How to Tell if an Engine Has Been Disassembled?

Can spark plugs with different thread lengths be used?

Spark plugs with different thread lengths cannot be used because mismatched models and varying discharge gaps can cause issues such as engine shaking, difficulty in acceleration, and increased fuel consumption. Steps for replacing spark plugs: Open the hood, lift the engine's plastic cover, remove the high-voltage distributor wires, and 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 external debris like leaves or dust and ensure thorough cleaning. Place the new spark plug into the spark plug hole, hand-tighten it a few turns, and then use the socket to tighten it further. Reinstall the removed high-voltage distributor wires according to the firing order and reattach the cover. Damaged spark plugs can directly lead to issues like ignition system leakage, increased fuel consumption, reduced power, and most importantly, difficulty in starting the engine, affecting normal vehicle operation. Severe spark plug erosion—such as scarring at the top, broken or melted electrodes—indicates that the spark plug is damaged and should be replaced.

What to Do if the Tire Tread is Cut?

Tire tread cuts can be minor or severe. If the cut is minor, the tire can still be used normally. However, if the cut is severe, it is recommended to replace the tire or have it repaired before further use. If the damaged area is particularly large, repairs may not be effective, and there could be safety risks, so immediate replacement is advised. Here are the details: 1. Immediate Replacement: If the tread groove is cut by 4mm, the tire should be replaced immediately. Although the tread is thicker than the sidewall, the total thickness of the tire tread is only 13mm, with 7mm for the tread depth and 6mm for the crown. A 4mm cut in the groove means the remaining thickness is only 2mm, which poses a safety hazard, so replacement is recommended. 2. Remove Debris: To minimize the risk of tread cuts, regularly remove small stones lodged in the tire tread. Sharp stones in the tread grooves are the main cause of tread cuts. Additionally, trapped stones increase road noise, reduce the tire's drainage and grip performance, and extend braking distances, increasing the risk of hydroplaning in wet conditions.

How Long Can a Car Drive Continuously?

A car can drive continuously for 500-800 kilometers as long as there is fuel in the tank. Generally, engines undergo a 500-hour non-stop test. However, the driving range may vary depending on the vehicle. Precautions for long-distance driving: Check the engine oil, transmission fluid, clutch fluid, power steering fluid, brake fluid, coolant, and windshield washer fluid, and top up or replace them if necessary. Inspect for leaks in oil pipes, water pipes, and seals, and check rubber hoses for aging, cracking, or wear. Examine all component connections for looseness and repair or replace as needed. Check the battery display window for voltage status, ensure the battery is securely fastened, and inspect terminals for looseness or corrosion. Charge, tighten, or rinse the positive and negative terminals with hot water as required. Monitor all warning and indicator lights on the dashboard, as well as all vehicle lights, and address any malfunctions accordingly. Inspect tire tread wear, check for foreign objects in the tread, examine the tire surface and sidewalls for damage, and ensure all tire pressures are normal. Perform preventive replacement or maintenance as needed.

What is the mantra for short individuals in Subject 2?

Here is the mantra for short individuals in Subject 2: 1. Adjust the seat after getting in the car, ensuring the height and position are suitable: Adjust the rearview mirror to clearly see the ground behind the wheels; fasten the seatbelt and listen carefully to instructions and commands; identify the garage number and locate the side line at 1.5 meters; stop at the sensor line and ensure the garage direction is correct. 2. First find the garage when parking, and don’t confuse the left and right directions; look at the reverse mirror when shifting to reverse gear, and don’t stop the car after crossing the line twice; check the car body in the reverse mirror, and quickly turn the wheel back when the garage entrance is more than half passed; look back at the garage corner, and steer toward the wider side; check if the car is straight, ensuring both side lines are parallel. 3. Straighten the wheel after parallel parking, and make sure the number of steering wheel turns is correct; stop the car when it’s straight and the reverse mirror crosses the line; pause in the garage for three seconds, and carefully consider left and right when exiting; maintain a distance of 30 cm for parallel parking, which is most suitable.
