Here is a detailed introduction about ILSAC engine oil: 1. ILSAC stands for the International Lubricant Standardization and Approval Committee. ILSAC is a certification system for engine oil jointly established by AAMA and JAMA (American and Japanese Automobile Manufacturers Associations). The purpose of ILSAC is to enhance fuel-saving performance based on various oil performance metrics. GF5 oil is actually an abbreviation for ILSAC GF5. 2. The role of engine oil. Engine oil not only lubricates the engine but also performs functions such as cleaning, sealing, buffering, rust prevention, and heat dissipation. During engine operation, engine oil forms a thin film on the surfaces of various engine components, preventing direct contact and friction between these parts.

What Causes the Friction Sound When Turning the Steering Wheel?

When turning the steering wheel, a rubber friction sound is usually caused by the relative movement between the dust cover at the bottom of the steering column and the steering column itself. There are three solutions to this issue. Friction Between the Steering Column and Floor Mat: If the installed floor mat is too large and comes into direct contact with the steering column, friction will occur as the steering column rotates. Lack of lubrication can lead to a friction sound. The solution is to apply lubricant. Faulty Clock Spring: If the sound originates from inside the steering wheel, it is often due to interference from the clock spring inside the steering wheel. The solution is to lubricate or replace the clock spring. Lack of Lubrication in the Strut Mount Bearing: If the abnormal sound comes from outside the vehicle when turning the steering wheel, it might be due to insufficient lubrication in the strut mount bearing. The solution is to lubricate or replace the strut mount bearing.

How to Reverse Park into a Garage?

Align the left headlight of the car with the garage line or turn the steering wheel fully to the right if using the right-side vehicle approach. When the left headlight aligns with the garage line, turn the steering wheel fully to the left and continue moving forward slowly. Once you can see the complete front of the rear vehicle in the left rearview mirror, straighten the steering wheel and start reversing slowly. When the left rear wheel touches the line or the front of the car is parallel with the rear of the vehicle in front, turn the steering wheel fully to the left and start reversing slowly, making minor adjustments to park smoothly.

What is the purpose of the fault indicator lights on the Foton Aumark dashboard?

When the engine coolant temperature warning light appears on the dashboard, it indicates that the engine coolant temperature is too high and there is a malfunction. If the brake warning light illuminates, it may indicate that the brake pads have worn to their limit, there is insufficient brake fluid, or there is a circuit short. When the ABS warning light comes on, you should also be cautious about the vehicle's braking system and check for any issues.

Which One is the Clutch, Brake, and Accelerator in a Manual Transmission?

In a manual transmission car, the accelerator and brake are located at the bottom of the left side of the driver's compartment. The leftmost pedal is the clutch, the middle one is the brake, and the rightmost one is the accelerator. Introduction to Manual Transmission: A car that uses a manual shift mechanical transmission (also known as manual transmission, MT) to adjust speed. That is, the gearshift lever must be manually moved to change the gear meshing position inside the transmission, altering the gear ratio to achieve speed change. The gearshift lever can only be moved when the clutch is depressed. Manual Transmission: Simple in structure, reliable in performance, and low in manufacturing and maintenance costs. It also has high transmission efficiency (theoretically more fuel-efficient). Additionally, due to pure mechanical control, it has fast gearshift response and can more directly reflect the driver's intention, thus offering more driving pleasure.
