Where is the front drainage channel located?
1 Answers
Automotive front drainage channels are located at the front end of the windshield and on the upper parts of the left and right fenders, i.e., on both sides of the engine hood. Below are specific details about the front drainage channels: 1. Function of the vehicle body drainage channels: The drainage channels on the vehicle body are designed to direct rainwater along the channels to the outside of the vehicle, preventing water from entering the interior of the car body and the internal sheet metal structure. This ensures a comfortable interior space and prevents premature rusting of the sheet metal due to rainwater. 2. Structure of the drainage channels: The rear pillar drainage channels are typically formed by welding the upper section of the rear drainage channel and the rear combination lamp mounting plate. The top is welded to the roof panel, the sides to the outer side panels, and the lower part to the rear panel. They have a specific cross-sectional shape, forming a water channel that runs from the roof panel along the rear pillar to the bottom of the vehicle body. Structurally, they are required to direct water from the roof downward and out of the vehicle body, ensuring that rainwater does not enter the interior through the roof, wiring holes, or tail lamp mounting holes.
