6, afraid of "oil"

The paper filter element of the engine dry air filter has strong hygroscopicity. If it is stained with oil, it is easy to suck the mixed gas with higher concentration into the cylinder, resulting in insufficient air volume, increased fuel consumption, and reduced engine power. The diesel engine may also cause "A flying car". If the triangle tape is stained with oil, it will accelerate its corrosion and aging, and at the same time it is prone to slip, resulting in a decrease in transmission efficiency, if it is stained with oil, it is easy to slip and work poorly, which threatens driving safety: the starter motor and generator carbon brushes are stained with oil, which will cause insufficient starter motor power and low generator voltage due to poor contact. Tire rubber is very sensitive to oil corrosion, contact with oil will make the rubber soft or peeling, short-term contact will cause abnormal damage to the tire or even serious damage.

7, afraid of "wash"

Some people who are beginning to drive or learn to repair may think that all spare parts need to be cleaned. In fact, this understanding is one-sided. For the paper air filter element of the engine, when removing the dust on it, it cannot be cleaned with any oil. Just lightly pat it with your hand or blow high-pressure air from the inside of the filter element: for leather parts, it is also not suitable. Clean with oil, just wipe it with a clean cloth.

8, afraid of "pressure"

If the tire casing is stored under pressure for a long time and is not turned over in time, it will be deformed due to extrusion, which will affect the service life: if the paper filter element of the air filter and fuel filter is squeezed, it will produce a larger Deformation and cannot reliably filter: rubber oil seals, triangle tapes, oil pipes, etc. cannot be squeezed, otherwise they will also be deformed, affecting normal use.

9, fear of "near fire"

Tires, triangle tape, cylinder liner water blocking ring, rubber oil seal and other rubber products, if close to the fire source, will be prone to aging deterioration or damage, on the other hand, may also cause fire accidents. Especially for some diesel cars, it is difficult to start in winter. Some drivers often use blowtorch heating, so they must prevent burning out the lines and oil circuits.

Fear of "repetition"

Some parts should be used once, but individual drivers or repairmen reuse them in order to save or because they do not understand the "taboo", which can easily lead to accidents. Generally speaking, after the engine connecting rod bolts, nuts, fixed bolts of imported diesel engine fuel injectors, cylinder liner water blocking rings, sealing copper gaskets, various oil seals and sealing rings of hydraulic systems, as well as pins and split pins of important parts, new products must be replaced: for the engine cylinder head gasket, although no damage is found during maintenance, new products are also replaced, because the old products have poor elasticity, poor sealing, easy ablation and damage, and need to be replaced after a short use, it is time-consuming and laborious, so if there is a new product, it is better to replace it as much as possible.
