How Often Should Engine Wiring Harness Protection Be Maintained?

Engine wiring harness protection should be maintained once a year after 3 years of use. Hazards of Engine Wiring Harness Failure: Long-term exposure to high temperatures in the engine compartment can cause the wiring harness surface to crack and peel, exposing wires and leading to electrical leakage. The wiring harness connectors may oxidize and corrode due to moisture and impurities in the engine compartment, or become loose from vibrations, resulting in poor contact. The most severe consequence of wiring harness aging is vehicle self-ignition. Engine Wiring Harness Maintenance: Regular wiring harness maintenance is essential. Wiring harness maintenance typically involves using a wiring harness protector. Its working principle is to form a protective film on the engine wires/battery terminals and harness surface, isolating moisture and preventing oxidation. Since the spray itself has high-voltage resistance and insulation properties, it can also delay the aging and cracking of rubber and plastic pipes in the engine compartment, preventing electrical leakage caused by harness aging. Additionally, the applied protective film is less prone to dust accumulation, making it easy to wipe and maintain engine compartment cleanliness for extended periods.

Is there a difference between electronic shift levers and conventional shift levers?

There is a difference between electronic shift levers and conventional shift levers, and the differences are as follows: 1. Different uses: Electronic shift levers are generally for automatic transmissions; conventional shift levers are divided into manual and automatic transmissions. 2. Different principles: Electronic shift levers achieve gear shifting through electric motors; conventional shift levers directly control the manual valves of the transmission via linkages. The usage method of an electronic shift lever is as follows: 1. When parking, press the 'P' button on top of the shift lever to illuminate the 'P' letter, engaging the parking gear. 2. Pull the shift lever backward once to light up the 'D' indicator, engaging the 'D' gear, after which the electronic shift lever automatically returns. 3. When the transmission is in 'D' gear, pulling the shift lever backward once lights up the 'M' indicator, engaging manual mode. 4. When in 'D' or 'R' gear, pushing the shift lever in the opposite direction of the current gear lights up the 'N' indicator, engaging neutral gear. 5. Holding down the unlock button on the left side of the shift lever and pushing the lever forward lights up the 'R' indicator, engaging reverse gear.

How to Replace a Car Tire?

Steps to replace a car tire: 1. Park the car on a flat surface or any other convenient location that does not obstruct others, ensuring there is no risk of the car rolling forward or backward; 2.

Place the jack in a secure position and lift the side of the car where the wheel is to be removed, ensuring sufficient clearance between the wheel and the ground; 5. Unscrew the nuts; 6. Pull the wheel until it is completely removed. If the nuts are stuck, tap them gently with a hammer, but be careful not to overdo it, as this may damage the brake pads.

How to Deal with the Tayron's Windshield Wipers Not Standing Up?

Tayron windshield wipers not standing up reasons introduction: Temperature too high or too low: In hot summers or cold winters, it is necessary to lift the vehicle's windshield wipers. Because in the scorching summer, if the car happens to be parked in an open-air parking lot under direct sunlight, the surface temperature of the front windshield can reach over 50 degrees Celsius. At this time, the wipers are tightly pressed against the window glass, and prolonged exposure to the sun can easily cause the rubber of the wipers to deform due to heat, preventing them from functioning properly to clear rainwater. In the winter of northern regions, temperatures often drop below freezing. If the wipers are not lifted, they will freeze together with the glass, making them difficult to separate and causing the rubber strips to deform, which can also render the wipers useless. Dust and dirt: When parking outdoors for extended periods, avoid excessive accumulation of dust, fallen leaves, bird droppings, etc., so that when used again, they won't mix with the windshield washer fluid and smear the windows, obstructing visibility.
