What maintenance does a private car need at six years?

[WillowLynn]

Private cars at six years require the following maintenance: inspect the timing belt, check all vehicle fluids, transmission fluid, brake fluid, spark plugs, and assess whether tires need replacement. Finally, check for engine carbon buildup to determine if throttle body and fuel injector cleaning is needed. Below is an expanded explanation: All vehicle fluids require inspection: fully synthetic engine oil should be changed every 10,000 km, semi-synthetic every 7,500 km, and mineral oil every 5,000 km. Additionally, as the vehicle ages, cold starts cause some engine wear and reduced cylinder sealing. It may be appropriate to select a slightly higher viscosity engine oil.

My car just turned six years old, so I focused on checking the brake fluid condition since this stuff has an expiration date, and hydraulic fluid failure directly affects braking performance. The coolant was also replaced with new fluid to prevent radiator corrosion. Tire wear was more severe than expected, so all four tires were replaced to ensure wet-weather traction. Consumables like belts and spark plugs were replaced according to the manual, and cracked engine mount bushings were addressed. Finally, I had the mechanic perform a full electrical system inspection, especially on aging wire harness connectors. A six-year-old car is like middle-aged humans – spending extra on comprehensive checks is absolutely worthwhile.

Six-year vehicle maintenance focuses on five key points: First, inspect and replace all vehicle fluids including engine oil, brake fluid, and coolant. Second, check the chassis condition, especially the shock absorbers, rubber bushings, and aging rubber components. Third, thoroughly examine tires to see if wear indicators have reached the limit. Fourth, inspect the ignition coil, spark plugs, and ignition system to ensure fuel efficiency. Fifth, replace both the cabin air filter and engine air filter, and clean the AC evaporator box. I've seen too many six-year-old cars in repair shops turn major issues due to accumulated minor problems. Pay special attention to engine carbon deposit cleaning and exhaust emission testing.

Both of our family cars have passed the six-year maintenance milestone, and I recommend paying special attention to rubber component aging issues. Door seals and window guide channels can harden and crack, while wiper blades need replacement to maintain clear visibility. Check engine compartment hoses by squeezing them to assess if they've become brittle. Brake hoses are most easily overlooked - bulging or swelling poses serious risks. Worn suspension bushings can cause unusual noises, and loose steering ball joints require adjustment. Spending a few hundred yuan replacing these small parts can significantly improve driving refinement.
