What Causes the Engine Fan to Keep Running Continuously?

1 Answers

When the car's water temperature is normal but the fan keeps running, it is mostly due to a damaged thermostat or the absence of this sensor's function. The sensor detects the engine's water temperature, and when the temperature rises, it activates the fan. If it fails, the fan remains operational regardless of the water temperature. Maintenance methods are as follows: Under normal circumstances: When the water temperature reaches the predetermined level, the thermostat opens, allowing the radiator water to circulate. When the engine temperature reaches a certain level, the radiator's electric fan will start running through sensor detection. In colder temperatures: The fan rarely activates while driving. If you suspect an issue, you can test it by revving the engine to under 2500 RPM while stationary. Normally, the fan should start within about 10 minutes. Generally, if the vehicle has a thermostat installed and the water temperature is not too high or not boiling, there should be no major issues. It's best to visit a service station to measure the water temperature with diagnostic tools. When using antifreeze: To prevent radiator corrosion, always use long-lasting rust-proof and antifreeze solutions produced by reputable manufacturers that comply with national standards. During radiator installation: Avoid damaging the cooling fins or denting the radiator to ensure proper cooling capacity and sealing. In daily use, regularly check the water level and only add water after the engine has cooled down: When adding water, slowly open the radiator cap, and keep your body as far away as possible from the filler neck to prevent burns from high-pressure steam. Depending on actual conditions, users should perform a complete core cleaning of the radiator every 1 to 3 months: During cleaning, rinse the core with water against the airflow direction. Regular thorough cleaning prevents clogging of the radiator core by debris, which could impair cooling performance and reduce the radiator's lifespan.

What are the standard dimensions for a reverse parking garage?

The standard dimensions for a reverse parking garage are as follows: For small cars, the garage length is 5.25 meters and the width is 2.3 meters. For large vehicles, the dimensions are 16 meters in length and 6.83 meters in width. The evaluation criteria for reverse parking: Failure to follow the prescribed route or sequence results in disqualification; vehicle body crossing the line results in disqualification; failure to fully enter the garage results in disqualification; stopping midway results in disqualification; exceeding 4 minutes results in disqualification. Reverse parking rhyme: Reversing in and out isn't hard, fasten seatbelt, shift gear, left signal flash. Press clutch, release handbrake, slowly lift clutch to start gently. Watch right line to adjust car body, left mirror seam follows right line. Stop when front line aligns with shoulder, engage reverse gear, release clutch. When left mirror covers corner line, turn steering wheel fully right. Watch left mirror for garage line, at 30-degree angle turn back one round, when car parallels line, straighten wheel two full turns. When left mirror covers front garage corner, press clutch and brake. Engage first gear to exit, turn left fully when hood touches line. Stop when hood covers line, keep steering position to reverse. Watch right mirror for garage line, at 30-degree angle turn back one round, when car parallels line, straighten wheel two full turns, when left mirror covers front garage corner, press clutch and brake. Engage first gear to exit, turn right fully when hood touches line. Stop when hood covers line, adjust car body skillfully. The new garages have no poles to reference, only ground markings. The garage length is much shorter than current standards - just enough to fit one car completely. The process involves reversing in from the right, driving out and turning left, then reversing back in, finally driving out to return to start point. This simplified process eliminates the current test's garage shifting step.

What Does Tbox Failure Mean?

Tbox failure means there is a problem with the vehicle's telematics system's onboard Tbox. In this case, it is necessary to visit a 4S shop to check the fault code and then determine the fault information. Most issues typically occur with the radar probe, resulting in the inability to retrieve vehicle information. If all fault lights remain on, it may indicate that the vehicle's own module upgrade has failed or that a malfunction has occurred during use. It is advisable to visit a service station to attempt a firmware update or replace the Tbox module to resolve the related issue. The Tbox is a telematics system specifically designed for automobiles. Its working principle involves using an app on a smartphone to send commands to the Tbox system via background monitoring. Upon receiving the commands, the vehicle is controlled via the CAN bus, allowing operations to be viewed and executed on the phone, such as turning on the air conditioning or adjusting the seat position in the office. The Tbox system can collect and record the vehicle's driving data, store it in the system, and analyze this data before displaying it on the screen. Using the Tbox system, users can remotely query and control the vehicle, including actions like unlocking doors, honking the horn, flashing lights, turning on the air conditioning, and starting the engine.

What issues should be paid attention to when learning to drive?

Matters needing attention for the driving test: 1. Choosing a driving school is very important for the driving test, be careful not to be deceived. 2. Choosing a coach is even more important, it's best to contact a coach with whom you have a good relationship in advance. 3. A physical examination is required before learning to drive, but as long as you are healthy, have normal vision and are not color blind, you can pass. 4. The first subject, the theoretical test, is relatively simple. Read the tutorial book 1-2 times, and then do the questions in the question bank 1-2 times, and there will be basically no problem. 5. Subject two is the field test, which takes the longest time to learn, including five items: reversing into the garage, parallel parking, right-angle turning, S-curve, and stopping and starting on a slope. It seems simple, but it is easy to make mistakes, so more practice is needed. 6. Subject three is the road test, which has more items, but the learning time is very short, only 1-3 days. The items include preparation before getting on the car, starting, driving straight, changing lanes, passing intersections, pulling over, passing pedestrian crossings, passing school areas, passing bus stops, meeting cars, overtaking, turning around, driving at night, shifting gears, turning left at intersections, and turning right at intersections—16 road driving skills in total. It seems like a lot, but these are all things you need to use when driving on the road normally. 7. Currently, there is one more subject for the driving test, subject four, which is similar to subject one and is also a theoretical test. The difference is that the theoretical test of subject four pays more attention to some practical operations.

What is the standard tire pressure for the Ford Edge?

The normal tire pressure range for the Edge is 2.4-2.5 bar. Due to seasonal factors, the tire pressure can be appropriately increased by 0.2 bar in winter and reduced by 0.1 bar in summer. When one or more tires are detected to be significantly underinflated, a warning light will illuminate. If the low tire pressure warning light comes on, you should stop and check the tires as soon as it is safe to do so, and inflate them to the correct tire pressure. If the tire pressure monitoring indicator light comes on (a yellow symbol, an irregular circle with no seal on top and four small spikes at the bottom, with an exclamation mark inside), there are generally three possible causes: Abnormal tire pressure: The system usually alerts when the pressure is below 1.8 bar or above 3.0 bar. In this case, the tires need to be checked and the pressure adjusted. Tire pressure monitoring not reset: After inflating the tires, the tire pressure monitoring system was not reset in time, causing it to still record the previous data, which triggers the tire pressure monitoring indicator light. Simply performing a tire pressure reset will resolve this issue. Damaged tire pressure sensor: The tire pressure sensor, which is used to monitor tire pressure, is directly installed inside the tire and connected to the tire inflation valve. If the sensor is damaged during driving (e.g., by hitting a curb), it can also cause the tire pressure warning light to illuminate. For sensor damage, the only solution is to replace it with a new part.
