How to Determine Thermostat Failure?

Methods to determine thermostat failure are as follows: 1. Open the filler cap of the coolant reservoir and observe if there is any water flow inside. If not, it indicates that the thermostat is damaged or there is debris stuck between the main valve switch. 2. Remove the thermostat from the vehicle and place it in boiling water to observe if it opens as the water temperature rises. 3. Start the engine and after 3 minutes, feel the upper and lower radiator hoses. If the thermostat is functioning properly, the upper and lower hoses will have different temperatures—typically, the upper hose will be hot and the lower hose will be cool. The thermostat is a valve that controls the flow path of the coolant, serving as an automatic temperature-regulating device. It usually contains a temperature-sensitive component that opens or closes the flow of air, gas, or liquid through thermal expansion or contraction.

What is the principle of the clutch?

Clutch works as follows: The torque generated by the engine is transmitted to the driven plate through the friction between the flywheel, pressure plate, and the contact surface of the driven plate. When the driver depresses the clutch pedal, the diaphragm spring's large end moves the pressure plate backward through mechanical transmission, separating the driven part from the driving part. During vehicle operation, the driver can depress or release the clutch pedal as needed to temporarily disconnect or gradually engage the engine with the transmission, thereby cutting off or transmitting the engine's power to the transmission. The clutch is a common component in mechanical transmission systems, allowing the drivetrain to be disconnected or engaged at any time.

Can the 'Study to Reduce Points' Program Be Used to Deduct Points from Parents' Driver's Licenses?

The 'Study to Reduce Points' program cannot be used to deduct points from parents' driver's licenses; learners can only reduce points on their own driver's licenses. Within one scoring cycle, a maximum of 6 points can be reduced. There are three ways to reduce points through the program: 1) Participating in online learning (accumulating at least 30 minutes within 3 days) and passing the exam can reduce 1 point at a time; 2) Participating in on-site learning (each session must be at least 1 hour) and passing the exam can reduce 2 points at a time; 3) Participating in traffic safety public welfare activities (1 hour per session) can reduce 1 point at a time. There are 7 situations in which one cannot apply for the 'Study to Reduce Points' program: 1) Within the current scoring cycle, the driver has two or more full-point records or has accumulated 12 points; 2) In the previous scoring cycle, the driver had two or more full-point records; 3) In the most recent three scoring cycles, the driver was penalized for hit-and-run accidents, drunk driving, using forged or altered vehicle license plates, driving licenses, school bus signs, or other vehicle license plates or driving licenses, or buying/selling points; 4) The driver's license is in the probationary period, overdue for inspection, or has been seized or suspended; 5) The driver has unresolved traffic violation records; 6) The driver has vehicles with overdue safety inspections or vehicles not deregistered as required; 7) The driver engaged in fraudulent activities or impersonation while participating in traffic safety education to reduce points or during full-point education and inspection exams.

Where is the fuse box of the Bora located?

It is located at the top left side of the instrument panel and can be seen after opening the driver's door. The fuses inside the fuse box serve to prevent current overload. In case of an electrical fault in the vehicle, such as excessive current, the fuse will automatically blow to avoid fire hazards. Below are the steps to replace a fuse: 1. Turn off the ignition switch and the corresponding electrical appliance. 2. Insert a flat object (e.g., a screwdriver) into the groove on the outside of the fuse box and carefully pry open the cover. 3. Remove the relevant fuse. 4. If the fuse is blown (metal strip melted), replace it with a new fuse of the same specification (color and markings must match). 5. After replacing the fuse, make sure to reattach the cover properly.

What do E and F mean on the fuel gauge?

E on the fuel gauge stands for empty, indicating low fuel level; F stands for full, representing a full tank. Here are the relevant details: When the needle points closer to the F direction, it means there is more fuel. The closer it gets to E, the less fuel remains. Many vehicle fuel gauges have a red mark near the E position, indicating that the gasoline is about to run out and should be refueled promptly. The fuel gauge is used to display the remaining fuel quantity in the vehicle's fuel tank, which can be either a pointer-type or digital display. It consists of a fuel level indicator with a voltage stabilizer and a fuel level sensor. The low fuel warning system activates when the fuel tank's remaining quantity falls below a specified threshold, alerting the driver with a light to draw attention.
