Can't Remove the Spark Plug?

The reason the spark plug can't be unscrewed is due to using the wrong tool or incorrect force application. Spark Plug Replacement Interval: Under normal maintenance conditions, replace spark plugs after driving 40,000 to 60,000 kilometers. However, this may vary depending on the brand and engine type. It is recommended to follow the user manual. Refer to the following standards for maintenance replacement: Platinum spark plugs should be replaced at 40,000 km, standard nickel alloy spark plugs at 20,000 km, and iridium spark plugs at 60,000-80,000 km. Spark Plug Replacement Steps: Open the hood, lift the engine's plastic cover, and remove the high-voltage ignition wires. Mark each cylinder's position to avoid confusion. Use a spark plug socket to remove the spark plugs one by one. While removing, check for external debris like leaves or dust and ensure they are thoroughly cleaned. Place the new spark plug into the spark plug hole, hand-tighten it a few turns, and then use the socket to tighten it further. Reinstall the high-voltage ignition wires in the firing order, then secure the cover.

How to adjust the time on the dashboard of the Fengon 580?

Here are the steps to adjust the time on the Fengon 580: 1. When the speed displayed on the dashboard is 0, press and hold the 0.0/set button at the bottom right of the dashboard. The odometer and time will appear. 2. Then tap to select and adjust. The setting will be confirmed automatically after a few seconds. 1. The Dongfeng Fengon 580 is an SUV under the Dongfeng brand, offering flexible space with 5-seat and 7-seat configurations to meet diverse travel needs. 2. The Fengon 580 Smart Edition retains its rounded exterior, with a streamlined design that gives the vehicle an elegant look. The internal structure of the taillights has been redesigned for better recognition, and the turn signals feature progressive lighting for a premium feel. 3. The interior adopts a minimalist design, significantly different from the current model, with a more upscale style. The layout of the center console controls is more rational, and the air conditioning buttons are more tactile and clearer. The second-row space is quite comfortable, while the third-row space is adequate, providing a seating posture that avoids noticeable discomfort.

What are the main reasons for high engine fuel consumption?

Engine fuel consumption may be high due to excessive carbon deposits in the engine, damaged oxygen sensors, long overdue replacement of the "three filters," or issues with the engine's electronic control unit. Excessive carbon deposits in the engine: In the short term, excessive carbon buildup in the engine is mainly caused by the use of unsuitable fuel, which is more likely to occur after long-distance driving. Cleaning the carbon deposits can resolve the issue. Damaged oxygen sensor in the vehicle: As an internal control unit of the car, the oxygen sensor primarily monitors the fuel-air ratio in the engine. Once damaged, it can cause an imbalance in the fuel-air ratio, leading to a sudden increase in fuel consumption. In such cases, it is necessary to visit a 4S shop for repair or replacement. Long overdue replacement of the "three filters": During vehicle use, the three filters (oil filter, air filter, and fuel filter) must be replaced regularly. If not changed for a long time, they become dirty and affect performance, sending incorrect information to the engine control unit, resulting in incomplete fuel combustion and increased engine carbon deposits. Replacing the three filters can address this issue. Issues with the engine's electronic control unit: This can directly lead to difficulties in starting the vehicle, increased fuel consumption, poor power performance, and thick black exhaust emissions. Immediate inspection and repair at a 4S shop are required in such cases.

What are the causes of clutch oil leakage?

The causes of clutch oil leakage include leakage from the engine crankshaft rear oil seal, where the leaked oil is engine oil with medium viscosity; leakage from the transmission front oil seal, where the leaked oil is gear oil with high viscosity; and leakage from the clutch slave cylinder, where the leaked oil is brake fluid with low viscosity. During driving, the driver can press or release the clutch pedal as needed to temporarily disconnect or gradually engage the engine and transmission, thereby cutting off or transmitting the power from the engine to the transmission. Repair methods for clutch oil leakage: It is recommended to replace the assembly. Clutch slave cylinder leakage is caused by wear of the piston, sealing rings, and cups inside the slave cylinder, which fail to contain the clutch fluid. However, since clutch slave cylinder parts are not currently available, repairing or replacing sealing rings is not feasible, and the only solution is to replace the entire assembly. The normal service life of a car clutch master cylinder is 60,000 kilometers. The normal service life of a clutch plate, like that of brake pads, is not fixed and depends on factors such as driving habits, road conditions, and load. In other words, faster wear leads to a shorter lifespan, while slower wear results in a longer lifespan. When using a manual transmission clutch master cylinder, it is important to avoid resting your foot on the clutch pedal while driving. When starting, master the engagement point and avoid driving at high speeds in low gears. For automatic transmission vehicles, avoid sudden acceleration during driving.

What are the symptoms of a faulty coolant temperature sensor in the Excelle?

Here are the symptoms of a faulty coolant temperature sensor in the Excelle: 1. The temperature gauge needle does not move or points to the highest position. 2. Difficulty starting the engine when cold, because the faulty coolant temperature sensor still shows a hot engine temperature signal during cold starts, and the ECU cannot receive the signal for a richer air-fuel mixture, only providing the engine with a leaner mixture. 3. Increased fuel consumption, unstable idle; difficulty accelerating, even when the throttle is fully pressed, the engine speed does not increase. Below is additional information: 1. When the coolant temperature sensor fails, it often still displays the hot engine temperature signal during cold starts. The ECU does not receive the signal to provide a richer air-fuel mixture and can only supply the engine with a leaner mixture (the signal for a hot engine), making it difficult to start the engine when cold. 2. Most automotive coolant temperature sensors are made using NTC thermistors. The vehicle's computer receives the resistance value transmitted by the NTC. Therefore, whether the sensor 'fails' due to a short circuit or an open circuit, the vehicle's computer will receive either a resistance of 0 or an infinite resistance. In both cases, the vehicle's computer will determine that the temperature sensor has malfunctioned. The malfunction indicator light will stay on or be accompanied by an alarm sound, and the vehicle will forcibly reduce the intake air volume and fuel injection quantity, lowering the engine's operating speed to avoid unnecessary damage and wear caused by engine overheating.

Where to Find Tire Size Information

Vehicle's original tire size can be found in the owner's manual, on the edge of the left front door, on the storage compartment door or fuel filler cap. You can also locate tire specification information on the sidewall of existing tires. Here's partial introduction about tire specifications: 1. There are multiple representation methods for tire specifications, with four most common types in the market: British, German, metric and American standards. 2. Tire types follow international standard tire codes, expressed in millimeters for section width and aspect ratio percentage, followed by tire type code, rim diameter, load index and speed rating symbol.
