How Often Should Secondary Vehicle Maintenance Be Performed?

The transportation management regulations stipulate that secondary maintenance for trucks must be performed every three months, and maintenance recordings must be made at repair shops. Below is relevant information about secondary maintenance: 1. Secondary Vehicle Maintenance Item One: Engine; Secondary vehicle maintenance requires checking the engine's condition during idle, medium, and high-speed operation, as well as whether cylinder pressure and vacuum levels meet standards. It also involves verifying if the engine's various indicators after the 'three cleans and three filters' operation comply with specifications. This inspection is more detailed compared to primary maintenance. 2. Secondary Vehicle Maintenance Item Two: Clutch; This item involves testing the ease of operation, smoothness, and reliability of the clutch to ensure it is convenient to use, free of abnormalities, and that the hydraulic system has no oil leaks. This helps drivers operate the clutch more effectively. 3. Secondary Vehicle Maintenance Item Three: Tires; Check whether the tire pressure is normal, whether there are debris like small stones in the tire tread that could damage the tires, and whether there are signs of aging or bulging. Additionally, inspect whether the tires rub against the vehicle's floor during normal operation.

My car has been running for over eight years, and I always stick to getting a secondary maintenance every 15,000 to 18,000 kilometers. This stuff is pretty important, including oil changes, brake system checks, chassis suspension inspections, and so on. Regular maintenance like this makes the car run much smoother and reduces the failure rate. Don't think delaying saves money—I've seen my neighbor Lao Wang wait until 25,000 kilometers, and his battery and transmission both broke down, costing him thousands in repairs. So, regular maintenance not only keeps the vehicle in good shape but also extends its lifespan, saving you the hassle of waiting in line for repairs.

Having worked in the workshop for so many years, I recommend that secondary maintenance should be performed every 20,000 kilometers or once a year. The key points are checking the transmission fluid, cooling system, and tire wear. Many car owners delay it for convenience, but faster part wear leads to higher costs, such as engine overheating issues. Maintaining fixed intervals ensures more reliable vehicle operation and keeps repair expenses under control.

Secondary maintenance is crucial for driving safety. I perform it every 15,000 kilometers, focusing on inspecting the braking and steering systems. Extending the maintenance interval can easily lead to accidents, such as brake failure on highways. Timely inspections can protect both yourself and others, spending a small amount to prevent major risks.
