Where are the drainage holes on the Mazda6?

The Mazda6 has drainage hole plugs located on both sides of the side sills, each with several footpad covers. Below are some relevant maintenance tips for the Mazda6: 1. Check the antifreeze: The antifreeze level must be appropriate. Service stations recommend replacing antifreeze every two years, but mixed antifreeze (especially if water has been added during summer) must be replaced annually. Note that different brands and models of antifreeze should not be mixed. Next is the engine oil. Winter places higher lubrication demands on the car, so if summer-grade oil is being used, it must be replaced. Oil that has been used for a long time, turned black, or lost its adhesive properties should also be replaced to ensure smooth engine starts. 2. Use higher-octane gasoline: If you normally use 90-octane gasoline, consider switching to 93-octane. Because winter driving environments have lower temperatures, higher-octane gasoline has a higher ignition point and provides slightly better starting performance.
As a seasoned Mazda6 driver for many years, I know the drainage hole locations all too well. The main ones are around the sunroof – when you open it, you'll spot small round holes at each corner. Rainwater flows through these into thin tubes that channel it beneath the chassis to prevent cabin leaks. If skeptical, gently run your finger along them; the rear sunroof holes clog most easily since rain and debris accumulate there. Last year, a blockage caused my footwell to flood, costing ¥1,500 in repairs. My advice: inspect them regularly, especially before rainy seasons, using a soft brush or compressed air. Door bottoms also have drainage holes along the lower edge seams (visible when crouching) to release pooled water. Even the trunk lid opening has small weep holes to prevent water buildup. Keeping these passages clear is absolutely crucial – it saves major repair costs.
As a young Mazda6 owner who commutes daily, drainage hole issues are quite common. The locations are simple: first, check the small holes at the four corners when the sunroof is open—those are the main drainage holes; then look at the bottom of the doors, where there are cleverly designed gaps for water to escape; the trunk area might also have small holes. I once neglected to clean them before the rainy season, resulting in water seeping into the car and damaging the seats. Normally, you can use a hairdryer on low setting to blow out debris and prevent clogs, but don’t use too much force to avoid damaging the tubes. Remember to check and clean them during routine vehicle inspections—it’s safe and hassle-free, especially to prevent water accumulation that could cause short circuits when driving at night.
