Replace the "four filter" is the key to car maintenance, "four filter" that is, oil filter, fuel filter, air filter and air filter of the car, they require periodic replacement. They are like the engine of "clean" Guardian is committed to ensure that the car "heart" of the normal operation, minimize wear and tear. Then the "four filter" How to maintain it?

1, oil filter

Oil filter for cleaning the oil, to prevent dirt particles from entering into the oil circuit and therefore the bearing portion. This prevents the engine oil due to solid impurities (e.g. metal wear particles, soot or dust particles) deterioration in advance.

Maintenance Raiders:

Replace the oil filter replaced at the same machine. Otherwise, the dirty oil filter in the oil will be mixed into the newly added among the effects of maintenance effect.

Fully synthetic engine oil change intervals are 10,000 km or 1 year; semi-synthetic oil change intervals are 7,500 km or 6 months; the replacement cycle of the mineral oil is from 5000 km or 3 months.

Check the dipstick (oil plane) per week. Check the color of the oil and thickening, thinning situation.

2, fuel filter

Effect of the fuel filter is to filter the fuel (petrol, diesel) engines needed for combustion, to prevent foreign matter such as dust caused by the fuel, metal powder, moisture and the like entering the engine, causing obstruction to prevent engine wear and fuel supply system.

Maintenance Raiders:

Fuel filter is divided into two kinds of external and internal. External filter generally replaced every 20,000 km; built-in filter probably replaced every 60,000 km.

When maintenance or replacement, non-smoking and use of fire; To use lights, make sure the lights used are consistent with occupational safety standards;

Replace the fuel filter must be carried out in the cold state of the engine, because the high temperature exhaust gas discharged from the heat engine when the engine is possible to ignite the fuel.

3, the air cleaner

In order for the engine to work, there must be a lot of clean air intake. If the engine air is drawn into harmful substances, the cylinder, the piston assembly will increase the burden, abnormal wear condition, leading to deterioration in engine performance, shortened life expectancy.

And the air cleaner can play a role in preventing contaminants from entering the air oil. While further air air cleaner having a silencer function Oh.

Maintenance Raiders:

We recommend traveling 10,000 km per vehicle owners to replace the air filter once. Vehicles often work in harsh environments should not be replaced once over 10,000 km.

To control the 5,000 km cleaning cleaning, be careful not to scrub clean water, use high-pressure air to remove dust.

4, air filter

Air filters mainly filter air entering the interior of the passenger compartment from the outside to improve the cleanliness of the air filter substances generally refers to impurities, fine particles, pollen, bacteria, industrial waste gas and dust contained in the air, and the like.

The effect of air filter is to prevent damage to the air conditioning system such substances, to create a good air environment, protect the health of the owner, there is glass to prevent fogging.

Maintenance Raiders:

Air filter replacement cycle is generally cars 8000-10000 km, can also be set according to the driving of the external environment, if the ambient humidity contrast big, year-round dry climate, large wind, should be replaced in advance.

If the air conditioning blow found to significantly reduce the flow of air, it said air filter may be clogged. Should be considered clean or replace the filter.

I Hint: the replacement of the "four filter" to ensure parts quality! Oil and gasoline grid cell and other accessories have a great influence on the whole condition, so do not be replaced when they are cheap, be sure to choose high-quality accessories.
