Car routine maintenance work done four

In fact, routine maintenance work is very simple, summed up: clean, tight, inspection, supplements.

First, clean
Air contains a lot of dust, sand and an acidic substance, is not only easy to be leaked fuel adhesion, baking at a high temperature to form a hard insulation layer easy, so that deterioration of thermal performance parts, and could easily be eroded by electrostatic attraction body paint face to premature fading.
1. Clean the air filter
Steep dirty air filter will hinder fresh air into the cylinder, resulting in Aiki too thick, incomplete combustion, power down, exhaust exceeded. Modern air filter is generally used paper filter, clean the note: do not use water or oil wash, pat method should be used and purging method. Pat pat filter method that end face, so dust off. Purging method which uses compressed air to filter out internal purge air pressure: the force should not exceed 0.3N / Pa
2. Clean the oil filter
Confusion clogged oil filter will impede the flow of lubricating oil, poor engine lubrication, increased wear and even bush-burning and so on. For this reason, should be regularly cleaned or replaced. Usually replaced once every driving 8000km, if the climate is dry. Should be shortened to 5 000km replacement.
3. Clean the battery
Modern cars are generally maintenance-free batteries, first clean the battery top, to avoid inter-pole due to the electrolyte or other impurities caused by a short circuit; secondly to clean the battery terminals to prevent joints caused by poor contact to produce oxides. Vent should be smooth to avoid excessive pressure or temperature within the battery burst leaving hand.

Second, fastening
After clean vehicles, it is necessary for each connection fastening. Because the process of vehicle vibration, bumps, swing and other reasons, will inevitably lead to loose connections, frayed. Therefore, routine maintenance should promptly tightened. Fastening work daily connections directly related to traffic safety, especially important parts steering, braking, transmission, etc., must not be taken lightly.
1, first of all, the engine around each hose connector fastening, anti-leakage of oil.
2. Second, tighten all electrical equipment, wiring and connectors to prevent open circuit, short circuit, grounding, etc. affect the normal operation of electrical equipment.
3, again, the main connecting member fastened checked. Such as generators belts, steering linkage mechanism actuating means coupling point, drivetrain and tires.

Third, check
After connecting fastening, Tony l should check the height and quality of the oil, because of fluid loss at high temperatures will gradually reduce the level of oxidation and lead to poor performance
1. Check the battery fluid level with a 5 N 6mm diameter tube, add liquid from the mouth of the vertical force to filter into contact with the upper end closed with the thumb to live tube, lift tube, measuring the height of the liquid column which is the Battery fluid level, the standard should be 10 N 15mm.
Height 2, check the oil level in the
Remove the oil dipstick cold car, after the wipe into the bottom of the oil pan, after observing its height should be between the upper and lower marking. Hot car should turn off standby all the oil flowing into the oil pan and then measured.
3. Check the coolant level in the height of the cold when the coolant tank should be full, the expansion tank fluid level should be between the markings. Hot car should be slightly higher than the standard liquid level
4, check the brake fluid, steering fluid level height
Unscrew the bolts, direct observation level is within the specified range markings.
5, check the oil quality
Regardless of the oil, can use the following methods to check.
(1) the appearance of law: View the oil sample was taken, and if more transparent, indicating that contamination is not serious; if the mist, the oil in the seepage water; if gray, may be contaminated with lead or other abrasive; if present Black, high-temperature exhaust gas is contaminated.
(2) Diffusion Method: drop of oil samples taken on filter paper, if the proliferation of a wide area and the diffusion region and the oil droplets no significant difference, indicating that the oil cleanliness is good; otherwise it is clean of oil change poor.

Fourth, add
1, oil supplement
If you did not find a significant deterioration of oil, should look into the leaks, check if it should be excluded, and promptly make up the same level of oil.
2, fluid replacement
If oil deterioration or exceed the replacement cycle, should be replaced.
Usually every six months traveling 8000km or replaced once the oil; each driving 20,000 to 4 million km or two years to replace a brake fluid; 1-2 years to replace a coolant; every year or with the use of thousands of meters to replace a hydraulic oil .
