What Are the Reasons Why a Truck Won't Start?

What are the reasons for water entering the car cabin?

Water entering the car cabin can be caused by: 1. Clogged sunroof drainage holes: During rainy days, if the sunroof drainage holes are blocked, rainwater cannot drain out and may seep into the cabin; 2. Aging sunroof rubber seals: Plastic components can harden and deteriorate over time. Once the sunroof rubber seal ages, its sealing performance decreases, leading to leaks during rain; 3. Clogged air conditioning drainage holes: If the condensate water produced by the evaporator cannot drain, it may seep out from the position near the passenger seat; 4. Poor door sealing: Incorrect installation or aging and deformation of the door seals can reduce the car's sealing performance, causing water to enter the cabin during rain; 5. Clogged door drainage holes: Due to their low position, door drainage holes can easily get blocked by mud. If rainwater inside the door cannot drain, it may seep into the cabin.

How Many Kilometers Should an Oil Filter Be Replaced?

It is recommended to replace the oil filter approximately every 5,000 kilometers. The oil filter, generally referring to the oil purifier, is used to remove impurities such as dust, metal particles, carbon deposits, and soot particles from the engine oil to protect the engine. Oil filters are divided into full-flow and bypass types. The full-flow filter is connected in series between the oil pump and the main oil passage, capable of filtering all the lubricating oil entering the main oil passage. The bypass filter is connected in parallel with the main oil passage, filtering only part of the lubricating oil pumped by the oil pump. The functions of engine oil include: 1. Alleviating friction and high temperatures; 2. Reducing gas leakage and preventing external pollutants; 3. Preventing contact between water, air, acidic harmful gases, and engine parts; 4. Buffering the pressure rise at the engine cylinder port; 5. Flushing away dirt generated on the working surfaces of parts.

What to Do When a Car Fogs Up on Rainy Days?

The solutions for car fogging on rainy days are: 1. Wipe it clean with a towel; 2. Turn on the car's heater to clear the fog; 3. Leave a gap in the window to remove fog; 4. Use car glass anti-fog spray. The reason for car fogging on rainy days is: there is a temperature difference between the inside and outside of the car, with the interior temperature being higher than the exterior, causing water molecules in the air inside the car to condense into fog when they encounter the cold. Precautions for driving on rainy days or water-covered roads: 1. Be extra cautious when the water depth exceeds the front bumper; 2. Do not continue driving if the water depth exceeds the engine hood; 3. Avoid driving at high speed through ditches or puddles; 4. Maintain a sufficient safe distance.

Can a vehicle be driven on the road without annual inspection?

Vehicles without annual inspection cannot be driven on the road. Annual inspection can promptly eliminate potential safety hazards, encourage enhanced vehicle maintenance, and reduce the occurrence of traffic accidents. The items for annual inspection include: 1. Check whether the engine, chassis, body, and their auxiliary equipment are clean, complete, and effective, whether the paint surface is uniform and aesthetically pleasing, whether the assemblies have been replaced, and whether they match the initial inspection records; 2. Verify whether the vehicle's braking performance, lights, exhaust, and other safety features comply with relevant regulations; 3. Check whether the vehicle has been modified, remodeled, or altered, and whether the driving license, license plate, and all vehicle registration records match the actual condition of the vehicle; 4. Inspect whether the license plate, driving license, and the enlarged license plate characters printed on the vehicle are damaged, altered, or unclear, and whether they need to be replaced.

Can a Statically Flooded Car with a Dry Engine Still Be Used?

It can still be used. When parked statically, some cars have lower engine air intakes, allowing water to enter the intake tract. In such cases, since the vehicle was not running, simply removing the damp air filter and replacing it is sufficient. Of course, to save money, drying it out is also an option. Related information: 1. Overview: A flooded car refers to a vehicle that has been submerged in water, typically involving the engine and transmission being soaked, with water levels exceeding the wheels and body seats, and prolonged contact between the vehicle's underbody components and water. Such vehicles pose significant risks, as the electrical systems are prone to short circuits and fires. 2. Precautions: "Flooded cars" can be repaired to some extent, but even after repairs, serious hidden dangers remain. The longer the immersion time, the higher the likelihood of malfunctions. This is similar to a watch falling into water—even if it is disassembled and dried, the watch may still malfunction and cannot be completely repaired.
