Are vital parts of a car engine, the usual checks and maintenance should be cautious, externally available cleaning agent to clean the engine, as it will produce carbon interior, impurities, gum and other waste in the work, if the engine more familiar with, you can open washing machine lid can also be used to avoid demolition washing machine without cleaning the internal disintegration, internal fault should be given to the repair shop.
5 Replace the three filter
Three filter is the air filter, oil filter and fuel filter for decontamination kept clean, so clean in time will help to improve the working environment inside the car body.

6. Cooling system inspection and maintenance
Tank: Check tank water reserve tank just look at whether you can limit the room.
7 Thermostat inspection and maintenance
Thermostat failure will cause the engine to heat up slower, low speed when the temperature is low, this phenomenon is particularly prominent in the winter. Thermostat valve is not open to the appearance of features caused by the hot water tank and the water chamber Shui room cool. You should be checked, replaced.
Use and maintenance of vehicles to replace the winter, add antifreeze fluid
The onset of winter, the weather is cold, should be promptly replaced, adding antifreeze (antifreeze at least once every two years to replace if the water had been added to the maintenance of antifreeze in the summer, then winter, antifreeze best replacement ); replacement, add a glass of water antifreeze. Found mixed plus timely replace all; replace, add oil in winter apply.
Why start preheating
(1) winter cold car needs to warm up. After idling car starts to warm up. (In general, the engine after a night of standing, residual oil pressure of each friction surface has long since disappeared, lost film protection; hypothermia greatly increase the viscosity of the lubricant at this time, adhesion and mobility deteriorate to start the engine. greatly increase the resistance movement, when more than 60% of the power starts to overcome the resistance movement are cooler.
(2) cold start the engine, then go start the car. Since the mixing ratio of the non-uniform, less engine power output; low temperature, the atomized fuel can be insufficient combustion, easy to form coke; portion gasoline no fog, mixed directly into the crankcase and oil along the cylinder wall, reducing the quality of the oil . So cold machine must be idle to warm up for 3-5 minutes. )

Note Clean the throttle
With the advent of "March" winter, the car has entered a "susceptible" period, you should pay attention to clean the throttle. (Winter morning is not easy to name the car, many of my friends find good car yesterday, but you can not start the majority of this failure is caused by excessive intake of carbon, like other parts of the throttle too dirty; winter car driving to 15,000 km or so, should be promptly cleaned throttle check, this can prevent the occurrence of such a good situation.

Vehicle washing Precautions
(1) Wash the winter should be taken to avoid cleaning the engine compartment, if the timing belt on the water freezes, the toothed belt is easy to jump teeth cause valve timing disorder, ranging from the impact engine performance, heavy piston and valve collision , damage to the engine.
(2) It is worth noting that after washing the car, do not stop immediately to the cold outdoors, so there are water droplets freeze between the brake pads and rotors, so start the car very "difficult", but also damage brake pads.
Matters rain and snow should be noted
(1) of rain and snow should note that there will be snow on the brakes, pull the handbrake if the next evening parking disc may be frozen in the morning. When this stop, try to find support fixed vehicle brakes were frozen avoid occurrence.
(2) rain and snow, when the trunk open note, when you turn too hard, accumulate in the lower part of the windshield to the rear window of the ice easily crushed.
(3) It should be noted snow vehicle wash, because as the city increasingly serious pollution, corrosion impurities more snow, coupled with snow removal, etc., of the vehicle damage is very serious. Even within a few days will be snow, nor dragging not wash. As long as the snow-covered, it is necessary to flush immediately with water. Whether it is paint, chassis or tires, wheels, long snow cover will cause corrosion damage.
It should be noted winter fuel
It should be noted winter fuel. Due to low winter temperatures, poor fuel atomization capabilities, coupled with our fuel quality is generally not high at this stage, the gum content is usually exceeded several times or even several times, in the car's performance is the winter each year more sticky valve phenomenon, namely gasoline incombustible components deposited on the valves and valve springs back, the light idle instability, lack of motivation; severe valve piston crown can not even start. If you suspect your car gumming, the light can be used to avoid demolition washing machine wash, heavy wash once the engine cylinder head, which can reduce or avoid the trouble occurred.
Winter maintenance batteries
(1) It should be noted winter battery maintenance. Winter car's power consumption is much greater than in other seasons, in the winter, special care for the battery is quite necessary. Although we are using a maintenance-free battery, but not maintenance-free batteries do not need any maintenance, also need to regularly observe the view window colors (green is normal; black needs to be charged; white needs to be replaced) Check the voltage in the normal state (> 12V) and voltage at start (not less than 1OV within 5s). If the voltage is too low and should be supplemented charged or replaced.
(2) before the onset of winter, the pile should clean the battery terminals and apply special grease to protect and ensure a reliable start to extend battery life. If the car is parked in the open air or cold for several weeks without, you should remove the battery and store in a warmer room, to prevent battery power loss. (Basic general battery life is 2-3 years, suddenly no electricity expire easily, need to be replaced)
Maintenance winter tires
(1) winter tires should pay attention to maintenance. A thousand miles begins with a single step, as the car's tires "foot" is the only automotive parts in contact with the ground, is one of the important factors directly related to cars with security. According to relevant statistics on traffic accidents on the highway found that about 60% of a major accident is due to a flat tire burst caused. Tire failure is considered to be the number one killer highway.
(2) at least once a month to check all tires (including the spare included) pressure in the cooling conditions, this pressure value to carmakers information provided prevail.
(3) Always check tire condition, if found to have damaged or irregular tread wear, tires must be checked immediately by a professional.
(4) tire wear to wear signs, you should stop using it.
(5) Only trained personnel may install tires and tire and rim combination to do the balancing wheel
(6) If it is found irregular tread wear or vehicle shake, then immediately check wheel alignment and balance.
(7) to prevent oil / acid / hydrocarbons and other chemicals damage the tires.
Winter outdoor parking Precautions

Placed in front of the vehicle winter outdoor parking stall, plus the best kicks throttle around 3000 rpm, the exhaust pipe to drain the water as much as possible, this will help smooth start the next day. (Because the exhaust pipe in the water is not drained in time, then the next day will produce ice block, impede the exhaust, causing difficulty in starting, body shake, breathing and other failures.
