What Causes High Engine Temperature?

Here are several common causes of engine overheating: 1. Insufficient coolant leading to high temperature: Coolant deficiency is the easiest to identify—simply open the engine hood and check the coolant level. If the coolant level is below the "MIN" mark, it indicates insufficient coolant. 2. Dirty radiator causing temperature rise: If the engine compartment accumulates excessive dust due to long-term lack of cleaning, it can lead to poor heat dissipation in the radiator, resulting in high engine temperature. Generally, overheating caused by excessive dust on the radiator can be resolved by simply cleaning the dust off the radiator. 3. Thermostat malfunction causing temperature rise: The thermostat's function is to automatically adjust the amount of water entering the radiator based on the coolant temperature, altering the water circulation range to regulate the cooling system's heat dissipation capacity, ensuring the engine operates within the appropriate temperature range. If high temperature is noticed during normal driving, open the engine hood and touch the radiator's inlet and outlet pipes to check for a temperature difference. If a temperature difference exists, it indicates a faulty thermostat that cannot function properly, leading to high engine temperature. 4. Electric fan malfunction causing temperature rise: Fan failure is another cause of engine overheating. A non-operational fan leads to insufficient radiator cooling, causing high engine temperature. There are many reasons for fan failure, including fan motor malfunction, thermostat failure, or a blown fan fuse, all of which can prevent the fan from operating.

What is the sound when hitting the radar?

Radar emits a continuous beep when hitting an obstacle. Here are the relevant details: 1. Reversing Radar: The reversing radar, also known as "reverse anti-collision radar" or "parking assist device", mainly consists of ultrasonic sensors, a controller, and a display. 2. Working Principle: When reversing, the reversing radar uses the ultrasonic principle. The probe installed on the rear bumper sends ultrasonic waves that reflect off obstacles, calculates the actual distance between the vehicle body and the obstacle, and then alerts the driver, making parking or reversing easier and safer.

Which institutions can inspect used cars?

Seek independent third-party vehicle inspection institutions with nationwide chains for more reliable results. Below are methods to check if a used car has been in an accident: 1. Check the glass production date: Normally, glass isn't replaced, so checking its production date can be telling. The date is usually in a format of numbers + dots, where numbers represent the year and dots represent the month. 2. Examine the wear on the frame: If the car has been in a major accident, the body frame will show varying degrees of dents and misalignment, so assessing the frame's condition can indicate past accidents. 3. Inspect the screws: Look at the screws on the hood, radiator support, and door connections. If any of these screws show abnormalities, it's a strong indication the car was in a major accident. 4. Review maintenance records: Check the maintenance records at authorized dealerships (4S shops). Any accident repairs done at a 4S shop will be systematically recorded.

Standard Values for Intake Air Temperature Sensor?

Under normal conditions, the resistance is approximately 2-3 kiloohms at 20°C and about 0.4-0.7 kiloohms at 80°C. If the measured values do not meet the specified requirements, the sensor should be replaced. When the intake air temperature sensor installed inside the air flow sensor is damaged, the air flow sensor should be replaced. Below is additional information about the intake air temperature sensor: 1. Function: The intake air temperature sensor is essentially a negative temperature coefficient thermistor. Its role is to transmit the intake air temperature to the ECU in the form of a voltage signal, which the ECU then uses as a correction signal for fuel injection and ignition. 2. Location: The intake air temperature sensor is typically installed in the intake pipe or within the air flow meter. 3. Damage Consequences: If the engine's intake air temperature sensor is damaged, the ECU not only fails to accurately use it as a correction signal for fuel injection and ignition but may also receive incorrect information, leading to issues such as difficulty starting the engine, unstable idle speed, and increased exhaust emissions.

How to Adjust Rearview Mirrors for Subject 2 Driving Test?

Here is the relevant introduction on adjusting rearview mirrors for Subject 2 driving test: 1. Reverse Parking: During reverse parking training, when moving the vehicle left backward, focus mainly on the left mirror; when moving right backward, focus on the right mirror. Adjusting the rearview mirrors vertically allows you to clearly see the position of points and lines on the ground, serving as a reference during training. Therefore, adjust the mirrors vertically until you can see the rear wheels or even the contact point between the rear wheels and the ground. Adjusting the mirrors horizontally affects the breadth of your field of vision, helping you make early judgments during training. Hence, adjust the mirrors horizontally until you can see the rear of the car or even the rear corners of the garage. 2. Hill Start: When going uphill, maintain a 30cm distance between the car body and the right roadside line. Adjust the right mirror downward until you can clearly see the wheels and the right roadside line. 3. Right-angle Turn: When approaching a right-angle turn, if it's a left turn, stay close to the right roadside line. Adjust the right mirror outward and downward until you can clearly see the distance between the car body and the roadside line. During the turn, maintain a 10cm distance between the car body and the right line, which is the optimal distance for a right-angle right turn. The same principle applies to right turns. 4. Curve Driving: During curve driving, rearview mirrors serve as excellent auxiliary references. Adjust both mirrors maximally downward and inward to clearly observe the distance between the rear wheels and the S-curve line, allowing timely adjustments in direction and speed. 5. Parallel Parking: Parallel parking involves frequent use of both side mirrors. Taking right parallel parking as an example, before parking, ensure the wheels are about 10cm from the roadside line. When the rear wheels are about to reach the front line of the parking space, turn the steering wheel fully to the right. Both steps require the right mirror to clearly see the rear wheels and the roadside line. The next steps involve looking at the inner corner of the parking space to straighten the steering wheel and observing when the left rear wheel touches the outer line of the parking space to turn the steering wheel fully right for parking. Both steps require the left mirror, which should be slightly more outward compared to the right mirror to ensure the inner corner of the parking space is visible immediately.
