What Causes the Clicking Noise When Turning on the Air Conditioning in a Buick Excelle?

Buick Excelle's clicking noise when turning on the air conditioning is caused by an issue with the air conditioning compressor, and it should be inspected and repaired at a 4S shop as soon as possible. Below are some related tips on car air conditioning maintenance: 1. Regularly check the refrigerant and compressor oil: Since modern automotive refrigerants are highly permeable, even a well-functioning refrigeration system may experience reduced cooling efficiency due to refrigerant depletion over time. 2. Clean the condenser surface: The cooling efficiency of the air conditioning system is also affected by the cleanliness of the condenser's cooling fins. Dust, insects, and other debris covering the condenser surface can reduce heat dissipation efficiency. 3. Clean the evaporator surface and replace the air filter: According to the working principle of air conditioning, the surface temperature of the evaporator is very low, making it prone to condensation when exposed to relatively warm outside air.

When parking, should you shift to neutral first or pull the handbrake first?

When parking, whether to shift to neutral first or pull the handbrake first depends on the vehicle type: 1. Manual transmission vehicles: Pull the handbrake first, then shift to neutral; 2. Automatic transmission vehicles: Shift to neutral first, then pull the handbrake. The professional name for the handbrake is the auxiliary brake, which uses a steel wire cable connected to the rear brake shoes to brake the vehicle. Long-term use of the handbrake will cause the steel wire to undergo plastic deformation. Since this deformation is irreversible, long-term use will also increase the handbrake's travel. Neutral usually refers to the state where the vehicle's gear lever is not placed in any forward or reverse gear, and the transmission is completely separated from the drive wheels. The neutral position for manual transmissions is in the middle, while for automatic transmissions, it is marked with an N.

What is the normal temperature for coolant?

Coolant at 90 degrees is normal. Coolant prevents the freezing of the liquid in cold winter conditions, which could otherwise crack the radiator and damage the engine cylinder block. Its full name is antifreeze coolant. Many people think that coolant is only used in winter, but in fact, it should be used all year round. Coolant is a type of cooling liquid with special additives, mainly used in liquid-cooled engine cooling systems. It has excellent properties such as antifreeze in winter, anti-boiling in summer, and anti-scale and anti-corrosion throughout the year. There are many types of automotive coolants, such as calcium chloride from inorganic substances, methanol, ethanol, ethylene glycol, glycerin, lubricating oil from organic substances, and common substances like sugar and honey from daily life, all of which can serve as the base liquid for antifreeze. After adding an appropriate amount of purified soft water, it becomes the general antifreeze coolant.
