Car engine cooling slow reasons are as follows: Radiator core tube blockage: When the coolant temperature is normal at low engine speeds but rises sharply at high speeds, the radiator should be checked for blockages. The causes of radiator blockage, apart from impurities in the original coolant, include mixing different brands of coolant, which can produce white crystals that easily clog the narrow water channels in the radiator, hindering the cooling system circulation and causing the engine coolant temperature to rise excessively. Radiator leakage: Depending on the location and severity of the leak in the radiator core tube, different repair methods can be applied, or the radiator core tube may need to be replaced if necessary.

Can I Schedule the Subject Three Test Immediately After Passing Subject Two?

You cannot schedule the Subject Three test immediately after passing Subject Two. The relevant explanations are as follows: 1. Scheduling time for Subject Three: The scheduling of Subject Three is essentially unrelated to when Subject Two was passed, but rather depends on the passing date of Subject One. You can schedule Subject Three 30 days after passing Subject One. 2. Hour restrictions: Scheduling Subject Three is subject to hour requirements. For example, for a C1/C2 driver's license, you need to complete at least 22 training hours before scheduling Subject Three. Typically, these hours for Subject Three start counting only after passing Subject Two, with a maximum of 4 hours credited per day as per regulations.

Should the turn signal be turned off when pulling over to the side in Subject Three?

When pulling over to the side in Subject Three, the right turn signal needs to be turned off. The relevant explanations are as follows: 1. Operational requirements for pulling over: When pulling over, first decelerate and steer to the right, turn on the right turn signal while applying the brake to slow down the vehicle, depress the clutch to bring the vehicle to a complete stop. If there is a designated parking area, the vehicle must be parked within it; if there is no parking area, the vehicle must be parked within 30 centimeters of the roadside. First engage the handbrake, then shift into gear, then release the brake and turn off the turn signal to complete the parking. 2. Precautions: There are many lighting operations in the Subject Three exam. During the exam, it is essential to clearly listen to the examiner's instructions and avoid excessive nervousness, as lighting errors will result in the need to retake Subject Three.

Why did the car's rearview mirror suddenly stop retracting automatically?

This is most likely because the rearview mirror knob was not rotated to the "AUTO" position when adjusting the mirror, or the option "Automatically fold rearview mirrors when locking the car" was not selected in the central control system. Here is some additional information: 1. Rearview mirror folding function: The rearview mirror folding function refers to the ability of the rearview mirrors on both sides of the car to fold and retract when necessary. Rearview mirrors with this function can be retracted when passing through narrow sections, improving the vehicle's passability. When the driver leaves the car, the rearview mirrors can also be folded, not only protecting the mirror surface but also reducing parking space and effectively avoiding scratches. 2. Circuit issues: The failure of the rearview mirror to fold automatically could be due to a circuit problem, which requires inspection by a professional repair facility and is generally beyond the owner's ability to handle. You can also check if the rearview mirror folding mechanism is blocked by any foreign objects, as this can also cause the folding function to fail.
