What Causes Noise During Cold Engine Start-Up?

The reasons for noise during cold engine start-up are: 1. Engine belt slippage; 2. Severe wear of the starter and flywheel; 3. Valve train malfunction; 4. Excessive clearance between hydraulic components and valves inside the engine cylinder head; 5. Timing chain failure; 6. Aging of the drive belt; 7. Three-way catalytic converter malfunction; 8. Engine temperature being too low. Precautions for cold start-up include: 1. Avoid prolonged idling to warm up the engine as components are not fully lubricated and the engine hasn't reached optimal operating temperature; 2. The fuel injector automatically increases fuel injection to raise RPM, normal driving can commence once the engine reaches proper operating temperature.

Does the Emgrand have front and rear anti-collision beams?

Geely Emgrand is equipped with 4mm-thick anti-collision steel beams at both front and rear, providing a high safety coefficient. Below are relevant details about the anti-collision beams: 1. Definition: Both ends of the anti-collision beam are connected to low-speed energy absorption boxes with very low yield strength, which are then bolted to the vehicle's longitudinal beams. These energy absorption boxes can effectively absorb collision energy during low-speed impacts, minimizing damage to the vehicle's longitudinal beams and thus fulfilling their protective role. 2. Structure: The anti-collision beam structure is designed to ensure that the low-speed energy absorption boxes can effectively absorb energy during low-speed impacts through deformation. The anti-collision beam is bolted to the vehicle body for easy disassembly and replacement.

Is a Wheel Alignment Necessary When Changing Tires on a Sedan?

When changing tires on a sedan, a wheel alignment is not necessary; only wheel balancing is required. Situations that do require a wheel alignment for a sedan include: 1. When the vehicle's steering wheel feels heavy, shakes, pulls to one side, is off-center, or does not return to position while driving; 2. Uneven tire pressure and tread wear; 3. Wheel vibration or wobbling; 4. The vehicle pulling to one side. The benefits of a wheel alignment are: 1. Enhanced driving comfort; 2. Increased tire lifespan; 3. Ensuring straight-line stability of the vehicle; 4. Reduced wear on the chassis suspension components; 5. Improved driving safety. The working principle of a wheel alignment is: Based on the four-wheel parameters of the vehicle, adjustments are made to ensure optimal driving performance and a certain level of reliability.

How Many Kilometers to Change Transmission Oil for Automatic Cars?

Automatic cars should have their transmission oil changed approximately every two years or 40,000 kilometers. The steps for changing transmission oil are: 1. Remove the drain plug at the bottom of the transmission to drain the old oil; 2. Remove the inner and outer shells of the transmission; 3. Remove the transmission oil filter; 4. Take off the oil pan gasket and clean the surrounding stains; 5. Use cotton yarn to wipe the cleaned transmission oil filter; 6. Add new oil and complete the installation. The functions of transmission oil are: 1. Keeping the gear system clean; 2. Extending the life of the transmission device; 3. Resisting low temperatures, providing effective lubrication even in cold conditions; 4. Reducing oil loss under harsh operating conditions.
