Tedd – Even if a tractor sits outside in a damp climate most of that condensation comes from the engine running too cold. Unless each time it is started the engine coolant (and oil…) is allowed to warm up to 160 – 180 deg so it is vaporized and expelled out the crankcase breather, condensation will gradually accumulate. A few fixes: If the thermostat is broken or missing, replace it! In cold weather use a winter front (or a piece of cardboard, old seed bag, etc) to block 80% - 90% of the radiator opening. Minimize “short runs”. Whenever possible after a cold startup, work the engine a few minutes once it reaches normal operating temperature. Minimize idling – especially in cold weather. If you can’t do the above, used a good detergent oil and change it frequently. Good oil will keep a small amount of condensation in suspension. The condensation is then removed each time the oil is changed. Liquid water and sludge appearing inside the engine says the oil has become saturated with condensation and should be changed more often.
