx how often I should be changing my antifreeze. drumroll please,,,,, his answer,,,,,every year. I went home and ordered four packs of those little ph strips. sure enough every machine I own is overdue for antifreeze changing. go figure

  • The original 9N Operator's Manual specifies to only use 'soft water' or rain water in the cooling system. Well water, of which many farmers only had, contains vast amounts of minerals and compounds that will affect operation. When the water boils and cools, it can leave mineral deposits like calcium and iron deposits in the system. It was recommend back then to drain the radiator and the block if temps were to drop down below freezing overnight. Original Ford systems used an alcohol mix. Anti-Freeze came along and eliminated this practice. In these N's it is best to use a 50/50 mix of distilled water and antifreeze. Avoid using the pre-mixed stuff with water in it already. There is plenty of chatter in the archives on this topic as well. As an N-Owner and Operator, one should perform a basic checklist of things before firing up the tractor for use. Checking ALL the fluids is foremost. The engine is cold and fluids have settled since the last time they were used. Likewise the radiator is also cold and you can remove the cap and visually check the coolant level and condition.

  • Though the freeze protection properties of so-called "permanent anti-freeze" last indefinitely, the corrosion protection properties do not. Correspondingly, coolant should be changed every two years or so, depending upon conditions/usage.

    Additionally, as Tim mentioned, it is important to get all of the old coolant out when changing. Simply opening the radiator drain cock will usually drain only about 1/2 of the coolant. If your engine has a block drain (most do not these days) you should open it as well.

    Once the old coolant has been removed, you can flush with clean water and re-drain. Do not use commercial radiator flush chemicals unless you want to replace your water pump within a short while.

    When refilling, refill with new, concentrated anti-freeze and distilled water. I avoid premixed anti-freeze because I have not found any that say that distilled water rather than tap water is used in the mix.

  • Re: what I learned about antifreeze
  • Are you flushing the entire system or just draining old ant-freeze and replacing with new? The PH factor may or may not be true but know too that salesmen will say anything to get you to buy their product. Charles Sorenson, Ford's RH man adviser for forty years, despised Harry Ferguson and once said, "...had I foreseen the consequences of that meeting [with Ferguson] I would have avoided it!" Sorenson also said, "Harry Ferguson could sell you the birds off the trees". Sorenson's opinion of Ferguson was that he wasn't schooled in engineering, but was simply a shrewd businessman. Ferguson held patents on the 9N tractor, foremost was the 3-PT Draft Control System in his name despite the fact that he was not the inventor. The 3-PT Draft Control Hydraulic System was the invention of Ferguson's real engineers, Archie Greer, Willie Sands, and John Chambers. Ferguson merely applied for the patent (and several other 9N parts)on the draft control system because Henry Ford didn't believe in patents and despised lawyers even more ever since his lawsuit (which Ford won) regarding the Selmer Patent over his Model T automobile. FORD engineers designed much of the 9N tractor and the patents went to Ferguson despite this.

  • I usually do mine every two years and stay away from "lifetime" antifreeze in any vehicle other than OEM.
    Like you found out, those PH strips do come in handy.

    Next week will be why 1971 to about 1990 vehicles with auto trans require trans service every 30K and why newer cars, once again, do not.
