How often should Evans Waterless Coolant be replaced?

Determining whether coolant has deteriorated is not simply a matter of observing color changes with the naked eye or estimating based on time. The correct method requires professional instrument measurement, which is generally available at authorized 4S shops or auto repair shops. Below are the relevant steps: Check for leaks: Open the cooled engine cover and first inspect the cooling system pipelines, joints, etc., for any signs of leakage, and clean the relevant parts. Drain and clean: Drain the existing water or water-based coolant from the radiator into a shallow basin or bucket, observing whether it is clear, transparent, and free of impurities. If it is generally acceptable, rinse the cooling system twice with clean water.

Can ABS Cause Side Slip When Steering During Emergency Braking?

ABS does not cause side slip when steering during emergency braking. This is because ABS prevents the wheels from locking up during emergency braking, allowing the vehicle to maintain good directional stability even under hard braking. How ABS Works: During braking, ABS quickly determines the wheel lock-up status based on speed signals from each wheel speed sensor. It closes the normally open input solenoid valve for wheels that begin to lock, keeping the braking force constant. If the wheel continues to lock, the normally closed output solenoid valve opens, causing the braking pressure on that wheel to drop rapidly as it connects directly to the brake fluid reservoir, preventing complete wheel lock-up due to excessive braking force. This keeps the braking state at the optimal point (20% slip ratio S), achieving the best braking performance and maximum driving safety. Functions of ABS: Maximizes brake efficiency, reducing braking time and distance. Effectively prevents vehicle side slip and fishtailing during emergency braking, ensuring excellent driving stability. Allows steering during emergency braking, providing good steering control. Avoids severe friction between tires and the road surface, reducing tire wear.

What Do 9-Speed Tiptronic and 7-Speed Dual Clutch Mean?

Here is the related introduction about 9-speed tiptronic and 7-speed dual clutch: Different gear forms: The 7-speed dual clutch transmission adopts a manual gearbox, cooperating with an electronic control computer to simulate the automatic transmission operation mode; while the 9-speed tiptronic transmission is an automatic transmission, using computer control to simulate the manual mode. Different clutch forms: The 7-speed dual clutch transmission uses wet dual clutch plates, which alternately work for gear shifting, while the 9-speed tiptronic transmission uses a wet clutch plate group to control the gear combination operation of the transmission. Different fuel-saving capabilities: The 7-speed dual clutch transmission actually uses the gear set of a manual transmission, with no power loss, naturally improving fuel economy, while the 9-speed tiptronic is an automatic transmission, where the hydraulic torque converter still loses engine power, and even with the addition of a mechanical lock-up system, it will still increase fuel consumption at low speeds.

What is the difference between 400cc and 200cc?

Motorcycle 200cc and 400cc have the following differences: Different displacement: Motorcycle 200cc means a displacement of 200 milliliters; while motorcycle 400cc means a displacement of 400 milliliters. Different engine power: The power of a 200cc motorcycle is smaller; while the power of a 400cc motorcycle is larger. Different power: The power of a 200cc motorcycle is smaller; while the power of a 400cc motorcycle is larger. In terms of power and acceleration, the 400cc is much stronger than the 200cc. As for the difference between water-cooled and air-cooled engines, it lies in the control of engine temperature. Different fuel consumption: The fuel consumption of a 200cc motorcycle is less; while the fuel consumption of a 400cc motorcycle is more.

When changing tires, is clockwise tightening or loosening the bolts?

When changing tires, loosening the bolts is counterclockwise, and tightening the bolts is clockwise. When installing tire nuts, the tightening is not determined by depth but by torque. Different specifications and grades of bolts and nuts have specified torque range values. Simply tighten according to the bolt's grade, and the vehicle can operate normally. Torque is a special type of moment that causes an object to rotate. Engine torque refers to the moment output from the crankshaft end of the engine. Under fixed power conditions, it is inversely proportional to the engine speed—the faster the speed, the smaller the torque, and vice versa. It reflects the vehicle's load capacity within a certain range. External torque is called torque or external couple moment, while internal torque is called internal couple moment or torque. Any brand of tire will have a wear indicator at the bottom of the tread grooves. Generally, the wear indicator height for passenger car tires is 1.6 millimeters (this height is also the legally mandated minimum groove depth), while for heavy-duty tires, it is 2.4 millimeters. During daily vehicle use, tires may be punctured by foreign objects, leading to damage. Tire damage includes tread cracks, tread bulges, missing tread rubber, severe sidewall wear, and repeated punctures by foreign objects. Especially with bulges, there is a constant risk of tire blowout. If tire damage is detected, the owner should promptly take the vehicle to a professional tire shop for inspection and replacement if necessary. The typical lifespan of a tire is around 5 years. Beyond this period, the tire begins to age. The main signs of tire aging are surface hardening followed by cracking. Aged tires lose their elasticity, and continued use can lead to tread deformation, increasing the risk of a blowout.

Is ABS Made of Plastic?

ABS is not a plastic material; ABS material is a thermoplastic polymer structural material, which is very safe for industrial use. How ABS Works: During braking, ABS quickly determines the wheel lock-up state based on the speed signals from each wheel speed sensor, closes the normally open input solenoid valve for the wheel that starts to lock up, and keeps the braking force unchanged. If the wheel continues to lock up, the normally closed output solenoid valve is opened, causing the braking pressure on that wheel to drop rapidly due to the direct connection to the brake fluid reservoir, preventing the wheel from completely locking up due to excessive braking force. This keeps the braking state at the optimal point (slip ratio S of 20%), ensuring the best braking performance and the highest driving safety. The Role of ABS: It maximizes the effectiveness of the brakes, reducing braking time and distance. It effectively prevents vehicle skidding and fishtailing during emergency braking, ensuring good driving stability. It allows steering during emergency braking, providing good steering control. It avoids severe friction between the tires and the ground, reducing tire wear.
