If there is water accumulation in the car's fuel tank, the vehicle may frequently stall. The presence of water can lead to rust, corrosion, and aging of the fuel tank. If there is water in the fuel system, it can result in reduced engine power, increased fuel consumption, vehicle shaking, and difficulties starting the engine, especially in winter. Symptoms of water in the fuel tank include hard starting, engine backfiring, high idle speed, or insufficient power. The correct way to drive through water: 1. Slow down or stop to observe: When encountering water on the road, if the water level exceeds the bumper or two-thirds of the tire height, driving through it poses a certain risk. Additionally, driving too fast through water can cause splashes to enter the engine compartment or the interior through the chassis. Assess the water level; if it is high, try to detour and avoid forcing your way through. 2. Do not stop or shift gears: When driving through water, maintain a steady speed in a low gear with moderate throttle, drive at a low speed, and avoid stopping, shifting gears, or releasing the throttle. 3. Do not restart the engine: If the car stalls in water, take measures to tow it to a safe location with less water as soon as possible. Do not attempt to restart the engine to avoid damaging it. 4. Remove brake pad moisture promptly: To prevent the vehicle from losing braking power after driving through water, which could lead to danger or accidents.

Will the car rust if the primer is exposed?

If the car's primer is exposed, it will rust. It is recommended to address the rust promptly. Methods to deal with rust are as follows: Replacement of parts: If the collision or scraping damages the chrome-plated parts, and there is visible damage, it is advisable to replace the parts to maintain the vehicle's appearance (aesthetics). Although such materials can be re-plated through electroplating, the cost for a single part is relatively high, making direct replacement more suitable. Polishing treatment: For minor scrapes that do not damage the primer, or even just small surface abrasions or marks left by scraping, polishing can be used as a treatment method. This can largely restore the original appearance.
