Why is it easier to shift gears when the car is cold but harder when it's hot?
1 Answers
Cold car easy to shift gears but hot car difficult to shift is caused by the deterioration of clutch pressure plate performance resulting in incomplete separation. Here are specific details about the clutch pressure plate: 1. Structure: The clutch pressure plate has friction linings, similar to brake pads on wheels, made of highly wear-resistant asbestos and copper wires. The friction linings on the pressure plate also have a minimum allowable thickness. After long mileage, the friction linings on the pressure plate need to be replaced. 2. Precautions: Do not half-press the clutch pedal, as this puts the clutch disc in a semi-engaged state. If the clutch pedal is fully depressed, the flywheel and clutch pressure plate are completely separated with no friction between them. If the clutch pedal is fully released, the flywheel and clutch pressure plate are fully engaged, with minimal friction. Therefore, the clutch pedal should not be kept in a half-pressed state.
