Caterpillar 336D hydraulic excavator experiences high temperature alarm during summer

Caterpillar 336D excavators, like humans, are affected by summer heat waves every year. During the homework process, the temperature of the excavator increases with the outdoor environment temperature, which is a normal phenomenon. When the temperature is high, as long as it is handled properly, it will not cause damage to the excavator. If your excavator suddenly triggers a high temperature alarm during operation, please do not panic. Follow the following steps to effectively reduce the water and oil temperature.

1. "Reduce load, low speed" to minimize heat absorption

Turn off the pilot lock and idle the throttle to first gear to reduce the load and speed. The heat generated by the friction of various moving parts will correspondingly reduce the heat generated by the engine, indirectly reducing the heat absorbed by the coolant and thus reducing the speed of water temperature rise.

2. Increase the air intake of the water tank to accelerate heat dissipation

Open the side doors on both sides of the excavator to increase the airflow entering the radiator, which can quickly dissipate the cabin temperature and reduce the rate of water temperature rise.

3. After the temperature drops, check if there is a shortage of antifreeze in the water tank and add antifreeze

If there is no spare antifreeze around, you can add "pure water or distilled water for human use". Do not add river water or groundwater. Here, it is recommended to use the professional antifreeze specified by Caterpillar excavator. It is forbidden to mix antifreeze from different manufacturers or brands.

4. After the temperature drops, clean the radiator

After the temperature drops, check if there is too much dust between the radiator, condenser, and water tank, and thoroughly clean them with high-pressure air to ensure good heat dissipation performance of the water tank and condenser. Usually, attention should also be paid to wiping the dust between the condenser and the water tank. In fact, 80% of high temperatures in excavators are caused by poor heat dissipation. https://www.lh-usedexcavator.com  Therefore, thoroughly cleaning the surface debris and internal scale and oil stains of the radiator is the ultimate solution to solve the high temperature problem of excavators
