Cat excavators should normally maintain their water temperature standards in the range of 80°C-95°C, which is an ideal working temperature range at normal operations.When the water temperature of the Cat excavator exceeds this range, especially when it reaches or exceeds 95°C, it can be considered to be very high.Excessive water temperatures may not only affect the performance and lifetime of excavator engines, but may also cause cooling system malfunctions or other potential problems.In order to ensure that the Cat excavator maintains an appropriate working temperature, regular inspection and replacement of coolant, clean-up of radiators and monitoring of water temperature as indicated in various instruments are essential.At the same time, operators should adapt operating patterns and rest periods to the working environment and load conditions in a timely manner to avoid excessive water temperatures resulting from prolonged high-intensity operations.In summary, for Cat excavators, once the water temperature is found to be close to or above 95°C, it is considered to be in high temperature condition and maintenance is required in a timely manner to ensure the proper functioning and efficiency of the equipment.
