Headlight sealant uses silicone sealant. The following are specific requirements for headlight sealant: 1. High-temperature resistance: Headlight sealant is affected by the heat emitted by the bulb. It must maintain its bonding and sealing performance without change in high-temperature environments, while not releasing organic gases, causing fogging, or yellowing, which would affect appearance. 2. UV aging resistance: When exposed to ultraviolet rays from sunlight, the headlight sealant should not experience aging phenomena such as cracking in the adhesive layer. This requires the headlight sealant to have excellent UV aging resistance. 3. Waterproofing: Headlight sealant is also subjected to prolonged erosion by moisture and rainwater, so its sealing performance must not be compromised as a result.

Will a Tire Pressure of 2.8 Cause a Blowout?

A tire pressure of 2.8 will not cause a blowout. The maximum pressure a tire can generally withstand is around 3.5, although this value may vary depending on the brand. Typically, the maximum tire pressure the tire can handle can be found on the sidewall of the tire. The commonly referred to tire pressure is measured when the vehicle is cold. If the tire pressure is 2.8 when the vehicle is hot, it is considered normal. Although a tire pressure of 2.8 will not cause a blowout, it is already on the higher side, and it is advisable to release some air to adjust the tire pressure to the normal range. The specific tire pressure should be based on the manufacturer's recommended value, which can usually be found in the following locations: 1. Vehicle user manual; 2. Label near the driver's door (B-pillar); 3. Drawer next to the driver's seat; 4. Fuel tank cap door.

What Causes Loud Engine Roaring During Acceleration?

Loud engine roaring during acceleration can be attributed to the following reasons: 1. Exhaust pipe leakage: When there is a leak in the intake or exhaust pipe, the exhaust flow rate increases during acceleration. 2. Dirty or clogged throttle valve: During acceleration, the engine load increases, requiring the throttle valve to open wider and more fuel to be injected. If the throttle valve fails to open optimally due to dirt or clogging, it results in poor air-fuel mixture ratio in the engine. 3. Engine misfire: An engine misfire refers to one or more cylinders not functioning properly, leading to insufficient vehicle power and severe exhaust pipe vibrations.

Why Should You Never Change Manual Transmission Fluid?

Manual transmission fluid isn't something you can't change, but rather shouldn't be changed casually. If your car exhibits symptoms like difficult gear shifting, jerky driving, lack of acceleration, or unusual transmission noises, it should be replaced promptly. Generally, manual transmission fluid should be changed every 3 years or approximately 80,000 to 100,000 kilometers. For manual transmissions, the gravity drain method can be used for fluid replacement - this approach is economical, gentle on the transmission, and typically recommended to be performed three times with about 200-kilometer intervals between changes. A manual transmission is a gear-shifting device that alters the speed and torque transmitted from the engine to the drive wheels. It enables the vehicle to obtain different traction forces and speeds under various operating conditions such as starting from standstill, climbing hills, turning corners, and accelerating, while keeping the engine operating within its optimal performance range.
