It is an inspection to determine the technical condition or working ability of an automobile. In the process of automobile use, with the extension of service time (or the increase of mileage), its parts are gradually worn, corroded, deformed and aged, and the lubricating oil deteriorates.

As a result, the clearance of mating pair becomes larger, resulting in looseness, vibration, ringing, air leakage, water leakage and oil leakage, which leads to the decline of automobile technical performance. The core of automobile maintenance operation (or automobile maintenance operation) is to "maintain" the integrity of automobile technology.

Matters needing attention in automobile quality inspection

1, routine maintenance

Oil, machine filter, gearbox oil, brake oil, air filter and air conditioner filter should be replaced or checked.

2. Oil/machine filter

You can consider changing to oil with better fluidity at low temperature. In addition, for vehicles burning engine oil, it is necessary to replenish engine oil in time. If it happens to be a normal maintenance cycle, it is also necessary to clean the oil circuit once.
