2 Answers
Contents of the third-level maintenance of a vehicle: 1. Disassemble and inspect the engine, check the cylinders, pistons, piston rings, connecting rods, and bearing wear, remove carbon deposits, gum deposits, and cooling system scale, grind the valves and adjust the gaps; 2. Disassemble, clean, inspect, adjust, and troubleshoot the front axle, steering, transmission, drive shaft, rear axle, suspension, and brake assemblies; 3. Inspect the frame and body, remove rust, and touch up paint. Vehicle maintenance refers to the preventive work of regularly inspecting, cleaning, supplying, lubricating, adjusting, or replacing certain parts of the vehicle. The purpose of vehicle maintenance is to keep the vehicle clean, maintain normal technical conditions, eliminate hidden dangers, prevent faults, slow down the deterioration process, and extend the service life.
The third-level vehicle maintenance is a big job, taking a whole day each time. With 15 years of driving experience, I know it well. It includes changing the engine oil and oil filter, checking the wear level of brake discs and pads, testing the transmission system like whether the gearbox oil needs replacement, and adjusting the suspension to prevent bumpy rides. The lighting system requires testing each bulb's voltage, and scanning for electronic fault codes to prevent black screens. During my last maintenance, I found loose wheel bearings and fixed them in time to avoid a tire blowout. The related benefits are safety first, especially ensuring responsive brakes at high speeds, preventing costly roadside breakdowns and towing fees. Spending a little on regular maintenance is better than major engine repairs. It's generally recommended every two years or 20,000 kilometers.
