Why does the Roewe 550 still have power to the body after the key is removed?

Can a Tire with a Crack Continue to Be Used?

Whether a tire with a crack can continue to be used depends on the size of the crack: 1. Small cracks that do not significantly affect the tire's structural strength can still be used; 2. Cracks that damage the internal cord layer of the tire cannot be used. Methods for tire maintenance include: 1. Regularly removing stones stuck in the tire tread; 2. Minimizing exposure to direct sunlight; 3. Promptly checking tire pressure; 4. Paying attention to suspension maintenance; 5. Regularly inspecting front wheel alignment; 6. Being mindful of driving habits. The functions of a tire are: 1. Transmitting driving force, braking force, and steering force to facilitate vehicle operation; 2. Supporting vehicle load; 3. Reducing and absorbing vibrations and impacts during driving to prevent severe vibrations from damaging vehicle components.

Is it necessary to replace the tensioner when replacing the alternator belt?

If the belt slips, the tensioner should be replaced along with the belt. Here is detailed information on whether to replace the tensioner when changing the belt: Introduction: A vehicle has two belts: the timing belt and the accessory belt. When replacing them, the tensioner and idler pulley should also be replaced simultaneously. For safety reasons, they should not be used for another 20,000 kilometers before replacement. Precautions: The engine drives various auxiliary mechanisms, such as the air conditioner compressor, power steering pump, and alternator, through belt transmission. If the belt slips or breaks, the related auxiliary mechanisms will fail to operate normally, affecting the vehicle's regular use. Therefore, it is essential to inspect the drive belt regularly.

What Happens When a Car Engine is Low on Oil?

Insufficient engine oil can lead to poor lubrication of the engine's friction surfaces, resulting in abnormal vibrations and reduced power. In severe cases, it may even cause engine bearing seizure. The functions of engine oil are as follows: Lubrication: There is rapid relative sliding between the piston and cylinder, as well as between the crankshaft and bearings. To prevent excessive wear of components, an oil film must be established between these sliding surfaces. A sufficiently thick oil film separates the surfaces of the relatively sliding parts, thereby reducing wear. Auxiliary Cooling: Engine oil has a relatively low specific heat capacity and does not inherently have a cooling effect inside the engine. However, during engine operation, the heat generated by fuel combustion can be carried back to the oil pan by the oil and then dissipated into the air, assisting the radiator in cooling the engine. The actual cooling is performed by the water outside the engine block.

How to Replace the Rear Axle Bushing on a Cruze?

The method for replacing the rear axle bushing on a Cruze is as follows: 1. There are three fixing screws and one center screw. A 17-19 wrench is most important to fix the rear axle. The brake oil pipe is connected to the rear axle, and there is a fixing clip on the oil pipe. Use a hammer to slightly bend it for easier screw removal, but be careful not to break the oil pipe. 2. If it's the first time replacing, flatten the outer iron ring of the bushing towards the center. Carefully observe that a small part of the iron protrudes from the bushing and rear axle. Alternatively, use a sledgehammer with maximum force to strike once. 3. When striking, be careful not to pile up the iron to avoid it getting stuck on the rear axle and making removal difficult. If the iron piles up, use an angle grinder to flatten it, then finally remove the bushing. Repeat the above steps for installation.

At what remaining engine oil level does the warning light activate?

The oil warning light will illuminate when the low-pressure sensor detects oil pressure below 0.3 at idle, or when the high-pressure sensor detects oil pressure below 1.8 at 2000 RPM. The functions of automotive engine oil are as follows: Ensuring smooth component operation: It forms an oil film between two sliding surfaces, preventing friction during operation and ensuring smooth movement of components. Cleaning component surfaces: High-quality oil can flush away contaminants from component surfaces through oil circulation, absorbing tiny metal particles in the engine which are then scraped into the oil pan by the piston oil rings. Cooling and temperature reduction: During engine operation, high temperatures are generated. When oil reaches operating components, it absorbs heat and carries it away, assisting in component cooling.
