Whether water in the engine requires an overhaul generally falls into three scenarios: Here are the relevant explanations: 1. Engine submerged in water: If you promptly call for a tow truck to take it to a repair shop and it is cleaned properly, there should be no issues, and an overhaul is not necessary. 2. Slight water ingress in the engine: This is the most dangerous scenario because the vehicle can still start normally, and many people continue to drive without realizing the problem, leading to an engine overhaul or complete failure. 3. Engine cylinders filled with a large amount of water: The crankshaft cannot rotate, and the starter does not work. Even if the ignition switch is turned on, the vehicle cannot start. In this case, there is also a risk of requiring an overhaul.

Last time I was driving in a heavy rainstorm, my car went into a big puddle, the engine made a creaking sound and then stalled. I quickly pulled over, opened the hood, and saw that the water was almost up to the cylinder block. After towing it to the repair shop, the technician found that the connecting rod was bent and several pistons were burned out, resulting in a major overhaul. Remember everyone, water entering the cylinders can cause hydraulic lock, and once the engine runs, it may be ruined. This is not something to take lightly, as delaying the repair can also affect the safety of other components. My advice is not to start the car immediately after water intrusion, and it's best to tow it to a professional shop for diagnosis. In severe cases, a major overhaul is unavoidable. Always avoid deep water when driving, especially during heavy rainstorms. Proper maintenance can prevent problems before they occur.

What is the car hold function?

Car hold refers to the auto hold function. Auto hold is an automatic braking feature. After activating this function, for example when stopping at a traffic light, it eliminates the need to pull the handbrake, simplifying operations by avoiding the use of manual or electronic handbrakes. For automatic transmission models, it also prevents frequent shifting between D to N or D to P. If a car is equipped with an auto hold system, the handbrake will automatically engage once the car comes to a complete stop. In this situation, the driver doesn't need to shift to N gear or keep pressing the brake pedal to maintain the car's stationary position. To resume driving, simply press the accelerator pedal.

What to Do If You Forget to Release the Handbrake While Driving?

If you forget to release the handbrake while driving and only drive a short distance before noticing, the impact on the vehicle is minimal and can be ignored. However, if you drive a long distance with the handbrake engaged, it is likely to cause damage to the handbrake. In such cases, you must promptly visit a 4S shop or a professional auto repair shop to have the handbrake repaired. When the handbrake is engaged, the dashboard will display a warning symbol—usually a circle with the letter "P" inside or a circle with an exclamation mark. These symbols indicate that the handbrake is in the engaged state. The handbrake, also known as the parking brake, functions by providing resistance to the vehicle when parked, preventing it from rolling away.

What causes blue smoke when starting a cold car?

The reasons for blue smoke when starting a cold car: 1. Aging, damage, or failure of the valve stem seals, excessive clearance between the valve and guide; 2. Blockage or damage of the Positive Crankcase Ventilation (PCV) valve, leading to trapped exhaust gases in the engine, increased crankcase pressure, causing some engine oil to enter the combustion chamber and participate in burning; 3. Internal engine wear, such as excessive wear between the piston and cylinder wall due to prolonged use or improper maintenance, allowing oil to enter the cylinder and participate in combustion; 4. Piston ring misalignment, excessive end or side clearance, stuck piston rings, or severe piston ring wear; 5. Air filter issues or blockage in the intake system causing poor airflow, overly rich air-fuel mixture, leading to excessive oil being drawn into the combustion chamber and participating in combustion.

How to jump-start a car with a dead battery?

To jump-start a car with a dead battery, follow these steps: 1. First, prepare a set of jumper cables. Then, open the hoods of both vehicles to locate the battery terminals. 2. The positive terminal is marked with a plus sign (+), and the negative terminal is marked with a minus sign (-). Connect the positive terminals of both batteries with the jumper cable, and then connect the negative terminals in the same manner. Once the connections are secure, you can attempt to start the vehicle. The typical lifespan of a car battery is 3 to 5 years, depending on usage. Frequent use of air conditioning, music, videos, or forgetting to turn off headlights without the engine running can drain the battery quickly. If your car battery dies, you can also call your insurance company or a 4S dealership, as many offer free jump-start services or towing.

Can You Use Wipers After Applying Window Film?

You can use wipers after applying window film. The wipers are located on the exterior of the car's front windshield, while the applied window film is on the interior of the front windshield, so there is no contact between the two. Car window film involves applying a thin layer of material to the front and rear windshields, side windows, and sunroof. This layer is also known as solar film or explosion-proof heat-insulating film. The primary functions of car window film are to block ultraviolet rays, reduce heat, and prevent injuries caused by sudden glass breakage. Additionally, due to the one-way visibility feature of solar film, it helps protect personal privacy. It also minimizes damage to items and passengers inside the car from UV exposure and, to some extent, contributes to reducing fuel consumption.
