The added amount of the Cat excavator is a key point that needs to be precisely captured when refrigerated fluids are replaced.First, it is clear that different Cat excavator models may have different cooling system capacity and therefore the amount of anti-frozen fluid to be added will vary.For example, in the case of Cat320D excavators, the total capacity of their anti-frozen fluids is usually around 20 litres, but the specific additions need to be based on the actual situation and the guidance in the operating manual.In placing anti-frozen fluids on the Cat excavator, it is important to ensure that there are no excesses or deficiencies that adversely affect the cooling system performance of machines.For accurate measurement, after the discharge of the old anti-frozen fluid and the cleaning of the system, new anti-frozen fluids should be mixed with pure water at the prescribed rate and then slowly injected until the maximum tic line specified by the equipment is reached.In summary, to determine how many litres of anti-frozen fluid should be added to the Cat excavator, it must be determined by reference to the operational manual of the corresponding model and taking into account actual working conditions to ensure the proper functioning of the engineering machinery and the efficient use of the anti-frozen fluid.In addition, it is recommended that anti-frozen fluids be inspected and replaced on a regular basis in order to maintain the optimal working condition of the excavator cooling system and to extend its useful life.Knowledge of the basics of anti-frozen fluid addition in Cat excavators will not only help us maintain the equipment scientifically rationally, but also optimize the overall performance of the equipment through sound anti-frozen management.In summary, attention to the correct addition of anti-frozen fluids to the Cat excavator is an important element that cannot be ignored by every owner and operator, and it is important to ensure precision measurement and timely replenishment and replacement in order to guarantee the steady performance of the excavator at various ambient temperatures.
