Applying some water can temporarily alleviate the squeaking of the car belt. The reason is that the noise is caused by slipping, which may be due to powder on the contact surface. Watering can clean the powder, improving the slipping condition, but the looseness is not fundamentally resolved, and the noise will reappear after some time. Solutions to belt squeaking issues: 1. Apply polyol solution to the belt: Polyol solution can effectively prevent the belt from hardening and maintain its elasticity, thereby addressing the issue of insufficient friction. 2. Adjust the tensioner pulley: The tensioner pulley is responsible for keeping the gear and belt in close contact. Tightening the tensioner pulley can effectively increase the belt's friction, eliminating various squeaking noises. 3. Replace the belt: When the belt shows signs of aging, it should be replaced promptly. An aged belt can cause slipping, affecting the vehicle's normal operation.

What is the fuel tank capacity of the Changan Eado V7?

The fuel tank capacity of the Eado V7-2016 1.6L Manual Leshang Model (China V) is 45L. It is equipped with a 1.6L naturally aspirated engine and a 5-speed manual transmission (MT). The drivetrain is front-engine, front-wheel drive. The front suspension type is MacPherson independent suspension, and the rear suspension type is torsion beam non-independent suspension. Among vehicles in the same class, the Beijing U5-2020 1.5L Manual Luxury Model (China VI) has a fuel tank capacity of 48L. During actual refueling, the amount of fuel may exceed the calibrated capacity. This is because the fuel tank capacity specified by the manufacturer is measured from the bottom of the tank to the safety level. There is additional space from the safety level to the tank opening, which is designed to allow for fuel expansion due to temperature increases without causing overflow. If fuel is filled up to the tank opening during refueling, the actual refueling amount may exceed the calibrated tank capacity. To check the remaining fuel level, the owner can observe the fuel gauge on the right side of the instrument panel, which is marked with E and F. When the pointer is near E, it indicates low fuel, and when it is close to F, it means the fuel level is sufficient.
