Car maintenance tips

What are the common car maintenance items?

1. Main car maintenance items that should be checked after using the car

Check and replenish fuel and lubricants. Clean the interior and exterior of the vehicle as well as the engine and chassis.

Check the horn, lights, and wipers. Check whether the leaf spring is broken and whether the spring lifting lugs and riding bolts are loose. Check the half shaft and tire nut to see if the steel ring is damaged or cracked. Check the tires for cracks and deflation. Especially in winter, you need to perform additional winter car maintenance routine inspections. If antifreeze is not added to the cooling system, the radiator cover, drain switch, and engine drain switch should be opened to drain the cooling water and start the engine for a short period of time to drain the water to avoid remaining frozen cylinders and cracks. Vehicles with radiators and air brakes should drain all the sewage in the air reservoir. After turning off the engine, close the switch and tighten the hand brake, and check the ammeter for leakage.

2. Routine car maintenance items

After the first-level maintenance work is completed, the car should be clean and tidy, the connections should be firm, the three filters should be smooth, and there should be no oil, water, or air leaks. , No leakage.

The cleaning tasks of routine car maintenance include: cleaning and maintaining the air filter. Drain the oil and water accumulation from the air reservoir. Clean the car body and wipe the engine and chassis parts. Clean the fuel filter. Release the sediment in the oil filter, turn the filter handle 3-4 turns, clean the oil filter, and replace the filter element according to the degree of contamination.

Routine automobile maintenance and lubrication work items: Check the oil levels of the engine, transmission, rear axle, and steering gear, and add lubricating oil according to regulations. The oil nozzles of all parts of the vehicle are fully equipped and effective, and grease is added according to regulations (water pump, rotating shaft, universal joint, steering knuckle, steering tie rod, etc.). This part may require a certain understanding of cars, and you can also go to a car 4S store regularly for routine car maintenance.

First-level automobile maintenance inspection and tightening work items: check whether the brake valve and brake pipe are leaking, check the brake fluid level of the hydraulic brake master cylinder, and add brake fluid according to regulations. Check and adjust the clutch pedal, the free travel of the brake pedal, and check whether the brake pedal fixed shaft and cotter pin are intact and reliable. Check and tighten the connections and bolts of all parts of the vehicle. Check the tightness of the steering gear, tie rods, straight tie rods, and steering arm connections. Check and adjust the tightness and fixation of the air compressor, engine and fan belts. Check the tire pressure and inspect the tires for damage. Check the battery shell, clear the vent hole of the small cover, and replenish the electrolyte. Check whether the lights, wiring, and wiper switches are complete and intact. Whether the speaker volume and tone are normal and whether the various instruments work well.

There are many types of regular car maintenance items, but they are basically the same for various models. Moreover, there are many routine car maintenance items that are not easily damaged under normal driving conditions, so they only need to be checked, such as: tire side slip, braking effect and pedal play, handbrake effect, clutch clearance and clutch oil quantity, steering wheel play, air conditioning system, instrument functions, seat belts and warning systems, electric windows, sunroofs, rearview mirrors, lights, wipers, horns, antennas, central locking, battery fluid, air-conditioning compressor belts, power distribution Disk cover and flame distributor, high-voltage wires, ignition timing, idle speed and exhaust gas, power steering system, gasoline pipe, drive shaft dust boot, exhaust pipe muffler, suspension fixing nut (chassis inspection), tires and wheel discs, Wheel bearings, front brake pad pump oil pipe, deceleration secondary air intake system, positive crankcase ventilation system, evaporative exhaust gas control system, intake air temperature control system, coal contact converter and oxygen sensor, etc., the above equipment If there is any damage (abnormality) after inspection, the maintenance shop will replace or adjust it.

For routine maintenance of a new car, the engine oil, oil filter and transmission oil need to be replaced after driving 1,000 kilometers. Because all the parts of the new car are completely new combinations, they are in contact with each other. For example, the friction between the piston and the piston ring, and between the gears in the gearbox will produce fine residues after friction, and these residues will flow into the engine oil and transmission that lubricate the parts. in tank oil.
