If the oil temperature of a photovoltaic crawler pile driver is too high during use, it should be resolved promptly to avoid damaging the machine. First, we must analyze the reasons for the high oil temperature.

1. The cooling fan is unable to rotate, leading to a failure in heat dissipation and an increase in oil temperature. The cooling fan is controlled by a temperature control switch. We can check to see if the problem lies here.

2. The oil temperature is too high due to insufficient cooling medium. Every vehicle needs antifreeze, especially in winter, pay more attention to adding antifreeze to keep it within a reasonable range, ensure the quality of the engine oil, and choose the appropriate antifreeze; water or distilled water is also a cooling medium. At the same time, check if it is sufficient; if the radiator cap leaks, the machine should be promptly found and resolved.

3. The fuel tank is clogged, leading to an increase in oil temperature. The fuel tank needs to be cleaned regularly. If there is an external blockage, it can be flushed with water or air to remove debris. If there is an internal blockage, it will affect the circulation of the coolant, leading to a leaking radiator or increased water temperature.

4. Cylinder damage, the combustion chamber is flushed by the water channel. At this time, the drain pipe will drain or emit white smoke, causing frequent water shortages in the radiator; the water channel and the water passage will be flushed, leading to poor cylinder cooling, especially at high speeds.
