What to Do When Car Wiper Blades Shake During Operation?

The simplest and most effective solution is to directly replace the wiper blades with new ones. Check and clean any debris on the wiper blades or underneath them. Inspect the wiper arm or wiper linkage bushing and replace them if necessary. If the wiper motor itself lacks sufficient power and causes shaking, it is recommended to have it checked at a professional repair shop.

Why does the car fail to start when hot but starts immediately when cold?

The reasons why a hot engine fails to start while a cold one starts immediately: Carbon deposits: At high temperatures, carbon deposits have a strong adsorption effect on gasoline. If there are excessive carbon deposits on intake valves, throttle valves, pistons, etc., they tend to absorb some fuel, resulting in an overly lean air-fuel mixture that affects starting. Coolant temperature sensor: The coolant temperature sensor plays a role in adjusting fuel injection pulse width. If it malfunctions and fails to provide correct temperature signals, it will affect engine fuel injection, easily causing abnormal air-fuel ratios in the mixture and hindering startup. Intake air temperature sensor: Similar to the coolant temperature sensor, the intake air temperature sensor also adjusts fuel injection quantity. Higher intake air temperatures lead to richer mixtures, while open circuits or poor grounding of this sensor can cause overly lean mixtures. Both overly rich and lean mixtures can make starting difficult. Fuel quality issues: After a hot engine shutdown, the engine compartment remains at high temperatures. If the fuel itself is prone to evaporation, it can form high vapor pressure in the fuel rail. When this pressure exceeds the fuel system pressure, vapor lock occurs, causing overly lean fuel vapor injection from the injectors and making starting difficult. Fuel injector leakage: Due to the high residual engine temperature after shutdown, leaking fuel turns into vapor entering the intake manifold. Hot starts under these conditions create an overly rich mixture, making starting difficult.

What is the warranty claim process for vehicles during the warranty period?

First, check whether the part listed in the warranty manual matches the actual faulty part. The 4S store will inspect the vehicle, take photos or videos, then match the information and enter it into the system. The 4S store will place an order for the part, which usually arrives in about three days. The repair personnel will then replace it. The owner should keep a copy of the claim form or order form, including photos of the problematic part or issue.

How to Test if a Car Coolant Temperature Sensor is Good or Bad?

Disconnect the coolant temperature sensor connector and set the multimeter to the resistance measurement mode. Connect the red and black probes to the two terminals of the sensor respectively. Disconnect the sensor connector and set the multimeter to the voltage measurement mode. Connect the red probe to the signal wire of the sensor connector and the black probe to the negative terminal of the battery. Unplug the sensor connector and locate the ground wire. Connect the red probe to the positive power terminal and the black probe to the negative power terminal.

Does Not Replacing Spark Plugs Affect Fuel Consumption?

Not replacing spark plugs after a certain usage period can lead to increased fuel consumption, so timely replacement of spark plugs can help save fuel. Replacement cycle for spark plugs: Under normal maintenance conditions, they should be replaced after driving 40,000 to 60,000 kilometers. However, this may vary depending on the brand and engine, so it is recommended to follow the user manual. The following standards can be referenced for maintenance replacement: Platinum spark plugs should be replaced at 40,000 kilometers, ordinary nickel alloy spark plugs at 20,000 kilometers, and iridium spark plugs at 60,000 to 80,000 kilometers. Methods to determine if spark plugs are damaged: Remove the spark plugs and observe their appearance color to assess their condition. Normal spark plugs have insulator skirts and electrodes that appear gray-white, gray-yellow, or light brown. A properly functioning spark plug has an insulator skirt that is reddish-brown, with an electrode gap between 0.8-0.9mm and no signs of electrode burn. If the spark plug has oil stains or deposits but is not damaged, it can continue to be used after cleaning off the oil and deposits. If the spark plug is severely damaged, with signs such as blistering at the top, black streaks, cracks, or melted electrodes, the cause of the damage should be identified. After troubleshooting, replace the spark plug with a new one. Additionally, if the spark plug appears black as if smoked, it indicates the wrong heat range was selected or the mixture is too rich, with oil creeping up.

What are the symptoms of a dirty car throttle?

Engine throttle dirty performance symptoms include: 1. When accelerating, you may feel the throttle sticking, becoming heavy, slow car acceleration, slow RPM rise when pressing the throttle at idle, delayed response, and immediate speed drop when releasing the throttle while driving. 2. A dirty throttle affects the precision and smoothness of engine intake, with the most obvious issue being potential idle shaking or even stalling, as well as unsteady acceleration when pressing the throttle. Content expansion: 1. Mainly due to driving environment, poor air filter filtration, and high dust levels in the surrounding area can cause the throttle to become dirty. 2. Poor quality engine oil with high evaporation rates can lead to throttle contamination. 3. The generation of oil vapor and impurities in the crankcase can cause the throttle to become dirty. 4. After turning off the engine, the throttle cannot be completely sealed, allowing dust to accumulate over time and leading to throttle contamination.
