What does the INSP warning light in a car mean?

INSP warning is set by car manufacturers to remind owners to perform maintenance at specified mileage intervals. After maintenance, the service reminder light can only be turned off by following a certain reset procedure. You can go to a 4S dealership to have it reset using a computer, or use the reset button on the instrument panel to complete the service reset. This indicator light is periodic and generally appears every 5,000-7,500 km. If the car has recently undergone maintenance or hasn't reached the next service mileage, it might be due to the system and can be manually reset. Car maintenance refers to the regular preventive work of inspecting, cleaning, replenishing, lubricating, adjusting, or replacing certain parts of the vehicle, also known as car servicing. Car maintenance mainly includes the engine system, transmission system, air conditioning system, cooling system, fuel system, power steering system, etc. Fluids that need regular replacement in a car include engine oil, transmission fluid, coolant, power steering fluid, brake fluid, etc. The purpose of car maintenance is to keep the vehicle clean, maintain normal technical conditions, eliminate potential hazards, prevent faults, slow down deterioration, and extend the service life. Minor maintenance generally refers to the routine service performed at the manufacturer's specified time or mileage to ensure vehicle performance. It mainly includes changing the engine oil and oil filter. The interval for minor maintenance depends on the effective time or mileage of the oil and oil filter used. Oil filters are generally divided into conventional and long-life types, with conventional filters being replaced along with the oil, while long-life filters last longer. Major maintenance refers to the routine service performed at the manufacturer's specified time or mileage, which includes changing the engine oil, oil filter, air filter, and fuel filter. Major maintenance builds upon minor maintenance, and these two types of services are usually performed alternately.

How Often Should the Santana Spark Plugs Be Replaced?

Under normal maintenance conditions, Santana spark plugs should be replaced every 40,000 to 60,000 kilometers. However, this may vary depending on the brand and engine type, so it is recommended to follow the user manual. You can refer to the following standards for maintenance and replacement: Platinum spark plugs should be replaced at 40,000 kilometers, ordinary nickel alloy spark plugs at 20,000 kilometers, and iridium spark plugs at 60,000 to 80,000 kilometers. Steps for replacing spark plugs: Open the hood, lift the plastic cover of the engine, and remove the high-voltage ignition wires. Mark each cylinder's position to avoid confusion. Use a spark plug socket to remove the spark plugs one by one. While removing them, check for any external debris like leaves or dust and ensure they are thoroughly cleaned. Place the new spark plugs into the spark plug holes, hand-tighten them a few turns, and then use the socket to tighten further. Reinstall the high-voltage ignition wires in the correct firing order, then secure the cover.

What engine is used in the Baojun 310?

The engine of the Baojun 310 is produced by SAIC-GM and belongs to a domestically manufactured four-cylinder naturally aspirated engine. The engine model of the Baojun 310 is LMH, with a maximum power of 59 kW, a maximum torque of 112 Nm, and a maximum horsepower of 80 Ps. For daily maintenance of the Baojun 310 engine, the following methods can be used: Use lubricating oil of appropriate quality grade. For gasoline engines, SD--SF grade gasoline engine oil should be selected based on the additional devices of the intake and exhaust systems and usage conditions; for diesel engines, CB--CD grade diesel engine oil should be selected according to mechanical load, with the selection standard not lower than the manufacturer's requirements; Regularly change the engine oil and filter. The quality of any grade of lubricating oil will change during use. After a certain mileage, performance deteriorates, which can cause various problems for the engine. To avoid faults, change the oil regularly according to usage conditions and keep the oil volume moderate; When engine oil passes through the fine holes of the filter, solid particles and viscous substances in the oil accumulate in the filter. If the filter is blocked and the oil cannot pass through the filter element, it will either burst the filter element or open the safety valve, allowing the oil to bypass through the bypass valve and bring contaminants back to the lubrication area, accelerating engine wear and increasing internal contamination; Regularly clean the crankcase. During engine operation, high-pressure unburned gases, acids, moisture, sulfur, and nitrogen oxides from the combustion chamber enter the crankcase through the gap between the piston rings and cylinder walls, mixing with metal powder from component wear to form sludge. A small amount remains suspended in the oil, while a large amount precipitates, clogging the filter and oil holes, making engine lubrication difficult and causing wear; Regularly use a radiator cleaner to clean the radiator. Removing rust and scale not only ensures the normal operation of the engine but also extends the overall lifespan of the radiator and engine.

What is the normal temperature of coolant?

The normal temperature is indicated when the needle points to 90°C at the center of the gauge. After starting the vehicle, the antifreeze temperature rises rapidly. Once the needle reaches the central position, the heat exchange reaches equilibrium and the antifreeze temperature stabilizes. Generally, it's optimal to start driving when the temperature reaches the middle position. More information about coolant is as follows: 1. Introduction: Its full name should be antifreeze coolant, meaning it has antifreeze functionality. Antifreeze prevents the coolant from freezing and cracking the radiator or damaging the engine cylinder block during cold seasons when the vehicle is parked. However, it's important to correct a common misconception: antifreeze is not just for winter use; it should be used year-round. In regular vehicle maintenance, the engine antifreeze should be replaced every year. 2. Function: Automotive coolant is used to regulate the engine's temperature. If the temperature is too high, the engine cannot operate within its normal temperature range. Moving parts may expand due to heat, disrupting normal clearance tolerances, and lubricants may burn, degrade, or lose viscosity due to high temperatures, leading to seized components or accelerated wear. The normal operating temperature should be around 90°C; temperatures significantly higher or lower can cause damage to the vehicle.
