The most important thing after buying a car is maintenance。Well-known，Cars require regular maintenance to maintain good performance。Then，Do you know what is the project for car maintenance regularly?？Nowadays， I will evaluate some of most common car maintenance。
1。 Primary maintenance
1。clean：No cleaning car surface，It refers to something more detailed.，Air filter, such as cleaning and replacing engine，Check the handle of rotating machinery，Cleaning sediment, etc.。
2。main body：This check is mainly to check if the screws of the main body and other attachments are firmly tightened.。In order to ensure that the vehicle is driving，Good part of the body is good。
3。grease：The project is mainly to check the height of the crankcase， Oil and brake liquid level，If exceeds the standard height，It is harmful to cars。Also check the water of the whole car， oil， Leakage。
4。Inspection equipment：Automobile level maintenance requires inspection of various equipment in the car。Transforming device such as a three-way catalytic converter； heat sink， Intravation Chemical oil， fan， Air compressor， Generators and other important small parts in the automotive。
second， Secondary maintenance
1。Engine part
（1）Start engine，Listening to the engine， Noise and abnormal noise in medium speed and high speed operation。
（2）Check cylinder pressure or vacuum，If necessary， Clear the carbon and ground valve in the combustion chamber， Adjust the valve pin，Check if the oil seal and the crankshaft bearing oil leak。
（3）Remove the oil and gasoline pump according to case，And clean；Test and adjust on the test bench as necessary，Make it compliant； Remove and replace air filter and replace oil oil，Clean the gasoline filter and check the pipeline and connector。
（4）Check and tighten the cylinder head，Intake and exhaust manifold and muffler bolts and nuts，Check engine fixation，Connection and fastening of flywheel and cylinder blocks。
（5）Clean crude oil filter and fine oil filter，Remove and clean the oil dish，Cleaning oil pump and oil，Wipe and check the cylinder wall，Check bearing，Install the oil housing？Tighten the new oil to the designated oil level as needed。
（6）Check the working status of the air compressor and the sealing of the pipeline，Adjusting the belt looseness，Remove oil， Water and dirt in air storage check wiper and its airway。
（7）Check the fixation of radiators and lids， Whether the working status of the water pump is leaking，Water pump shaft，Check the efficiency of blinds。
2。Clutch and gearbox parts
（1）Check clutch performance and bottom cover bolts，Adjust the free trip to the springboard，Fatten on the springboard。
（2）Check universal joint，Change the direction of the ten axis according to the situation，Check if the drive shaft and the telescopic sleeve are loose，Check intermediate support and bearings，Add oil，Tighten the trailer hook nut。
（3）Check the working condition of the handlock，Machine connection and fastening，Adjustment，Lubricating boom。
（4）Remove the main speed reducer and differential depending on the situation，Check the meshing of the gear，Adjust the tightness of the bearing，Add or change gear oil，Dredging exhaust hole，Check if it is oil，Tighten screws and nuts。
3。Electronic equipment
（1）Check the specific gravity of battery electrolyte，Filling electrolyte proportion，Inject distilled water and add，Piles coated with Vaseline，To prevent corrosion，Dredging the venting hole，Check the boot circuit，Fixed battery bracket。
（2）Check the condition of all electrical equipment and cars，Check and adjust the horn working conditions， Indicator light brake light Steering lamp， Headlights and many more Electronic instrument，Dismantle Cleaning and lubrication dispenser，Taking check of spring tension and vacuum regulator working conditions，Check the performance of the capacitor and ignition coil。
（3）Check and clean the leakage generator and regulator starter，Test its performance，each6000?8000kmDuring the second maintenance（Can increase or decrease depending on the case），Negative inspection must be prevented for disassembly of generators and starters，Eliminate hidden dangers。
4。Tire parts
（1）Remove stones in the tread pattern，Check if the tire is bubble， Stratification Crack deterioration， Ageing， and many more
（2）Remove the tire，Rust，Check if the internal tires and vows are damaged or disassembled，Inflatable according to the specified air pressure，Tire flaps or shift。
（3）Check if there is a friction between the tire and the wing， Box floor Leaf spring Fender。
5，Vehicle examination item
Check if all the appearance of the car is in good condition and paint，Check if the frame has cracks and loose rivets，Check the working efficiency of the brake system and the sealing of the pipeline，Check the working conditions of the steering system and the working conditions of the underarm number and lighting，Check the lubrication in accordance with the rules in the whole vehicle lubrication map，If you find problems or unqualified，Adjustment and repair by related work and workstation types, respectively。Working on the engine to listen to the operation of the engine while the engine acceleration and low speed，Is there a normal sound? Is there an abnormal sound?，Test 易彤破壁料理机维修 the braking performance of the brake at various speeds，Should be deviation， Tremor Brake fault and abnormal noise，Car parked in a straight slope，Tighten the handbrake should stop moving。After a certain distance from the road test，Check gearbox， Rear bridge main gearbox， Brake drum and many more overheat。After the road test discovery，Should check it out Adjustment and elimination immediately。
Don't ignore the daily maintenance of the car，Regular maintenance，Stable car performance，In order to fundamentally guarantee driving safety。
