Antifreeze can be changed by yourself. Before changing the antifreeze, ensure the car is in a cold state. Open the radiator drain valve to drain the antifreeze; fill with clean water and keep the engine idling until clean water comes out of the radiator; wait for the water to drain completely, then close the drain valve and engine, and add new antifreeze until the liquid level is between the max and min marks. Antifreeze Replacement Cycle: Vehicle antifreeze generally needs to be replaced every 2 years or 40,000 kilometers. This is just a reference cycle. For commercial vehicles with longer mileage, the replacement cycle is shorter. Since driving conditions vary for each car, the replacement should be based on actual usage. Check the antifreeze condition regularly—if it is insufficient, top it up promptly; if suspended matter, sediment, or deterioration/discoloration is found, replace it immediately and clean the system. Function of Antifreeze: Antifreeze is a coolant containing special additives, mainly used in liquid-cooled engine cooling systems. It has excellent properties such as preventing freezing in winter, boiling in summer, and protecting against scale and corrosion year-round.

Can 0w30 engine oil be used in summer?

0w30 engine oil can be used in summer. The smaller the number before W, the better the fluidity of the lubricating oil at low temperatures, making it easier to start the car; the larger the number after W, the better the viscosity of the oil in high-temperature environments and the higher the strength of the oil film formed. Engine oil consists of two parts: base oil and additives. The base oil is the main component of lubricating oil, determining its basic properties. The steps for changing engine oil are: 1. Lift the car, remove the protective plate, and place a container of about 10 liters under the oil drain plug; 2. Unscrew the oil drain plug, use an air gun to blow for two minutes at the oil filler port, tighten the oil drain plug after draining, and wipe it with a tissue to check for leaks; 3. Reinstall the protective plate, lower the car, and use a funnel to add engine oil to the standard position at the oil filler port.

What are the reasons for the ABS warning light to intermittently turn on and off?

ABS warning light can indicate various conditions, each with different causes and solutions, as detailed below: Condition 1: ABS warning light stays on (most common). Cause 1: The ABS wheel speed sensor's sensing area is covered by dirt, mud, or other contaminants, affecting its ability to detect the corresponding speed signal. This prevents the ABS control unit from determining the vehicle speed and wheel slip rate, thus failing to issue appropriate commands to regulate braking. Solution: Clean the dirt from the wheel speed sensor and adjust the gap between the sensor and the tone ring to restore normal function. Cause 2: Loose connections in the system wiring or poor contact in the ABS relay can lead to signal issues and system failure. Solution: Inspect wiring connections and reconnect any loose parts. Condition 2: ABS warning light intermittently turns on but turns off when accelerating. Cause: When multiple vehicle electrical devices are in use, the battery voltage may drop below 10.5V. As the engine speed increases and voltage rises, the ABS warning light turns off. This can also occur if the ABS system's power supply voltage is too low due to poor terminal contact or grounding issues. Solution: Check the battery's specific gravity; inspect the charging system; examine the power supply (e.g., voltage relay or poor power contact). Condition 3: ABS warning light stays on after engine start and only turns off when the engine is turned off (IGFF). Cause: Poor grounding contact in the ABS hydraulic valve body; poor contact in the ABS hydraulic valve body wiring connector; ABS control unit malfunction. Solution: Loosen and retighten the hydraulic valve body's grounding screw, cleaning the contact surface if necessary; check if the connector gap has widened; replace the ABS or ABS/ASR control unit. Condition 4: ABS warning light turns on during high-speed driving. Cause: During high-speed driving, the ABS control unit detects a significant discrepancy between the rear and front wheel speed signals; incorrect tire or wheel rim specifications. Solution: Refer to the vehicle's tire and wheel rim specifications, often found on the label near the fuel tank cap. Condition 5: ABS warning light intermittently turns on. Cause: Improper adjustment of the brake light switch; poor internal contact in the brake light. Solution: With the engine running, press the brake pedal and use a finger to push the brake switch linkage down fully, then release the brake pedal to complete self-setting; replace the brake light switch if necessary. If the ABS warning light is on, it is advisable not to continue driving. An illuminated ABS light indicates a malfunction in the vehicle's anti-lock braking system. During emergency braking, if the wheels lock up, the vehicle may skid uncontrollably, preventing the driver from slowing down or adjusting the vehicle's trajectory, posing significant safety risks.
