The low temperature environment in winter poses a special challenge to the working performance of the oil filter assembly. Low temperature can cause an increase in oil viscosity, a decrease in fluidity, and exacerbate problems such as seal hardening and filter blockage. If targeted maintenance is not done properly, it can easily cause assembly failure and affect the safety of engine cold start. Mastering the key points of winter use can effectively improve the adaptability of the assembly and ensure the normal operation of the vehicle in winter.

The increase in oil viscosity at low temperatures will increase the resistance to oil circulation. If the opening pressure of the assembly bypass valve is not set properly, it is easy to cause poor oil circulation, resulting in insufficient lubrication during engine cold start. Therefore, in winter, an assembly suitable for low-temperature conditions should be selected, and the bypass valve opening pressure should be optimized to open in a timely manner when the oil is viscous, ensuring oil circulation. At the same time, the filter element should have good low-temperature anti clogging ability.

Seals are prone to hardening and becoming brittle in low temperature environments, leading to a decrease in sealing performance and an increased risk of oil leakage. Before winter use, check the condition of the assembly seals. If the seals are found to be hard or cracked, replace them in a timely manner; Ensure that the sealing components are tightly attached to the interface during installation, and replace the sealing ring with a new one if necessary to avoid malfunctions caused by sealing failure at low temperatures.

In addition, it is necessary to shorten the assembly replacement cycle appropriately in winter. Under low temperature conditions, the engine's cold start wear intensifies, resulting in increased impurities and poor oil flow, which accelerates the clogging speed of the filter element. At the same time, when changing the oil, choose a model that is suitable for low temperatures, reduce the viscosity of the oil, reduce the workload of the assembly, and enable the assembly and oil to work together to cope with low temperature challenges, ensuring the safe operation of the engine in winter.
