    Yeah.. if you fill it to the top of the filler neck it drools about half a cup of AF on the ground when it heats up to operating temperature. After that it's fine.

    Does the HST have an oil cooler setting in front of the radiator and gear does not? If so, the oil cooler would be adding more heat to the radiator (warmer air coming through the fins) so more expansion room is needed.

    So when it cools down it could suck air in?

    That is how old tractors and cars were made. You just filled them up about half way between the tubes and the top of the radiator.

    The drain on our 1635 is lower than the block, so everything gets drained, cab included.

    There will still be some in the water jackets. The water jackets go lower than the water pump.
