    1953 NAA Overheating?

    Thanks for the tips. I replaced the thermostat last year. It was the original and did not work when I bought the tractor. I worked the tractor regardless sometimes working it until it boiled over which did not happen often. Always checked fluid levels before starting. Before installing...

    Got her back to barn. Put the thermostat in it, added 50/50 antifreeze. It took 2 gallons. Started it, let it warm up. When the temp gauge approached 190 it dropped to 160. I was able to put a 3rd gallon into her minus a quart. Let her run revved it up a couple of times while running the...

Then flushed through upper radiator hose. Did that back and forth. Got spurts of black stuff mostly through block drain...

    1953 NAA Overheating?

    You are right. I made a screen that I fasten onto the grill. It is made from dog proof screening and is very tough. Not only will it catch seeds, branches will not puncture it. It certainly helps in that regard. The down side is like all screens, it restricts air flow. Last week while...

    When my gauge registers 240 my coolant is boiling and the radiator cap starts to release coolant. I feel the gauge and radiator cap are working. I will flush the engine and then assure my timing is correct. I will post my results. Thanks!

    1953 NAA Overheating?

    Good advice! Thanks. Opened the block drain for the first time since I owned my tractor. Took some prodding and air pressure and got the block to drain and then the radiator. Easily got 12 plus quarts.Things are not as bad as I thought!

    1953 NAA Overheating?

    My NAA always overheated when using my 5ft rotary cutter during the summertime. I could cut for an hour, then let it cool down while I cleaned the radiator. Now it is taking half that time. I had the rotary cutter gear box rebuilt and the blade sharpened this past winter. Just recently replaced...
