Is It Normal for Wheel Hubs to Rust?

It is normal for wheel hubs to rust. Wheel hubs should not be replaced casually. Although the structure of tires is simple, when the tire size changes, many parameters of the vehicle will be affected, as the entire vehicle relies on the wheel hubs to make contact with the road surface. Methods for maintaining wheel hubs include: 1. When the vehicle is in a humid area, the wheel hubs should be cleaned frequently to prevent salt from corroding the aluminum surface; 2. If necessary, after cleaning thoroughly, wax can be applied to the wheel hubs for maintenance to keep them shiny. Methods for repairing wheel hubs: 1. Inspect the damage. If the damage does not reach the inner side of the wheel hub, use paint thinner to wipe around the damaged area to remove dirt; 2. The scratched part can be thoroughly cleaned with a toothpick; 3. To prevent accidentally painting unrelated areas, apply adhesive tape around the damaged area; 4. Trim the brush tip, apply touch-up paint, and after the paint dries and contracts, apply a slightly thicker layer; 5. After painting, wait for it to dry completely to complete the repair.

What are the essential items for BMW major maintenance?

BMW major maintenance essential items include: inspecting the engine, chassis, and transmission; replacing the oil filter, cabin air filter, and engine air filter; cleaning the engine and throttle body; checking wheel hubs and brake systems; replacing spark plugs and engine belts; cleaning the air conditioning system; and inspecting the battery - seven key procedures. Major vehicle maintenance, also known as third-level maintenance, is a series of preservation measures implemented after several secondary maintenance cycles to consolidate and maintain the normal operational performance of all assemblies and components. Vehicles should undergo major maintenance every 50,000-60,000 kilometers. This procedure ranks second only to complete vehicle overhaul, focusing on disassembling assemblies for thorough cleaning, inspection, adjustment, and potential issue resolution. Beyond secondary maintenance tasks, it involves deeper cleaning and examination, with necessary disassembly of assemblies or components to eliminate faults, remove carbon deposits, oil sludge, and varnish buildup. This includes flushing oil passages, descaling cooling systems, cleaning oil pans and fuel tanks, disassembling and adjusting chassis assemblies with fluid replacement, inspecting and adjusting wheel alignment, plus conducting frame/body inspections with rust removal and touch-up painting.

Does Leaving the Car Lights On Damage the Battery?

Short-term impact is minimal, but long-term can affect the battery's lifespan. Here are some relevant precautions for car battery maintenance: 1. Turn off all lights before shutting off the engine: Some older models do not support automatic power-off after engine shutdown, so you need to manually turn off the car lights and interior reading lights before shutting off. If you need to find something in the car or require lighting, use a phone or flashlight to avoid forgetting to turn off the lights, which can drain the battery. 2. Avoid leaving the car parked for extended periods: The battery installed in the car will self-discharge over time during prolonged parking. Many car owners find it difficult to start the car or even have a completely dead battery after returning from a business trip or vacation. Therefore, it is best to drive the car at least once a week, preferably for more than 20 minutes, to allow the battery to recharge while driving. 3. Close all windows before shutting off the engine: The car's windows and sunroof switches rely on the battery for power, so it is best to close all windows before shutting off the engine rather than after, or even using the long-press lock button method to close the windows after leaving the car.

What Transmission Does the Buick Regal Use?

Both the Regal 1.5T and 2.0T models are equipped with a 9-speed HYDRA-MATIC automatic manual transmission from General Motors. This transmission is designed for front-wheel-drive transverse platform vehicles and utilizes a one-way clutch, making its size comparable to a 6-speed automatic manual transmission. Below is relevant information about transmissions: Transmission: A transmission is a device that changes speed ratios and the direction of motion. It is used in automobiles, tractors, ships, machine tools, and various machines to alter the torque, speed, and direction of motion transmitted from the driving shaft to the driven shaft under different working conditions. Gear-driven transmissions generally consist of a casing and several gear pairs. Transmissions are divided into manual and automatic types. Manual transmissions primarily consist of gears and shafts, achieving speed and torque changes through different gear combinations. Automatic transmissions (AT) are composed of a torque converter, planetary gears, a hydraulic torque control system, and a hydraulic control system. Speed and torque changes are achieved through hydraulic transmission and gear combinations. Transmission Maintenance: Regularly replace the transmission fluid. For manual transmission vehicles, replace the transmission fluid every 3 years or 60,000 kilometers. For automatic transmission vehicles, replace the transmission fluid every 4 years or 60,000 to 80,000 kilometers.

What Causes a Car's Electric Fan to Keep Running?

Car electric fan keeps running due to reasons such as coolant temperature not reaching the required level, relay malfunction, or issues with the temperature control switch. Related explanations are as follows: Long-term lack of lubrication: Electric fan control method: Unlike engine-driven fans, car electric fans need to adjust their operation based on the coolant temperature. Some are controlled by the vehicle's ECU, while others operate via a thermistor switch. Different cars have varying electric fan control methods. Structure: Generally, the electric fan assembly includes the fan itself, bracket, temperature sensor, temperature control switch, relay, wiring harness, etc. If the car's electric fan fails to operate, troubleshooting can be conducted based on the above factors. Components: The engine consists of five major systems: cooling, lubrication, ignition, fuel supply, and starting system. Main components include the cylinder block, cylinder head, piston, piston pin, connecting rod, crankshaft, flywheel, etc. The working chamber of a reciprocating piston internal combustion engine is called the cylinder, with its inner surface being cylindrical. The piston moving reciprocally inside the cylinder is connected to one end of the connecting rod via the piston pin, while the other end of the connecting rod is linked to the crankshaft. The crankshaft is supported by bearings on the cylinder block and can rotate within them, forming the crank-connecting rod mechanism.
