At what point does a cracked tire require replacement? This three-point guide explains it all at once.
Check tire pressure monthly at room temperature. If it's below the normal limit, refill it immediately. Avoid excessively high or low pressure, as this can affect driving safety. Inspect tires for cracks and replace them if any safety hazards are present. When choosing tires, ensure they are of the same model.
Second, battery maintenance and inspection.
Check that the battery is securely fastened and that the electrolyte level is between the upper and lower limits. If it approaches the lower limit, add electrolyte or distilled water to the upper limit. Maintain good contact between the positive and negative battery cables and keep the battery clean and dry. For vehicles that have been stored for an extended period, remove the positive and negative battery cables and reconnect them about two weeks apart. Start the engine for about 20 minutes. If the charge is significantly low, recharge it immediately.
Third, check the clutch master cylinder fluid level.
If the clutch fluid level is between the upper and lower limits, it's normal. If it's below the standard, the master cylinder or slave cylinder cup may be damaged. If you experience difficulty or inability to shift gears while the engine is running, please visit a nearby service station immediately for inspection.
Fourth, Checking the Brake Fluid Level
If the brake fluid level is between the high and low levels, it's normal. If the brake fluid level is close to or below the lower limit, there may be a leak in the system or excessive brake shoe wear. Visit a service station for inspection immediately. When adding brake fluid, be sure to use the same type of fluid to prevent damage to the brake cups. Also, be sure to protect the paint from corrosion.
Fifth, Checking the Engine Coolant Level
Never open the radiator cap while the engine is hot; otherwise, you may be burned by splashing coolant or hot steam. After the engine cools, check the coolant level. It should be between the full and low levels. If it is below the full level, add distilled water, purified water, or refrigerant. The level should not exceed the full level. If the coolant level decreases rapidly within a short period of time, check the cooling system for leaks or visit a service station for inspection.
