Hot weather, the temperature increasing, especially margin fan clutch tells you cause the water temperature is too high there will be several Symptom:
1 , in bad traffic , traffic jams or prolonged idling , the engine temperature is too high table displays , electronic fan speed gear long working hours , the engine noise increases when the temperature is too high air conditioning failure is most obvious.
2 , the air conditioning when the temperature is too high , unstable idle speed floating too large, hard acceleration weakness, abnormal sound engine .
3 , ten minutes after the car turn off the heat , not easy when you start the car , driving the car when the heat is sometimes automatically turn off.
4 , cold car air conditioning and refrigeration temperatures cool, hot car air conditioning and refrigeration effect is not obvious ; And hum a greater resonance in the air conditioning system.
5 , when the hot car idling , the air conditioning compressor clutch sucked off frequently, even disconnected, resulting in a hot car air conditioner is not cooling .
Automotive engine water temperature is too high Solution:
1 , hot car, return pipe Check the antifreeze backwater top of the storage tank , if poor backwater or blockage will cause the water temperature is too high.
Reminder: Do not blindly in the maintenance of dismantling and replacement parts .
2 , check the condenser and the dust is too much between the tank and thoroughly cleaned with high-pressure gas tank and condenser to ensure good heat dissipation.
Reminder: the usual attention to wipe the dust between the condenser and the water tank .
3, in the hot car , check the temperature difference between the water tank and down pipes , if the temperature difference is too big , you need to check the thermostat opening and the speed of the pump if there is a fault throw switch .
Reminder: the temperature difference between the water tank and down pipes can not be too large.
4, due to the addition and replacement of antifreeze is not standardized , it will cause the engine clogging waterways and water tanks in advance , appear high water temperature phenomenon. Antifreeze replaced every two years , you must use original parts when replacing and adding .
Reminder: the engine cooling system after adding water, or adding antifreeze concentration exceeds more than 60% , will cause the water temperature is too high.
5, the air conditioning system high side pressure is too high ; air conditioning refrigerant or air conditioning and refrigeration lubricants overfilled ; internal self- debugging features self-adjusting air conditioning compressor failure , resulting in high pressure is too high ; still clogged air conditioner condenser , above will increase the load on the engine failure , the consumption of the cooling system thermal performance, high temperature lead system malfunction .
There are car maintenance tips , special margin fan clutch teach you how to take good care of the car :
First, car maintenance " three filter " first
" Three filter " means air filters, oil filters and fuel filters, air , oil and gasoline will be over a hurdle, providing clean engine oil , and thus play a protective effect on the engine , but also improve the efficiency of the engine.
1, the fuel filter
Note the use of the standard 93 # ⑴ oil, because substandard gasoline will cause premature failure of the fuel system and engine failure .
⑵ When found insufficient fuel , engine power down when the vehicle is traveling weakness, you should check the filter is clogged .
⑶ general requirements should be replaced every 15,000 km with fuel filter .
2 , air filter
⑴ when cleaning the air filter, remove the filter with a soft brush to brush along the crease direction dust filter surface and gently pat the end face to get rid of dust. It should be noted at this time with a clean cloth or rubber stopper blocked at both ends of the filter to prevent dust and then sweep down into the filter surface .
⑵ careful not to water or diesel , gasoline clean the filter , because it will clog the filter pores moist dirt , self-defeating , but also increases the air resistance , and easily inhaled diesel cylinder , causing the start coaster after installation.
⑶ filter if found damaged , uneven or warped filter upper and lower end , or rubber seals deformation aging , damaged , replace with new parts.
3 , oil filter
Generally replace the engine oil every 5,000 km , while replacing the oil filter once .
Second, the safety brake system
Know your car
⑴ If your car is a new car or just replace the brake linings , 200 kilometers braking effect may not be the first to do so , subject to the run-in order to achieve the best braking effect , you can increase the system through appropriate dynamic braking method earlier time to compensate.
⑵ When the car in heavy rain or washing after wading , brake linings wet braking effect will decrease slightly , then should start back with side light brake pedal , the brake discs and brake friction linings heat to evaporate the moisture and restore the braking effect , the brake parts can be prevented from rusting .
⑶ If your car is damaged or deformed front spoiler will change the direction of airflow , resulting in poor braking system cooling and overheating, even ablation brake discs , so this should be spoiler damage promptly repaired or replaced.
Good security is guaranteed driving habits
⑴ before moving to develop and test the brake pedal before the downhill habit of checking the braking effect is good. If the pedal stroke abruptly , it could be a brake circuit fails, the vehicle can still brake at this time , but the braking effect is reduced, the brake pipe of a larger work load , and therefore can not make car work long hours in this state , you should drive slowly to the nearest service station to check and troubleshoot .
⑵ To ensure the normal work of the brake pedal , the pedal can be stepped on in the end . So , put the foot can not be placed in front of the driver's seat so as not to slide under items affecting pedal brake pedal while working stroke .
⑶ Also pay attention to check the adequacy of the brake fluid , brake line interface without leakage , allowing you to drive all the way to ease the routine maintenance .
Zhidongshiling countermeasures
⑴ psychologically to be calm , the more scared the more error-prone operation.
⑵ quick downshift or use leapfrog downshift .
⑶ use of frictional resistance inside the engine and work to produce the car led hindrance .
⑷ Trial hand brake to allow the car to force auxiliary foot brake deceleration .
⑸ see the road , a good grasp of the direction , so the car as much as possible in a relatively large resistance of the roads , in the case of last resort can be a big car towards the roadside
Third, routine maintenance lubrication system
⑴ oil is not better
Sump oil should be controlled within the dipstick down tick should not be too much or too little .
If too much oil , causing the engine to various parts of the friction increases , engine power loss. And too much oil will jump into the combustion chamber , the engine burning oil , oil consumption increased significantly, increased internal engine carbon deposits , and even lead to early ignition , knock , pulling cylinder , severe damage to the engine , the oil has really lost it off Bing .
Conversely , if the oil is too small , some of the parts of the engine can not be sufficiently lubricated , resulting in abnormal wear of parts .
Check the oil ⑵
Regularly check the amount of oil is an important routine maintenance tasks .
⒈ check the oil level when the car must maintain a horizontal position, the engine stopped, wait a few minutes so that the oil back into the oil pan .
⒉ out the dipstick , wipe dry with a clean cloth , then re-insert the dipstick , has been stuck in the end .
⒊ dipstick out again and then observe whether the oil between the max-Dmin.
If the oil level below the sign below the recommended requirements should be based on the user's manual or on a service station , add the same species meets the specifications of the engine oil , about one liter of engine oil can make the film on the oil level dipstick reach on-line.
⑶ oil quality check
Check the fluid level in the oil , but also by how the wind blows , nose sniffing method of testing the quality feel of the oil to make their lubrication condition of the engine and always be aware of.
Grossly : If the oil clean clear and bluish- brown or greenish brown , said oil pollution is very light.
If the surface film of water droplets or pale yellow foam milk indicates that there is water mixed with oil .
If the oil was gray shape , then the oil has been seriously polluted, the oil should be replaced .
Sniffing : If the nose can smell the thick of gasoline , then the cylinder and parts piston rings, pistons and other serious wear and tear , so that the mixture into the pan and exhaust leak and cause , you should go to the service station in a timely manner maintenance.
Feel: squeeze a small amount of oil by hand twisting , if feel rough , it indicates that the oil has been mixed with a lot of metal shavings and other impurities ;
If you feel more dilute the oil , it is likely that the mixture of gasoline dilution caused overhaul and repair station should go change the oil .
If you feel there are too viscous oil and glial sense , then the oil has aged deterioration of its life and should be replaced with fresh blood .
Fourth, pay attention to the battery using eight
Battery power is one of the main vehicles, is a relatively short-lived component , to be used to strengthen the maintenance, otherwise easily lead to premature failure .
If it is initiated complaints , the vehicle may be necessary paralyzed.
( 1 ) often with warm water and scrub clean the shell and the head of the electrolyte electrode column clamp and dirt , and then coated with a layer of Vaseline film , avoid corrosion pole and wire clamp to keep the housing clean and dry .
( 2 ) Check the electrolyte level should be kept liquid located between max-Dmin marking , level too low to timely replenishment of distilled water , distilled water in the winter filling should immediately make the engine run a few minutes, the electrolyte mixing, filling distilled water to prevent freezing new ; when you add distilled water to prevent iron and other impurities fall within the battery .
( 3 ) Note that the dosing hole plugs to tighten the vent plug on maintaining smooth , otherwise the battery when the work will produce gas shell damage.
( 4 ) Note that when loading the battery must distinguish between positive and negative grounding polarity can not be wrong , so as to avoid damage to the generator . Remove the grounding line when the first split and then split the line of fire ; first install FireWire installation , installed after the grounding line , to avoid sparks .
( 5 ) Be careful not to start the machine continuously , every startup should not exceed 5s, 10s-D15s should be separated between the two , in order to avoid a large arched plate discharge caused damage .
( 6 ) found that lack of electricity should pay attention to replenish the charge ; according to seasonal changes , adjustments to the service station to check the electrolyte density ; electrolyte used should be pure, formulated electrolyte should be of high purity sulfuric acid and distilled water.
( 7 ) Note that the shell surface condition , found sealed plastic cracking, shell damaged, badly worn or broken pole should be repaired .
( 8 ) Note that the use of low temperature , should take special insulation, antifreeze measures taken by the engine warm-up and pre- heated to avoid cold machine starts , resulting in a large number of battery discharge .
V. Discussion tires
⑴ attention to tire pressure
High- low tire pressure can cause abnormal tire wear and shorten the life of the tire. In the climate is harsh winter and summer , you can adjust the tire pressure on a regular basis on the recommendation of service stations.
Avoid hard acceleration lane ⑵
The car suddenly started by the stationary state , so that the tire and the road surface friction dramatic , accelerated tread wear .
⑶ reduce emergency brake
Exacerbate local emergency braking tread wear , easy to cause tire from the package, delamination phenomena should be more use of slide deceleration , less braking , especially the emergency brake .
Economic speed fuel consumption ⑷ Province
Prolonged high-speed driving , not only increase fuel consumption , but also make a sharp rise in fetal temperature , the rate of increase of the tire and the road surface slippery drag on the tires and parts are negative.
⑸ wheel transposition
Front and rear axle load is different , resulting in four uneven tire wear , usually traveling to 10,000 km new tire , it should be around the same side of the transposition.
⑹ careful with the car loaded dissimilar tires
Shen same car tire mounted in two different sizes , because their pattern design, quality, diameter and other technical parameters are different, if the two different specifications of tire mounted on the same shaft , it will cause oversteer or less prone to skidding. Light affect the vehicle's handling flexibility , weight will cause an accident .
⑺ choice parking places
Parking place is good or bad choice , but also have a certain impact on the life of the tire , so the driver should be careful not to choose a parking spot in the car park there is oil, sharp ice , snow and other harmful road tires ; ramp on should try to avoid traveling in the slope parking ; during the summer driving For parking , you should choose a cool place and avoid exposure to the sun tire ; during the cold season driving For parking , sheltered sunny place should be selected to avoid the tires and the ground is frozen.
⑻ tire wear should be promptly eliminated
As tire eliminated , depending on their degree of wear , when to wear a flag revealed to be replaced , do not delay ! At this point the tires have been at risk , but will also increase fuel consumption . Also , for safety reasons , tire replacement should be replaced in pairs , can the newly replaced tires to play a good performance .
Sixth, the proper use of seat belts
1 , the use of seat belts
Seats, head restraints , seat belts and airbags are able to effectively protect the safety of passengers , but if used improperly , it may affect the effective performance of the play , the protective effect is not so. Here to talk about the use of seat belts a few precautions should be noted .
⑴ should adopt an upright riding posture, abutting the back seat when the seat back inclination should not exceed 30 degrees , so as to play a more effective performance of the seat belt to protect the safety of passengers .
⑵ too thick winter clothes make the seat belt becomes unresponsive , you can not play the best protection.
⑶ wearing a seatbelt when the method should also be noted , the lap belt portion should be reined in the pelvis , shoulder belts should cut through the middle of the chest and shoulder by snapping the body , careful not to make the seat belt through the neck to avoid accident .
⑷ wearing a seatbelt when the tongue into the buckle until you hear a click , then the seat belt is properly locked. If you can not pull the seat belt , pull over and then release it , pull the seat belt can ride , but you can not pull too fast , otherwise the belt will automatically lock .
⑸ seat belt can not be demolished , if there is a problem we must ask professionals to repair. When cleaning, car cleaners , or to use warm water and natural drying , baking can not be used as artificial heat , etc., so that the safety belt will affect the performance and service life .
⑹ a seat belt only to one person to use, can not be two people ( including children ) sharing a seat belt , seat belt can not be reversed in the use of attention , otherwise affect the results.
2 , airbags Precautions
Only seats, head restraints , seat belts and airbags together in order to most effectively protect the safety of passengers , the correct approach is to protect the safety of use .
⑴ when driving cars equipped with airbags , seat belts must be worn in order to avoid the pop-up balloon detonation damage to human impact .
⑵ not put objects on the surface of the steering wheel airbag to prevent accidental pop .
⑶ non-professionals , not without inspection, disassembly airbags, as this may cause you injuries.
⑷ collision after the accident, regardless of whether the airbag detonation , repair station personnel should ask the relevant security systems do a complete overhaul .
Seven, skilled nursing window
⑴ windows should be kept clean , cleaning the dirt inside the strip can then be coated with a small amount of rubber maintenance agent , helps to lubricate , but also to prevent cracking aging strip .
Another reason for the action is not smooth ⑵ window is depleted oil lifts , lift your hands apart and then sprayed inside the gear oil . While moving up and down while spraying can make very small portion can be coated with grease.
⑶ If the glass is not completely down , there may be switch failure . Check the fuse is common sense . Read the manual carefully to see which one is the fuse for power windows . To see if the fuse , the fuse should be replaced if put on the same type of fuse.
