What Causes the Clicking Sound When Driving on Rough Roads?

Car driving on rough roads with a clicking sound is due to loose chassis suspension components. It is necessary to check the tie rod ball joint, lower arm ball joint, stabilizer bar ball joint, rubber bushings, shock absorbers, pressure bearings, and the steering gear. The chassis refers to the combination of the transmission system, running gear, steering system, and braking system in a car. It supports and installs the car engine and its various components and assemblies, forming the overall shape of the car, bearing the engine power, and ensuring normal driving. The transmission system is mainly composed of the clutch, gearbox, universal joint, drive shaft, and drive axle. The running gear consists of the frame, axle, suspension, and wheels. The steering system includes the steering wheel, steering gear, steering knuckle, steering knuckle arm, tie rod, and drag link. The braking system refers to the braking performance of a motor vehicle, which is the efficiency of forcing the vehicle to stop in a short time.

Where is the most suitable location to install ETC?

The ETC installation position for small cars is generally in the upper middle part of the front windshield, while for large vehicles like trucks and buses, it should be installed in the lower middle section. The appropriate installation height should be no less than 1.2 meters and no higher than 2.5 meters, with an installation angle between 30 to 90 degrees. For vehicles with factory-installed or aftermarket explosion-proof film, which may affect microwave communication signal transmission, ETC should be installed in the microwave sunroof strip area. ETC stands for Electronic-Toll-Collection system. To apply for ETC, you need to provide the original and photocopies of the vehicle owner's valid ID card and vehicle registration certificate. If applying by a proxy, the agent's valid ID card is also required. The photocopy of the registration certificate should include the page with the most recent annual inspection stamp. Additionally, a bank card under the owner's name (aged 18-60) is needed for deducting highway tolls. Here are important considerations for ETC installation: 1. Avoid obstructing the driver's view - The best position is behind the rearview mirror: Many car models have steeply angled windshields that already reduce visibility. Installing ETC without considering this may increase blind spots. The right side behind the interior rearview mirror is ideal as it minimizes view obstruction. 2. Ensure proper charging: ETC devices require power but generally don't need manual charging or battery replacement as they feature built-in solar panels. Avoid installing on windshield's blackout areas or positions that might block sunlight to the solar panel. 3. Never remove the device after installation: The adhesive contains an anti-tamper mechanism. The device will lock if removed (triggered by a spring-loaded switch) and requires professional reactivation at ETC service centers. This prevents multiple vehicles sharing one device. ETC usage notes: The effective transaction range is 8 meters. Maintain at least 10 meters distance from preceding vehicles to avoid accidental toll payments for others. ETC lanes have a maximum recognition speed of 20 km/h - excessive speed causes read failures. Insufficient balance in debit card-linked ETC accounts will also lead to payment failures.

How to Bleed Air After Adding Brake Fluid?

Method for bleeding air after adding brake fluid: 1. Lift the vehicle using a jack and secure it properly with jack stands, or drive it onto an inspection pit; 2. Three people are needed: the first person is responsible for loosening the air screws on the four-wheel brake calipers, the second person gets into the driver's seat ready to press the brake pedal, and the third person opens the engine hood, unscrews the filler cap of the brake fluid reservoir, and prepares to add brake fluid into the master cylinder container; 3. Loosen the bleeder screws on the four-wheel brake calipers, place a transparent plastic tube over the bleeder screw of each caliper, and put the other end of the tube into a container filled with brake fluid; 4. Continuously press the brake pedal until all the contaminated brake fluid is discharged; 5. While performing the above actions, continuously add new brake fluid into the container above the master cylinder, but do not let the brake fluid run out, as this would allow air to enter the brake lines, which would prolong the time needed to bleed the air from the lines; 6. After renewing the brake fluid, first tighten the bleeder screws on the four-wheel brake calipers, then proceed with the air bleeding process; 7. When bleeding air, first press the brake pedal 5 or 6 times continuously, then hold it down. At this point, immediately loosen the bleeder screw on the right rear wheel brake caliper and then quickly tighten it. Repeat this action until the brake fluid shoots out of the bleeder screw in a straight line (with strong jetting and no air bubbles).

What grade of gasoline should the new Volkswagen Sagitar use?

Volkswagen Sagitar should use 95-octane gasoline, as recommended in the vehicle's official user manual. In addition to checking the appropriate gasoline grade in the user manual, you can also find it on the fuel tank cap, which will be clearly marked. Generally, the gasoline grade can also be determined based on the engine's compression ratio. Cars with a compression ratio between 8.6-9.9 should use 92-octane gasoline, while those with a compression ratio between 10.0-11.5 should use 95-octane gasoline. If the compression ratio is higher, 98-octane gasoline is recommended. However, with the use of new technologies, the compression ratio alone cannot determine the gasoline grade. High compression ratio engines can also be tuned to use lower-octane gasoline due to other influencing factors such as ignition timing, turbocharging technology, and Atkinson cycle technology. Generally, the higher the gasoline grade, the higher the octane number and the better the anti-knock performance. 92-octane gasoline contains 92% isooctane and 8% n-heptane, while 95-octane gasoline contains 95% isooctane and 5% n-heptane. If the wrong gasoline grade is occasionally used in the Volkswagen Sagitar, simply switch back to the correct grade after consumption. However, long-term use of the wrong gasoline grade can have the following effects: For vehicles that recommend a lower grade, using a higher grade will not cause damage, but the increased octane number can alter the fuel's ignition point, leading to delayed combustion in the engine. This reduces the engine's power output and thermal efficiency, resulting in poorer performance. For vehicles that recommend a higher grade, using a lower grade can cause engine knocking. The significantly lower octane number reduces the fuel's ignition point, causing premature ignition during the compression stroke. If combustion occurs before the spark plug ignites, resistance will develop during the upward stroke. This resistance makes the engine run very unstably. Mild knocking may only increase noise without significant engine damage, but severe knocking indicates serious engine conditions, affecting not only driving stability but also causing abnormal wear on pistons and cylinders, and in extreme cases, cylinder scoring.
