Which Parts of a Car Should Avoid Water Exposure?

There are three main areas in a car that should avoid water exposure: the engine compartment, the exhaust pipe, and electrical circuit interfaces. Below is a detailed explanation: 1. Engine compartment: If water enters this area, it can dilute the gasoline in the engine, leading to insufficient lubrication upon startup, which causes wear and tear. In severe cases, it can seize the cylinders, similar to a syringe becoming stuck—unable to compress or release water. Attempting to start the car in this condition can deform the cylinders, necessitating replacement at a repair shop. 2. Exhaust pipe: Water accumulation in the exhaust pipe can corrode delicate components such as the catalytic converter and oxygen sensor. Car exhaust contains chemicals that, when mixed with water, form a highly corrosive liquid. If this liquid damages these sensitive parts, the car may no longer function properly. 3. Electrical circuit interfaces: Modern cars have many exposed interfaces like USB ports and cigarette lighters. If water enters these during washing, it can cause short circuits and potentially damage the car's electrical system.

What is the main purpose of engine running-in after overhaul?

The purpose of engine running-in after major overhaul is to ensure a tight seal between piston rings and cylinder walls. To guarantee running-in effectiveness and protect engine performance, the engine running-in process must be strictly operated and completed according to relevant procedures. Engine running-in refers to the trial operation that adopts specific motion condition parameters and working specifications according to engine characteristics, aiming to make the surface conditions and mechanical-physical properties of new or overhauled engine assemblies reach a state suitable for long-term operation. Engine running-in generally consists of three stages: cold running-in, hot running-in, and dynamometer testing. Cold running-in uses external power as the power source to operate main engine components under sufficient lubrication conditions with regulated speed variation and increasing loads. Hot running-in uses the properly functioning engine itself as the power source, systematically varying speed and increasing loads under normal working conditions until reaching rated power and speed. Dynamometer testing measures fuel consumption and power output at rated speed conditions to evaluate the quality of engine assembly, manufacturing, or repair.

Do I Need to Replace the Wheel Hub When Changing Tires?

You do not need to replace the wheel hub when changing tires. As long as the wheel hub is not damaged, you only need to replace the tire with the same size and specifications as the original factory tires. The functions of tires are: 1. To transmit driving force, braking force, and steering force to achieve vehicle operation; 2. To support the vehicle load; 3. To reduce and absorb vibrations and impacts during driving, avoiding severe vibrations that could damage vehicle components. Tire maintenance methods include: 1. Regularly cleaning stones from the tire treads; 2. Minimizing exposure to direct sunlight; 3. Promptly checking tire pressure; 4. Paying attention to suspension maintenance; 5. Regularly inspecting front wheel alignment; 6. Adopting careful driving habits, choosing smooth road surfaces, avoiding objects that could puncture or scratch tires, and steering clear of chemical spills that could corrode tires.

Does Rain Affect a Car After Waxing?

Rain does not affect a car after waxing. Waxing is a common maintenance procedure for the car's paint surface, serving to waterproof, protect against acid rain, and also shield against high temperatures and UV rays. Benefits of waxing: When a car is exposed to sunlight for extended periods, the paint can age and fade. The thin film formed by wax reflects some of the light, thereby protecting the paint. UV-resistant car wax is specifically designed to mitigate the harmful effects of UV rays on the car's surface. During use, cars inevitably endure wind, rain, and sand, which can cause some damage to the paint. Moreover, if a car is not washed regularly, the paint is more susceptible to corrosion. Drawbacks of waxing: Wax contains abrasive particles, and the shine on the paint is actually achieved by microscopic particles that are invisible to the naked eye. If the wax is applied in a circular motion, frequent waxing can lead to fine circular scratches on the paint surface. To some extent, long-term waxing can subtly wear down the paint over time.
