What to Do When the Car Hits the Undercarriage After Descending Steps?

1 Answers

The solution to the car hitting the undercarriage after descending steps is to drive the car to a repair shop, lift it up, and carefully inspect the undercarriage. If the pipes are not damaged and only the steel plate has scratches, applying some paint to prevent rust is sufficient. If the pipes are damaged, a thorough inspection and repair are necessary. To prevent severe undercarriage damage from impacts, you can spray undercarriage armor or install an engine guard plate. During the car's design, the undercarriage is built to withstand a certain level of impact. The most vulnerable parts of the undercarriage are various pipes, such as brake hydraulic pipes and fuel pipes. However, these pipes are hidden and protected within the grooves of the undercarriage steel plate and do not protrude beyond the undercarriage's horizontal plane. If the car hits protruding rocks on the ground, the impact surface is point-like, and the protruding rocks may damage the pipes in the grooves, causing oil or fluid leaks, which can be hazardous.

How to Break in a Car After Major Overhaul?

Methods for breaking in a car after major overhaul: 1. Avoid high speeds: The overhauled engine will have speed restrictions, try to maintain a speed below 80 km/h; 2. Avoid emergency braking: Emergency braking not only shocks the braking system during break-in but also increases the impact load on the chassis and engine. Do not perform emergency braking within 300 km after the overhaul; 3. Pay attention to oil maintenance: Use high-quality, high-cleanliness engine oil for the car, and do not use oil below the manufacturer's specified grade. Avoid adding oils with anti-wear additives or various other additives to prevent further engine damage; 4. Coolant check: After the engine overhaul, regularly check the coolant level. Insufficient coolant can cause engine overheating and wear; 5. Warm-up before starting: Warm up the engine before starting. Warming up is actually giving the engine enough time to lubricate, especially for turbocharged models, which must be warmed up before starting, and the lubrication time should be at least one minute.

What Causes the Popping Sound in the Exhaust Pipe of the 10th Generation Accord?

The reasons for the popping sound in the exhaust pipe of the 10th Generation Accord are: 1. Fuel system blockage, poor flow, or abnormal fuel pressure: The electric fuel pump may be malfunctioning or the fuel filter may be clogged, preventing the pressure from reaching the normal range. 2. Restricted air intake or abnormal idle control: Common faults include a dirty stepper motor or throttle valve body, air leaks in the intake system, or abnormal sensors such as those for atmospheric pressure, temperature, and throttle position, leading to incorrect data and control errors. The front grille of the 10th Generation Accord features a large air intake grille with three horizontal decorative bars that stand out, effectively stretching the car's horizontal visual appearance and creating a sense of a wide-body sedan. The dimensions of the car are 4893mm in length, 1862mm in width, and 1449mm in height, with a wheelbase of 2830mm. The 10th Generation Accord offers three powertrain options: 1.5T, 2.0T, and 2.0L hybrid.
