To identify the source of the resonance, if it's caused by the engine mounts, it would result in vibration rather than resonance, which can be felt by touching the steering wheel. Here is some relevant information about the Buick Excelle: 1. Exterior Design: The new Excelle primarily features improvements in details. The front grille's decorative strips have a stronger three-dimensional effect, and the lower air intake adopts an integrated design. Additionally, the structure inside the headlight assembly has been slightly adjusted. Compared to the older model, the new Excelle focuses on the upgraded powertrain, with improvements in fuel economy expected to enhance its competitiveness in the market. It is anticipated to remain a solid choice for a family sedan after its release. 2. Fuel Consumption: The new Excelle 1.5L DVVT manual transmission model has a combined fuel consumption of 6.6L/100km, while the automatic transmission version consumes 7.6L/100km. This represents a reduction of 1.1L and 0.4L respectively compared to the older 1.6L manual and automatic models. According to the latest official information, the upcoming new Excelle will be equipped with a 1.5L DVVT engine, replacing the older 1.6L engine. The transmission system has also been upgraded, with the 1.5L DVVT engine paired with either a 5-speed manual or a 6-speed automatic transmission, while the older 4AT transmission will no longer be used.

How to Remove the Steering Wheel of Changan CS35?

Disassembly tools include a flat-head screwdriver and a hexagon socket tool. Since fingers are more flexible and can better control the force, there's no need to remove the airbag. The area to be disassembled is the region circled by the black line in the diagram. The components in this area must be removed as a whole, meaning the fake switch and the 7-shaped brown decorative strip below should be taken off together.

How to Deal with Rear Wheel Lock-up on Changan CS35?

First, drive forward and backward three times, but avoid excessive movement to prevent forced dragging and wear on the tires. Pour boiling water (100°C) between the brake pads and the brake drum. The thermal expansion may cause them to separate automatically, after which you can try the above method again. Gently tap both sides to potentially separate them. If that doesn't work, try kicking the tire a few times to loosen it. If all else fails, consider removing and reinstalling the brake pads.

How to operate the defogging function on Changan CS75?

First press the A/C switch button, then activate the front windshield defogging button, set the temperature to the lowest level, and adjust the airflow to eliminate fogging. When the car is just started, do not turn on the air conditioner immediately. After the water temperature rises, begin heating, set the airflow to maximum, and turn on the defogging button to make the fog disappear.

What Happens If the Engine Lacks Antifreeze?

Lack of antifreeze in the engine can cause the engine temperature to rise excessively, which can easily lead to engine damage. The full name of antifreeze should be antifreeze coolant, meaning it is a coolant with antifreeze properties. Antifreeze prevents the coolant from freezing and expanding in cold winter conditions, which could otherwise crack the radiator or damage the engine cylinder block or head. Antifreeze is a type of coolant containing special additives, primarily used in liquid-cooled engine cooling systems. It offers excellent performance in preventing freezing in winter, boiling in summer, and protecting against scale and corrosion year-round. An engine is a machine that converts other forms of energy into mechanical energy, including internal combustion engines, external combustion engines, jet engines, electric motors, etc.

Should You Keep the Old Tires After Replacing Car Tires?

You can take the old tires with you after replacing car tires. If the replaced old tires are not severely worn, they can still be used as full-size spare tires. Uses of old tires: Tire Retreading: Tire retreading technology involves refurbishing and processing tires that have been worn or damaged due to other reasons, restoring them to usable condition. Oil Extraction from Waste Tires: The technology for extracting oil from waste tires involves heating, pressurizing, and adding catalysts to refine fuel from discarded tires. If simple and inexpensive equipment is used for this technology, it can easily cause secondary pollution. There are many hidden illegal workshops in remote mountains in China that engage in this practice, and there have been numerous reports about them in recent years. Rubber Powder from Tires for Waterproofing and Leak Repair: Waterproof membranes are mainly used for building leak repairs. Nowadays, most buildings undergo waterproofing and leak prevention work, and this industry is widespread across the country. The demand for waterproof membranes is enormous, and rubber powder is also a primary raw material for this technology, as waterproof membranes are a type of modified asphalt.
