The fourth maintenance includes the following two categories: Replacement: Replace engine oil, oil filter, air filter, cabin air filter, spark plugs, brake fluid, and power steering fluid. Inspection: Check the tire pressure of the car, inspect the tires for any damage, and examine the car's battery, lights, wiring, and various instruments. Below are some precautions for car maintenance: Choose a reputable maintenance shop: Only reputable maintenance shops follow strict maintenance procedures, while some non-standard shops lack strict procedural requirements. When getting your car serviced, it is advisable to choose a reputable maintenance shop, as such shops are relatively more transparent in terms of service quality and pricing. Additional items: During the car maintenance process, the choice of additional items is up to the car owner. Owners can decide whether to opt for additional services based on their usual driving habits and the explanations provided by the staff.

The fourth maintenance is considered a mid-term service. I generally recommend focusing on these key tasks: definitely replace the engine oil and oil filter, and the air filter should basically be renewed as well. Checking the brake pad thickness and tire wear is particularly important, especially after driving 10,000 to 20,000 kilometers. If the manufacturer's manual specifies changing the transmission fluid every two years, go ahead and schedule that. The mechanic will also inspect whether the chassis bolts are loose and if the brake fluid's moisture content exceeds the standard. With summer approaching, I took the opportunity to replace the cabin air filter too, and the airflow feels much fresher now. Remember to ask the mechanic to scan for trouble codes with the computer—modern cars have many electronic components, so a thorough check provides extra peace of mind. After the maintenance, the engine noticeably runs smoother. Don’t skimp on necessary expenses—safety always comes first.

Just had the 40,000 km service last week, cost over 800 yuan mainly for these: mandatory oil and filter change. The mechanic tested battery life showing 70% remaining. Focused on brake pads - thickness was fine but removed rust from rotors. Rotated tires, tread depth still good from mostly city driving. Topped up coolant and cleaned sunroof drainage holes. Service sheet noted handbrake tension adjustment. I separately replaced cabin air filter - AC now odor-free. Manual required transmission fluid inspection but didn't change yet, will wait until 60,000 km. Remember to bring your manual, service items vary significantly by model.

The specific items for the 4th maintenance depend on the actual condition of the vehicle, but the core items mainly consist of three parts: First, for the engine, the engine oil and oil filter must be replaced, and the air filter should be cleaned or replaced. For the transmission system, check the transmission fluid; manual transmission vehicles typically require a replacement. Key chassis items include tire rotation and balancing, brake pad inspection, and exhaust pipe hanger reinforcement. For the electronic system, it's safest to have the shop perform a full vehicle scan with a computer. I additionally had the throttle body cleaned, and the throttle response noticeably improved. Remember to bring the last maintenance record for comparison to ensure no items are missed. Many shops offer free windshield washer fluid top-ups—don't forget to take advantage of that.
