Engine suddenly overheating causes are: 1. The fan motor is not working or the fan clutch is faulty, preventing normal cooling; 2. The three-way catalytic converter is blocked or the pipe is broken, causing exhaust obstruction and leading to engine overheating; 3. The cooling system pipe is broken, causing coolant loss and preventing the heat dissipation from functioning normally; 4. The water pump, after long-term use, has highly worn parts that have fallen off; 5. Excessive scale deposits on the outer wall of the cylinder liner, preventing the heat generated by the cylinder from being transferred to the cooling water. The methods to deal with sudden engine overheating are: 1. Repair the fan motor and fan clutch; 2. Clean the scale on the outer wall of the cylinder liner; 3. Add cooling water; 4. Replace the three-way catalytic converter.

What does tire aspect ratio mean?

Aspect ratio refers to the ratio of the height from the rim to the tread to the maximum measured width of the tire's cross-section, expressed as a percentage, i.e., the height as a percentage of the width. Taking a tire with the specification 205/60R15 as an example, the maximum width of its cross-section is 205 millimeters, the inner diameter is 15 inches, and the aspect ratio is 60. Additional information: 1. Pros and cons of high aspect ratio tires: High aspect ratio tires have longer sidewalls and stronger cushioning capabilities, offering relatively higher comfort. However, they provide poorer feedback on road conditions and weaker lateral resistance during cornering. 2. Pros and cons of low aspect ratio tires: Low aspect ratio tires have shorter sidewalls and wider treads, allowing them to withstand greater pressure, offer more sensitive road feedback, and better handling. Moreover, low aspect ratio tires can provide a more intense visual impact, enhancing the overall premium feel of the vehicle.
