How to Deal with Drainage Channels on Both Sides of the Trunk?
2 Answers
Engine drainage holes are usually located at the rear of the engine compartment and can be seen below the front windshield. Sunroof drainage holes are hidden around the edges of the sunroof, connected to the car's A-pillar and C-pillar via conduits, allowing rainwater to flow out along the pillars during rain. The fuel tank cap drainage hole is inside the fuel tank cap and can be seen upon opening it. If any liquid drips into the fuel tank cap groove during refueling, it can be drained out through this hole.
My trunk drainage channels often get clogged, and I always handle the cleaning myself—it's convenient and saves money. First, locate the drainage holes on both sides of the trunk, usually positioned in the corners. Use a small vacuum or compressed air to blow out accumulated dust, leaves, and other debris. Then, pour some water to test the flow—if it's blocked, gently unclog it with thin wire or an old toothbrush. For severe blockages, you might need to remove some trim panels for deeper cleaning. This prevents rainwater from backing up into the trunk, which could cause waterlogging, damage to the spare tire or wiring, and increase the risk of rust. After making this a habit, my car stays cleaner and more durable, especially during autumn and winter when leaves are abundant—regular checks are essential.
