What Maintenance is Needed for a Car at 30,000 Kilometers?

Generally, the maintenance items for a car at 30,000 kilometers include changing the engine oil, oil filter, air filter, fuel filter, throttle cleaning, and replacing spark plugs. Some 4S shops may recommend additional maintenance items, which can be considered based on personal preference and actual conditions. Below are some extended details: 1. Engine Oil and Four Filters: The four filters in the engine oil system include the oil filter, air filter, fuel filter, and cabin air filter. The oil filter should be replaced at every maintenance interval, while the air filter is recommended to be replaced every 10,000–15,000 kilometers, the fuel filter every 30,000 kilometers, and the cabin air filter every six months. To save costs, you can skip replacing the cabin air filter. However, the fuel filter must be replaced during the major 30,000-kilometer maintenance. 2. Throttle Cleaning: Throttle cleaning is unnecessary before 30,000 kilometers. If a 4S shop or repair shop recommends this service at 10,000 or 20,000 kilometers, you can directly refuse. Over time, carbon deposits accumulate at the throttle valve due to prolonged air intake, leading to reduced airflow. This can cause minor idle instability, idle shaking, weak acceleration, and indirectly increase fuel consumption. 3. Spark Plugs: Spark plugs should be replaced at 30,000 kilometers. Although they may not have completely lost their ignition performance by this point, their efficiency is significantly reduced. Poor ignition performance directly affects idle shaking, engine misfires, and weak acceleration. It also increases engine load, contributing to higher fuel consumption. 4. Air Conditioning Cleaning: Air conditioning cleaning removes dust, dirt, and bacteria from the air conditioning system. This service is optional. If the car has never undergone air conditioning cleaning before 30,000 kilometers, it is advisable to do it now.

How Much Engine Oil in the Car is Considered Normal?

Generally, the engine oil level in a car is considered normal when it is between the upper limit (MAX) and the lower limit (MIN). The optimal oil level is slightly closer to the upper limit. If the oil level is below the lower limit (MIN), it is not normal and requires maintenance. Additionally, when checking the oil level, the dipstick should be fully inserted. Below is more related information: 1. Functions of Engine Oil: "Engine oil" is an essential lubricant for ensuring the normal operation of the engine. Its specific functions include lubricating metal components, reducing friction between parts, dissipating the immense heat generated during engine operation, cleaning fine metal particles produced by wear, as well as providing sealing, vibration damping, and rust prevention. However, when adding engine oil, it is important to ensure the amount is neither too much nor too little. The oil level should be between the "low" (MIN) and "full" (MAX) marks on the dipstick. An oil level that is too low can lead to insufficient oil pressure, while an excessive oil level can increase the working resistance of the crankshaft and connecting rods and accelerate the formation of carbon deposits in the combustion chamber. 2. Precautions: After changing the engine oil in a car, the oil level should generally be between the lower line (MIN) and the upper line (MAX) on the dipstick. It is advisable not to exceed the upper line. Overfilling can cause issues such as foaming due to the crankshaft's agitation, which may damage the engine. Staying below the upper line is safe. After starting the engine, the oil level should ideally be in the middle to upper range. Overfilling may lead to problems like sluggish engine performance and oil seal leakage.

Why Does the Fan Keep Running After the Car Is Turned Off?

Fan keeps running because the engine coolant temperature is too high. Here is some extended information about high engine coolant temperature: 1. Causes: There are several reasons that can cause the engine coolant temperature to rise excessively or even boil over, such as damaged electronic components in the cooling system (thermostat, cooling fan), poor radiator performance, or insufficient coolant. 2. Solutions: Check if the lack of antifreeze is causing the high engine temperature. Also, inspect the coolant circulation to see if it is obstructed. Additionally, components like the coolant temperature sensor, water pump, thermostat, and cooling fan could all contribute to high temperatures. It is recommended to visit a repair shop for maintenance.

How to adjust the valve clearance of the SFH C9 engine?

No need to remove the magneto cover. Insert a 17mm socket into the valve position, shine a light inside, and you will see a marking line. Adjust the valve clearance by aligning with this line. Remove the valve cover, then remove the cylinder head. You will see two screws. First, shake them slightly to feel the clearance, then adjust it to be slightly smaller.

How to Align with the Pole Line in Ramp Parking?

Wiper alignment method: When the convex point of the wiper, the parking pole marker, and your line of sight form three aligned points, apply the brakes. Many test items require line tracking operations. Use the right front 1/3 section of the engine hood for line tracking.

Why Won't My Car Start When It's Fine?

There are several reasons why a vehicle may not start: a dead battery, possibly due to leaving headlights on for an extended period; expired battery life, often caused by installing xenon headlights, high-power audio systems, or DVD players; incorrect gear position - automatic transmission vehicles must be in P or N gear to start; not depressing the clutch - manual transmission vehicles won't start without clutch engagement; excessive carbon buildup in the engine can also prevent starting. Below is more relevant information: Precautions: Always pay attention to electrical usage in the vehicle. Remember to unplug external devices like car computers or displays when exiting the vehicle, and ensure all lights are turned off. Additionally, regularly monitor dashboard warning lights. If the battery warning light remains illuminated while driving, promptly visit a repair shop or 4S dealership to address the issue.
