What Lubricant to Use for Window Seals?

Window seals can be lubricated with high-quality window lubricants. Here is some relevant information about car windows: 1. Types: Car windows are generally categorized into four types: front and rear windshields, ventilation windows, heat-insulating side windows, and sunroofs. The front and rear windows of a car usually employ curved glass that enhances visibility while maintaining aesthetic appeal, secured with rubber sealing strips embedded in the window frames or specialized adhesives. To facilitate natural ventilation, side windows are typically designed to move up and down or forward and backward. 2. Window Materials: As early as 80 years ago, glass was already installed on Ford's Model T, where flat glass was mounted at the front of the cabin to protect drivers from wind and rain. In the decades that followed, the glass industry gradually became involved in the automotive sector, developing various types of safety glass—laminated glass, tempered glass, and zone-tempered glass—significantly improving the performance of automotive glass.

What Causes Engine Hesitation Between 1500 to 2000 RPM?

Carbon deposits and oil sludge blockage: After prolonged use, carbon deposits and oil sludge can accumulate in the throttle body, idle valve, and intake ports, leading to restricted airflow. This can affect idle stability and cause shaking. Below are some explanations regarding engine hesitation: 1. Special circumstances: Check if the ignition system has been exposed to water. Sensors or water entering the intake system can wet the air filter, affecting the air intake volume and introducing small amounts of water. 2. Causes: Transmission oil passages may be obstructed or not flowing smoothly. Wear in the valve body, prolonged lack of transmission fluid changes leading to degradation and reduced lubrication, a dirty transmission filter with poor filtration can allow wear particles to enter the valve body.
