1. Timing belt
The so-called engine timing means that the engine will adjust the opening time of the intake and exhaust valves according to the engine speed, thereby improving the efficiency of the intake and exhaust. , accurate ignition time and improved engine fuel economy, but since it is the timing belt, it will age, so the timing kit needs to be replaced regularly. (Many of them now use timing chains so there is no need to replace them.)
There is no need to replace it regularly but it depends on the amount of use . Antifreeze can prevent coolant from freezing and. expands when parking in cold winter. Crack the radiator and freeze the engine block or cylinder head. But a misunderstanding must be cleared up. Antifreeze is not just for winter, it must be used all year round.
Articles fromcleaning: throttle valve (disassembly and cleaning), fuel injector, intake bypass pipe, three-way catalysis (these three are recommended without disassembly and cleaning, and hanging bottles are now used by many repair shops. Simple and avoids damage to original parts)
2. Brake pads
Brake pads are a very important accessory but it is very uncertain to determine the replacement time in general. brake discs It will take longer than brake pads. Since driving habits and usage conditions are different, the service life of the brake pads will be different. Therefore, after a certain mileage, regular inspections are necessary to ensure braking force. Brake pads are usually replaced if necessary. brake pads are replaced. Replace a set of discse brake and brake pads symmetrically and simultaneously to ensure balanced braking force on both sides and avoid braking deviation.
The brake disc is a metal disc made of alloy steel and fixed to the wheel, rotating with the wheel. When the vehicle brakes while driving, the brake caliper squeezes the brake rotor to slow or stop the vehicle.
Generally, there are round holes on the brake disc, which are used to reduce weight and increase friction. There are many types of brake discs, characterized by thin walls, and the disc and center are formed by a sand core. Different types of brake discs have differences in disc diameter, disc thickness and gap size between the two discs. The thickness and height of the disc hub are also different. After-sales service technicians will check the brake disc each time it is replaced.brake pads. It is recommended to replace the brake disc once after replacing the brake pads twice.
3. Wiper blades and tires should be replaced depending on use.
The wiper blade is a commonly used bodywork accessory. It is mainly used to wipe rainwater from the windshield in rainy days and is also used to wash the windshield. There are about two types of wiper blades, one is ribbed wiper blade and the other is ribless wiper blade. Most of these wiper blades appear on mid to high-end cars. A good wiper blade should have the characteristics of heat resistance, cold resistance, acid and alkali resistance, corrosion resistance, ability to fit the windshield, reduce load on the motor, low noise, fgreat water repellency, softness and no scratches on the windshield, etc., and can be used. You have a clear vision.
Tires should be rotated regularly to ensure grip and increase lifespan. After reaching a certain level of wear, tires must be replaced.
Detailed Information“Minor Maintenance” mainly includes changing the engine oil, oil filter and performing routine inspections. Car engines need lubrication and engine oil plays the roles of lubricating, cleaning, sealing and cooling.
However, as the car drives, the base oil and the additives contained in the engine oil will deteriorate and fail. Therefore, in order to protect the engine, engine oil should be replaced regularly. Major maintenance relies on the existence of minor maintenance. Generally, these two types of maintenancewere carried out alternately. Intervals vary by car brand and specific recommendations are based on manufacturer recommendations.
Generally, the original battery of a car can be used for at least 3 years, but you should pay attention to the reasonable use of the battery and avoid excessive discharge. For example, don't watch videos, listen. to music, etc. when the engine is off for a long time.
Another very common phenomenon is that you forget to turn off the car lights when you park and find that the battery is completely dead the next day. This leads to fatal damage to the battery. the battery will no longer last.
Finally, when replacing batteries, reconditioned batteries are particularly easy to appear on the market. Generally, there is no problem in choosing batteries from major brands.es such as Valta, Yuasa, Hitachi, Fengfan and Uni-President. GS. Don't buy fake products.
Can a Porsche still run if it is missing a cylinder?
Install the Porsche Cayenne 3.6 alternator belt and use a wrench to turn the Porsche Cayenne 3.6 Alternator belt upwards counterclockwise. After loosening the Porsche Cayenne 3.6 tensioner screw, pull the Porsche Cayenne 3.6 alternator belt back and forth with your hands to loosen the Porsche Cayenne 3.6 alternator belt. Once the Porsche Cayenne 3.6 alternator belt is loose, tighten it. Porsche Cayenne 3.6 Alternator Belt Remove the Cayenne 3.6 alternator belt from the alternator pulley; the specific steps are as follows:
1. Use a wrench to turn the Porsche Cayenne 3.6 alternator belt tensioner screw counterclockwise.they of a watch.
2. After loosening the Porsche Cayenne 3.6 tensioner screw, pull the Porsche Cayenne 3.6 alternator belt back and forth with your hands to loosen the Porsche Cayenne 3.6 alternator belt.
3. Once the Porsche Cayenne 3.6 alternator belt is loose, remove the Porsche Cayenne 3.6 alternator belt from the alternator pulley.
4. Hook up the new generator belt.
5. Start the Porsche Cayenne 3.6 engine and check if the belt turns normally.
6. Lock the Porsche Cayenne 3.6 alternator tensioner and the operation is complete.
The Porsche cannot be driven due to the lack of a cylinder. A car cannot continue to drive without a cylinder. The lack of cylinders in the engine is mainly caused by the ignition system and fuel injection system, which will cause the power of the car to drop et power will fluctuate between high values. and weak at idle.
The main body of the engine, which integrates the cylinders and the crankcase, is the support frame for the installation of pistons, crankshaft and other parts and accessories.
The role of the cylinder block
The working conditions of the cylinder block are very harsh. It must withstand rapid changes in pressure and temperature during the combustion process as well as high friction from piston movement. have sufficient strength and rigidity and small deformations ensure the correct position of each moving part, normal operation and low vibration and noise. It has good cooling performance and there is a cooling water jacket around the cylinder to allow the cooling water to discharge heat.
Wear-resistant to ensure sufficient cylinder block life. The part knownThe upper part of the cylinder block is a parallel cylinder, which is currently mainly equipped with a cylinder liner. The lower part of the cylinder block is the crankcase, which is used to install the crankshaft. Various accessories such as generators and engine mounts can also be installed externally.
Cylinder blocks are mainly made of cast iron or aluminum alloy. Aluminum alloy cylinder blocks are more expensive, but are lightweight and have good cooling performance, so they are increasingly used.
