Is It Necessary to Use OEM Thermostats?

It is recommended to use OEM parts as thermostat assemblies generally do not fail easily. More information about thermostats is provided below: 1. Maintain good working condition: The thermostat must remain in good working condition; otherwise, it can severely affect the engine's normal operation. For example, if the thermostat opens (referring to the main valve) too late or fails to open, it can cause engine overheating. Conversely, if it opens too early, the engine's warm-up time will be prolonged, resulting in the engine running too cold. 2. Working principle: Under normal circumstances, when the engine is started cold, the operating temperature is very low. To allow the temperature to rise quickly, the thermostat controls the coolant flow (with the main valve closed), directing the coolant pumped by the water pump into the bypass pipe, bypassing the radiator—this is known as the small circulation. Once the coolant temperature reaches 87°C, the thermostat valve opens, allowing the coolant to flow through the radiator, transitioning the cooling system into the large circulation. Typically, within about five minutes after a cold start, the coolant temperature should reach the normal operating range of 85–105°C. If the engine takes too long to reach the normal operating temperature or if the temperature rapidly exceeds 110°C, it may indicate a thermostat malfunction.

How Heavy is a Sedan?

Models vary, and so does the weight of the car. Generally, family economy sedans with engine displacements between 1.1 to 1.6L have a total vehicle weight of approximately 1.1 to 1.4 tons; mid-to-high-end cars with engine displacements ranging from 1.8 to 4.0L have a total vehicle weight of about 1.8 to 3.5 tons. Related information: 1. Vehicle weight parameters: The curb weight of a car, previously commonly referred to as the 'empty weight.' The curb weight of a car refers to the weight of the vehicle when fully equipped according to the manufacturer's technical conditions (such as spare tires, tools, etc., all installed) and with all fluids filled. This is an important design indicator for cars. 2. Expansion: This indicator must be both advanced and feasible. It is closely related to the car's design level, manufacturing level, and industrialization level. Under the same model conditions, the better the design method, the superior the production level, and the higher the industrialization level, the lower the curb weight will be.

Can You Stop During the Second Driving Test?

You can stop during the second driving test. Here is a detailed introduction about the second driving test: 1. Overview: The second driving test, also known as the small road test, is part of the motor vehicle driver's license assessment and is referred to as the field driving skill test. The test items for cars C1 and C2 include five mandatory contents: reversing into a garage, parallel parking, stopping and starting on a slope, turning at a right angle, and driving on a curve. 2. Others: If you fail the second driving test for the first time, you can retake it once. If you do not participate in the retest or still fail the retest, the test will be terminated, and the applicant should reschedule the test after ten days. During the validity period of the driving skill test permit, the number of scheduled tests for the second driving test and the third road driving skill test should not exceed five times.

Will making a mistake in the lighting test result in immediate failure in Subject 3?

Making one mistake in the lighting test of Subject 3 results in a deduction of 100 points, leading to immediate failure and requiring a retake. Below is a detailed introduction to the Subject 3 examination: 1. Overview: Subject 3, which includes the road driving skills test and the safety and civilized driving knowledge test, is part of the motor vehicle driver's license assessment. It is the abbreviation for the road driving skills and safety and civilized driving knowledge test subjects in the motor vehicle driver's examination. The content of the road driving skills test varies depending on the type of vehicle being licensed. 2. Test Content: The road driving skills test of Subject 3 generally includes: preparation before getting on the car, lighting simulation test, starting, driving in a straight line, shifting gears, changing lanes, parking by the roadside, going straight through intersections, turning left at intersections, turning right at intersections, passing through pedestrian crossings, passing through school zones, passing through bus stops, meeting other vehicles, etc.

What are the reasons for tires being extremely hot to the touch?

The reasons for tires being extremely hot to the touch are poor heat resistance of the tires themselves and some external factors causing excessive tire temperature. The following are related explanations: 1. Tire heat dissipation: When driving in hot summer or at high speeds, the temperature of the tires rises quickly, and the internal pressure of the tires also increases accordingly. When the tire temperature reaches a balance between heat absorption and dissipation, the temperature and pressure of the tires will not increase further, and correct methods should be used to dissipate heat from the car tires. 2. Different heat resistance levels: Different types of tires have different heat resistance levels. Under normal circumstances, the maximum temperature that household car tires can withstand is around 180 to 220 degrees Celsius. During normal driving, the temperature of the tires is maintained at around 90 to 110 degrees Celsius.

Can You Press the Clutch When Going Downhill in a Manual Transmission Car?

When going downhill in a manual transmission car, you should not press the clutch pedal and brake pedal simultaneously. The clutch is typically operated when starting the engine, moving the vehicle from a standstill, or shifting gears. When descending a slope, multiple factors come into play, and the clutch should only be used for shifting gears, starting, or changing gears while driving. If you press the clutch unnecessarily, it can cause significant damage to the clutch mechanism. Hazards of Pressing the Clutch When Going Downhill in a Manual Transmission Car: If you fully depress the clutch while going downhill, it is equivalent to coasting in neutral. In this state, the gear is in neutral, and the downhill speed in neutral is much faster compared to when not in neutral. If the vehicle's braking system fails, the driver may lose control of the car. However, if the car is in gear without pressing the clutch, the speed is regulated by the engine's mechanism, effectively using the engine as a brake, which helps reduce the vehicle's speed. Function of the Clutch: The clutch's role is to transmit or cut off the engine's power. In a manual transmission car, once a gear is engaged, the engine can drive the wheels, and the wheels can also drive the engine. Since the engine's speed is fixed, the wheels cannot make the engine rotate faster when going downhill, thereby creating an engine braking effect.
