Is it okay to only replace the front tires with winter tires?

Winter tires should not be replaced only on the front wheels. Correct practice: All four tires should be replaced with winter tires of the same specification, brand, structure, and tread pattern. Consequences of replacing only two tires: If only two winter tires are installed, the following situations may occur: Installing winter tires only on the front wheels will result in insufficient grip on the rear wheels, making the vehicle prone to oversteering or brake-induced skidding when driving on winter roads. Installing winter tires only on the rear wheels will lead to insufficient grip on the front wheels, causing steering issues when driving on winter roads. Therefore, it is recommended to replace all four winter tires at the same time, ensuring that tires on the same axle are of the same specification, brand, structure, and tread pattern.

What is the engine model of the Soueast DX7?

The engine model of the Soueast DX7 is the 4A91-turbo engine, with a maximum power of 145KW, maximum horsepower of 197, and maximum torque of 285Nm. The engine of the Soueast DX7 is produced by Shenyang Aerospace Mitsubishi and is a domestically manufactured engine. For daily maintenance of the Soueast DX7 engine, the following methods can be used: Use lubricating oil of the appropriate quality grade. For gasoline engines, select SD--SF grade gasoline engine oil based on the additional equipment of the intake and exhaust systems and usage conditions; for diesel engines, choose CB--CD grade diesel engine oil according to mechanical load, with the selection standard being no lower than the manufacturer's specified requirements. Regularly change the engine oil and filter. The quality of any grade of lubricating oil will deteriorate during use. After a certain mileage, performance degradation can cause various problems for the engine. To avoid malfunctions, change the oil regularly based on usage conditions and maintain an appropriate oil level. When oil passes through the fine pores of the filter, solid particles and viscous substances in the oil accumulate in the filter. If the filter becomes clogged and oil cannot pass through, the filter element may burst or the safety valve may open, allowing oil to bypass through the bypass valve and carry contaminants back to the lubrication areas, 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 particles from component wear to form sludge. Small amounts remain suspended in the oil, while larger amounts precipitate out, clogging filters and oil passages, making engine lubrication difficult and causing wear. Regularly use a radiator cleaner to flush the radiator. Removing rust and scale deposits not only ensures normal engine operation but also extends the overall lifespan of the radiator and engine.

What does EFI vehicle mean?

EFI vehicle refers to a vehicle equipped with an electronic control fuel injection system, which is the abbreviation for 'electronic control gasoline injection engine'. Advantages of EFI vehicles: The electronic control fuel injection system uses micro integrated circuits to control the fuel injection quantity based on various operating conditions of the vehicle and engine, promoting complete combustion of fuel in the engine, thereby significantly reducing exhaust pollution. Generally speaking, EFI vehicles have performance advantages such as higher power, fuel efficiency, lower noise, and higher one-time ignition rate compared to carburetor vehicles. Difference between EFI and carburetor engines: EFI engines are significantly different from carburetor engines, and there are notable differences in operating methods as well. When starting an EFI engine (including cold starts), it is generally unnecessary to press the accelerator.

Is U-turn allowed at traffic light intersections?

Generally speaking, on the left-turn lane at a traffic light intersection, U-turns are allowed if there is no sign prohibiting U-turns. U-turn rules at traffic lights: At intersections with U-turn traffic lights or traffic signs indicating U-turn lanes on the roadway, U-turns are permitted when safety is confirmed. At intersections without U-turn lights but with left-turn lights, U-turns are allowed. Drivers can make U-turns using the left-turn lane at the central median or when approaching the intersection, provided it does not affect normal traffic flow. Yellow grid areas: Although parking is prohibited in yellow grid areas, if the traffic light ahead is red, vehicles behind should reasonably avoid stopping in this area. The U-turn operation can be completed at the central guardrail. Crosswalk areas: U-turns are not allowed on pedestrian crosswalks. Drivers can make a U-turn after crossing the crosswalk when the light is green, but must never make a U-turn directly on the crosswalk.

How Long Does It Take from Vehicle Production Scheduling to Delivery?

It typically takes about half a month from vehicle production scheduling to delivery. There are three key points to note during new car inspection: 1. Check the paint surface: Pay special attention to the uniformity and smoothness of the seams. It’s best to compare two vehicles of the same model. The gaps between doors, bumpers, and the engine hood should be consistent. If the gaps are too wide or differ from other vehicles, choose carefully; 2. Check the tires: The tire walls of a new car should be free of any damage, with no nail puncture marks on the front tire walls. Ideally, the tire hairs should still be intact, at least visible on the rear tires. If no tire hairs are visible on either front or rear tires, but the odometer shows only a few kilometers, this is abnormal; 3. Check the nameplate: Each vehicle’s nameplate corresponds to a unique engine number and chassis number. Verify these numbers against the certification codes to ensure consistency. Also, check the manufacturing date on the nameplate. The gap between the delivery date and the manufacturing date should not exceed three months.

What Causes Front Wheel Noise at Low Speeds on Flat Roads?

It could be caused by loose components or damaged/deformed parts in the left front section. Here are other possible causes: Foreign Object Accumulation: Excessive debris buildup on the fender liner or sound insulation pad. When turning, the tire interferes with these objects, producing abnormal noise. Cleaning the fender liner typically eliminates the noise. Screw Loosening: Missing fastening screws for the fender liner or sound insulation pad may cause these components to lift. During turns, the front wheel rubs against them, creating noise. Inspect and tighten all fender liner and insulation pad fasteners to eliminate looseness or lifting issues. Unauthorized Modifications: Installing non-OEM sized tires (e.g., wider tread or larger diameter) may cause tire-body interference during turns, generating noise. This poses significant safety risks. Revert to factory-specified tire dimensions immediately.
