Where is the sunroof drain hole located on the Mazda6?
2 Answers
The sunroof drain holes are located at the A-pillar and C-pillar positions of the vehicle. In addition, the car also has air conditioning drain holes, engine compartment drain holes, door drain holes, fuel tank drain holes, and exhaust pipe drain holes. Air conditioning drain hole location: The air conditioning drain hole is generally located under the co-driver's side on the vehicle chassis, where a hose directs the condensed water from the air conditioning system downward. Engine compartment drain hole location: The engine compartment drain holes are situated on both sides of the windshield wipers, with rain water being channeled out through drainage grooves in the engine bay. Door drain hole location: Door drain holes are positioned at the bottom of the door panels. Typically, each door has two drain holes to ensure timely drainage even if one becomes clogged. Fuel tank drain hole location: The fuel tank drain hole is located inside the fuel filler cap, designed to drain any residual liquids accumulated during refueling.
I've been driving my Mazda6 (known as Rui Yi in China) for five years, and the sunroof drainage holes are mainly located at the four corners of the sunroof frame. To be more specific, you'll find small circular holes, usually made of plastic, along the front, rear, left, and right edges of the roof sunroof. These holes connect to drainage hoses that extend to below the doors or near the wheel arches, where water drains out. This design prevents rainwater or dew from accumulating in the sunroof channels, which could otherwise leak into the car, wetting the seats or carpets, and over time, corroding electrical wiring. I've noticed that sunroof maintenance is often overlooked but is really important, especially during the rainy season or when parking under trees, as leaves and dust can easily clog the holes. You can use a soft air pump to blow out the holes or clean them with a thin wire—doing this once a year is sufficient. Remember, these holes are hidden but have a big impact; failing to address blockages promptly can lead to moldy interiors or damaged control panels, which are quite troublesome to repair.
