Currently, the mainstream spark plugs on the market include copper core, nickel alloy core, platinum core, and iridium core. 3. Copper core spark plugs are recommended to be replaced every 20,000-30,000 kilometers; nickel alloy spark plugs have a slightly longer cycle and can be replaced every 40,000-60,000 kilometers. 4. Iridium and platinum core spark plugs have more stable metal properties and better oxidation resistance, so their service life is relatively much longer. Platinum core spark plugs are recommended to be replaced every 80,000 kilometers; iridium core spark plugs are recommended to be replaced every 100,000 kilometers.

Will a Gap in the Windshield Trim Cause Leakage?

A gap in the windshield trim will not cause leakage. Here are specific details about gaps in the windshield trim: 1. Function: In fact, car glass does not rely on the external glass trim for waterproofing; it depends on the sealant inside the glass. The external glass trim only serves a decorative purpose and helps delay the aging of the glass sealant. 2. Repair: After removing the trim, it is essential to clean out any dust, twigs, leaves, or other debris from the trim groove. Otherwise, the adhesive will not hold properly. You can find vehicle-specific trim at auto parts stores or online. During installation, apply a small amount of adhesive to the trim groove and then install the trim. If the trim has not aged, you can directly apply adhesive for reattachment.

What is the difference between the front windshield defroster and the rear windshield defroster?

Here are the differences between the front windshield defroster and the rear windshield defroster: 1. Different methods: The front windshield defroster requires opening the air duct and using blowing air to remove fog, while the rear windshield has embedded heating wires that activate when the switch is turned on, using heat to eliminate fog. 2. Causes of formation: Windshield fogging usually occurs due to a significant temperature difference between the inside and outside of the vehicle. When the outside temperature is lower than the inside temperature, the warm air inside the car condenses on the inner surface of the windshield, forming fog. Conversely, when the inside temperature is lower than the outside temperature, water vapor in the atmosphere condenses on the outer surface of the windshield, forming fog. 3. Different functions: The rear window defroster is designed to address fogging or frost that appears on the rear window during winter or when there is a large temperature difference between the inside and outside of the vehicle, which can severely impair the driver's ability to judge vehicles behind. The principle of this function is that when activated, the embedded heating wires (similar to electric heating elements) on the window heat up, reducing the temperature difference between the inside and outside, causing the fog or frost to reach its melting point, thereby allowing the driver to clearly see the direction of vehicles behind.

What is the wading depth of the Trumpchi GS8?

The wading depth of the Trumpchi GS8 is generally half the height of the tires, and the rim diameter of the GS8 is 19 inches. When the water depth is one-third of the tire height, you can pass through safely without causing unnecessary damage. When the water depth exceeds half the height of the tires, caution is required as this can easily lead to water entering the vehicle. If the wading depth exceeds the bumper, you should be extra vigilant while driving to avoid water entering the engine. Below is an introduction to car wading-related content: 1. Impact: Wading driving may affect the car engine, causing it to stall due to water intake, and may also damage the electronic systems in the car. 2. Damage: If the electronic systems are damaged, it will affect the normal operation of the car. Wading driving can also cause rust on the car's chassis.
