At 40,000 kilometers, car maintenance includes replacing engine oil, oil filters, spark plugs, etc. Below is a detailed introduction to the car maintenance items: Engine Oil and Oil Filter Replacement: This primarily involves maintenance for the lubrication system. The main function of the lubrication system is to effectively lubricate various components of the car engine. Under normal circumstances, the car should be serviced every 5,000 kilometers. Replacing the air filter is necessary as its role is to filter air before it enters the cylinders, removing impurities, dust, sand, and other foreign particles. Spark Plug Replacement: Spark plugs are consumable items and should be replaced every 20,000 kilometers. Additionally, components such as brake fluid, transmission oil, battery, throttle, fuel injectors, and brake pads are part of the inspection items during routine maintenance, and their maintenance should be carried out based on usage conditions.

Every time my car reaches 40,000 kilometers, I take it in for maintenance, primarily to change the engine oil and oil filter. This is the most basic upkeep to keep the engine lubricated and reduce wear. At the same time, I have the brake system checked to see the wear level of the brake pads and if the discs need adjustment, to avoid failure at critical moments. Tires are also crucial; I check the tread wear and ensure the tire pressure is even, rotating them if necessary to extend their lifespan. The air filter is usually replaced with a new one to improve air intake efficiency and save on fuel consumption. If the spark plugs haven't been changed yet, they should be checked as well, as too large a gap can affect starting performance. The coolant and antifreeze levels need to be topped up to prevent overheating issues. I perform these maintenance tasks regularly, which makes the car run more smoothly, with lower fuel consumption and less noise, saving on future repair costs. Typically, it takes about two hours to complete.

What are the symptoms of water entering a car battery?

Water entering a car battery can cause damage to the battery and lead to corrosion of the electrodes, so the battery needs to be replaced immediately if water gets inside. Here are some specific details about car batteries: 1. Function of the battery: When starting the engine, it provides a strong starting current to the starter and works together with the alternator to supply power to electrical devices. When the engine is idling, it powers the electrical devices. The car battery also acts as a capacitor, protecting the vehicle's electrical equipment. 2. Voltage: With the increasing number of electrical devices in vehicles and the emergence of mild hybrid systems, the 12V voltage is no longer sufficient, leading to continuous increases in voltage. Currently, the mainstream voltage for mild hybrid systems is 48V.

Can You Continue Driving with a Damaged Oil Cooler?

You cannot continue driving with a damaged oil cooler. This is because the oil can reach extremely high temperatures under such conditions, leading to increased oil evaporation in the oil pan and higher oil consumption. Oil also plays a cooling role, and its failure can cause the engine to overheat. In this scenario, the oil temperature will rise excessively, reducing its viscosity and compromising its lubrication effectiveness. Additional Information: Precautions: The oil cooler used in cars is a component with a relatively high failure rate. After the oil cooler is damaged, the most common symptom is excessively high oil temperature. If the oil temperature is too high, it not only accelerates oil consumption but may also lead to oxidation and deterioration of the oil.

Should You Pull Out a Nail in the Tire?

Tire punctured by a nail should not be pulled out. The reasons and handling methods for not recommending pulling out a nail from a tire are as follows: Reasons not to pull out a nail from a tire: Since the tire is in a rolling state while driving, the nail may not be vertically inserted into the tire. If the nail is pulled out without timely repair, the tire may become irreparable. The tire must be removed from the rim and inspected by a professional tire dealer to determine whether it can be repaired. Handling method for a tire punctured by a nail: If the tire is not flat, never pull out the nail, as the nail may help prevent air leakage at this time. You should quickly find a place to repair the tire and have a professional worker remove the nail and patch the tire. Do not drive for a long time.

Will water enter if the side mirror turn signal has cracks?

This requires testing to know. It is recommended to observe for a period of time. If water enters during car washing, simply replace the side mirror turn signal. Below is more information about side mirror turn signals: 1. Introduction: The turn signal is an important indicator light that is turned on when a motor vehicle is turning to alert vehicles and pedestrians in front, behind, and on the sides. The turn signal tube uses a xenon tube, controlled by a single-chip microcomputer circuit, with alternating left and right flashing for uninterrupted operation. The turn signal uses a flasher to achieve light blinking. It can mainly be divided into three types: resistance wire type, capacitor type, and electronic type. 2. Function: It makes it easier for vehicles or pedestrians traveling side by side to notice the vehicle is turning and to yield in time.

How Often Should Shell Helix HX5 Oil Be Changed?

If it is regular Shell Helix HX5 oil, it can be changed every 5,000 kilometers or every six months. However, if it is semi-synthetic Shell Helix HX5 oil, it can be changed every 7,500 kilometers or every 7-8 months. But these are just reference figures, and the specific time should be determined based on actual conditions. Here is additional information: Shell Helix HX5: Shell Helix HX5 is a mineral oil that focuses on cleaning performance. It not only has wear protection performance that other mineral oils cannot match, but when combined with long-term stable oxidation characteristics, it can increase engine protection capability by up to 30% compared to ordinary mineral oils, thereby effectively extending the service life of the engine.
