After opening the fuse box under the driver's seat, there is a 30A fuse, which is the sprinkler fuse. As shown below: Fuse, also known as current fuse, is defined by IEC127 as “fuse”. Its main function is to protect against overloads. Place the fuse correctly in the circuit.
Let the engine run at medium speed or higher. The standard voltage value of 12V electrical system should be around 14V, and the standard voltage value of 24V electrical system should be around 28V. If the measured voltage is the battery voltage, it means that the generator does not produce electricity.
Detailed information:
The wiper motor assembly includes the wiper motor, reduction mechanism, reset switch, disjunctor, capacitors C3 and C4 and inductor L. There are 5 wires in total, which are of high quality. speed wires 4 (+2), low speed line 1 (+1), power line 2 (B), reset line 3 (S), and ground line 5 (E).
The automatic reset switch is a single-throw, two-position automatic switch. When the wiper blade returns to the lowest position of the windshield, the reset wire 3 is connected to the ground wire 5, that is, contact A. is closed.
1. Engine oil and engine filter
Engine oil and engine filter can be considered as the two most fundamental but also the most important elements when it comes to maintenance. be replaced each time. Things, it goes without saying. However, the issue of maintenance time intervals/mileage has been debated endlessly, but there is no single result. Additionally, maintenance time/mileage intervalsof different car models and series are also different.
2. Air filter element and air conditioning filter element
The air filter element is related to the engine breathing smoothly, and the air conditioning filter element is related to the air. quality in the car. Both are important. The author believes that according to the maintenance, it is enough to replace the replacement cycle in time according to the manual, of course, there is no problem if it is appropriately advanced or delayed about 10,000 kilometers .
3. Glass of water, antifreeze and air conditioning refrigerant
Antifreeze is a very ignored thing by car enthusiasts, because antifreeze generally does not decrease. However, antifreeze also has a shelf life. Over time, it will deteriorate and add a lot of moisture, which will affect the cooling effect of the engine. It must therefore be replaced in time. You can refer to the maintenance manualien for the specific replacement. cycle. It is usually replaced every 40,000 to 50,000 kilometers.
Air conditioning refrigerant: When you feel that the cooling effect of the air conditioner is not good, if it is due to the lack of air conditioning refrigerant after inspection, you can add it according to the quantity.
4. Brake fluid, transmission oil, power steering oil, clutch oil, differential oil
Brake fluid: There are instructions in the service manual, usually for replacement at 40 000 kilometers. Brake fluid should be tested before it needs to be replaced. The general inspection method is: take a sample, then use an instrument (magnifying glass) to observe the moisture content of the sample. If the content exceeds the standard, it should be replaced.
Transmission oil: replace according to service manual, usually at 80,000 kilometers.
Power Steering Oil: The power steering in most vehicles is now electrically assisted, which also requires no maintenance. If your car's power steering is hydraulic, you should also replace the power steering oil in time. Please refer to your service manual for replacement cycle.
Clutch oil: Friends of manual transmission models should note that the clutch oil also needs to be replaced, to ensure smooth operation of the clutch for a long time. Please also refer to the model's service manual. replacement cycle.
Differential Oil: Many car enthusiasts may not know what a differential is. Actually, you don't need to understand it well. In fact, every car has at least one differential. Generally speaking, differentials without differential lockThey do not need to replace the differential oil. Models that need to be replaced can simply replace them according to the replacement intervals required in their own service manuals.
5. Battery
The battery generally has a lifespan of at least 2 to 3 years. Develop good car habits. Simply put, try not to use electrical appliances with the engine off. for a long time, good car usage habits can extend battery life. When a car has trouble starting, it's time to replace the battery.
6. Wiper blade, wiper motor, glass water pump
Wiper blade: When you find that the wiper cannot clean the glass, or When the wiper makes abnormal noise, the wipers need to be replaced. Windshield wiper motor, glass water pump: replace them in case of malfunctionnt, otherwise ignore them.
7. Drive Belt
Drive belts for generators and air conditioning compressors can typically be used for more than 50,000 miles. If they are linted or badly damaged, they should be used. replaced.
8. Spark Plugs
The spark plug replacement cycle is similar to that of engine oil, depending on the level:
① Ordinary alloy spark plugs nickel: replace every 15,000 to 20,000 kilometers;
② Platinum spark plugs: Replace every 40,000 kilometers;
③ Iridium spark plugs: Replace every 40,000 to 60,000 kilometers
④ Iridium-platinum spark plugs, dual iridium spark plugs: replace all 100,000 kilometers;
⑤ Competition Platinum Iridium Spark Plugs: Typically used for supercars and other models, they are expensive and cyclereplacement depends on actual testing. terms.
9. Fuel filter
Many people only know that engine oil has a filter, which must be replaced during each maintenance. This is because fuel also has a filter, and the price is usually much more expensive than an oil filter. It also needs to be replaced, but the replacement cycle will usually be longer, it can be replaced every 80,000 kilometers. refer to your own maintenance manual for details.
10. Throttle valve
Generally speaking, the throttle valve only needs to be cleaned of carbon deposits regularly when you feel that the idle speed is unstable, shaking and the acceleration is unstable. low, you can clean the throttle valve.
11. Ignition Coil
pointUsually, the ignition coil does not need to be replaced. If you notice that the vehicle is shaking abnormally or is unable toIf you want to accelerate, you can go to the 4S store to check whether the ignition coil is defective.
12. Brake pads and brake discs
The replacement cycle of brake pads and brake discs is closely related to each person's driving habits and the driving environment (road conditions). fixed standard. Generally speaking, it is said that a set of brake pads can be used for more than 40,000 kilometers. Some models are equipped with warning sounds or warning words, which is more practical. But there is no need to worry if it is not equipped with one. When the friction material of the brake pads wears to the warning line on the steel back (the technician can check this at each service), replace the brake pads of the brake rotors; , generally speaking, replace the brake pads twice. It is best to replace the brake disconce. The wear limit of the brake disc is generally 2 mm.
13. Shock absorbers and shock absorber springs
Shock absorbers and shock absorber springs generally have a long life, especially shock absorber springs. Generally speaking, shock absorbers do not need to be replaced if there is no serious oil leakage, serious abnormal noise or functional malfunction, otherwise they need to be replaced. If the shock absorber spring does not break due to accidents or quality problems, there is no need to replace it.
14. Original tire text link: http://www.okeycar.com/news/c-17/245700.html
The tire replacement cycle is similar to that of brake pads, so simply by Due to different driving habits and different road conditions, tire wear will be very different. Some violent elements will burn the tires at every turn. So what's the matterdoes he say? if we have money and will. However, tires also have wear limits, and each tire will have numerous wear limit marks, all located on the tire's longitudinal drainage grooves. As shown in the photo above, the place pointed by the finger is the limit wear mark of the tire, which is generally 1.6mm thick. That is, when the tire tread is worn down to be flush with this mark, it means that. the tire needs to be replaced. It's as simple and crude as that.
