It covers draining via the block bolt versus radiator hose, evacuating the recovery tank with low-PSI compressed air, coolant type/dilution notes, the 3.3-quart capacity, refill technique, and bleeding air from the system. Best for owners doing this job themselves.
Posted by the averagejoevideo channel, an owner walking through his own tractor's maintenance step by step, not a dealer or sponsored source.
Drain the block via the drain bolt, evacuate the recovery tank with low-PSI air, refill the radiator to the neck, then fill the recovery tank to the H mark and run the engine to check the level.
The coolant capacity for the BX23S is 3.3 US quarts, which includes the recovery tank.
Yes, any plain green ethylene glycol-based coolant from an automotive or department store should work, as long as you check if it needs diluting with water.
Because air pockets may still be in the system, and filling to H gives the unit a way to recover coolant as needed.
