Recently, the weather is getting colder, and a cold snap has struck the North. Maintaining the Cummins diesel engine in such cold weather is very important. Here, we briefly introduce some methods to maintain your Cummins diesel engine in winter, which can help ensure its performance and longevity.
Pay close attention to weather changes when leaving the Cummins diesel engine outside after it stops working. If the local temperature drops below 4°C, drain the coolant from the water tank. Water expands as it freezes, which can damage the radiator.
Cold weather increases the demand on both oil and air filters. If the air filter is not replaced on time during winter, it can negatively affect the service life of the Cummins diesel engine.
In winter, the Cummins engine should only be started when it reaches a natural temperature. Due to low cylinder intake temperatures, measures should be taken to raise the engine temperature before starting.
Before running at full load, the Cummins engine should operate at low speed for 3–5 minutes. This helps raise the engine temperature and allows for checking lubrication conditions. Avoid sudden acceleration during operation, as it can reduce the service life of valve components.
During winter, it is recommended to select low-viscosity oil for the Cummins engine. This helps improve lubrication performance and ensures smooth operation in cold temperatures.
