Where are the drainage holes on the Mazda6?

[MicahRose]

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.
