What are the maintenance methods for Petrol Car accessories?

If the fuel filter, oil filter, air filter, hydraulic oil filter and various filter screens are too dirty, the filtering effect will be poor, too many impurities will enter the oil circuit cylinder, aggravate the wear of the parts, and increase the possibility of failure; if it is seriously blocked, it will also cause the vehicle to not work properly. If the radiator fins, air-cooled Petrol Car engine cylinder block and cylinder head radiator fins, cooler radiator fins and other parts are too dirty, it will cause poor heat dissipation and high temperature. Therefore, for these "afraid of dirt" parts, clean and maintain them in time.

If the temperature of the Petrol Car engine piston is too high, it is easy to overheat and melt and cause cylinder sticking; rubber seals, triangular tapes, tires, etc. are overheated, which is easy to age prematurely, performance degradation, and shortened service life; starters, generators, regulators and other electrical equipment coils are overheated, which are very easy to burn and scrap; vehicle bearings should maintain an appropriate temperature. If they are overheated, the lubricating oil will quickly deteriorate, eventually causing the bearings to burn and the vehicle to be damaged.
Various matching parts in the diesel engine fuel system, the main and driven gears in the main reducer of the drive axle, the hydraulic control valve block and valve stem, the valve core and valve sleeve in the full hydraulic steering gear, etc., these matching parts are specially processed and ground in pairs during manufacturing. The matching is very precise. They are always used in pairs during the service life and must not be interchanged. Some matching parts, such as pistons and cylinder sleeves, bearings and journals, valves and valve seats, connecting rod big head bearing caps and rod bodies, etc., have a relatively good matching after a period of running-in. During maintenance, they should also be assembled in pairs and not "visit" each other.
The cylinder gasket of a Hongqi Car engine cannot be installed upside down, otherwise it will cause premature ablation and damage to the cylinder gasket; some special-shaped piston rings cannot be installed upside down, and they should be assembled according to the requirements of different models; there are also directional requirements for the installation of the fan blades of a Hongqi Car engine. Fans are generally divided into exhaust and suction types, and they cannot be installed upside down, otherwise it will cause poor heat dissipation and excessive temperature of the Hongqi Car engine; for tires with directional patterns, such as herringbone pattern tires, the ground imprint after installation should make the herringbone tip point to the rear to ensure greater driving force. For two tires installed side by side, different models also have different requirements, and they cannot be installed at will.
