Why does the Besturn B50 trunk leak water?

[LeAnnie]

Car trunk leakage is caused by improper sealing of the weatherstrip or deformation/damage to the trunk. Reasons for car trunk water leakage: Waterproofing in various parts of a car is ensured by weatherstrips made of rubber material. This rubber material inherently possesses certain strength and hardness, making it generally resistant to deformation during use. However, the weatherstrips on cars are consumable items. Prolonged exposure to external air leads to aging, compounded by high frequency of use. Solutions: First, drain the water. There's a rubber drainage plug at the bottom of the spare tire compartment in the trunk - remove it to drain. Locate the leakage point by checking if the trunk lid is deformed or if surrounding rubber seals have aged. Use a hose to spray water and observe where water drips in, or close the trunk to see where light penetrates, then mark these spots. Purchase a bottle of silicone sealant, open the trunk, remove interior panels, and apply sealant to marked leakage areas from the inside, then seal from the outside. The rear bumper must also be removed as sealing isn't possible otherwise. For aged weatherstrips, visit an auto repair shop for replacement.
