How to Flush the Radiator in a Mazda6
by Editorial TeamThe radiator is the heart of a vehicle cooling system and to keep it running at optimum efficiency in your Mazda6, you should perform some routine maintenance, including flushing of the radiator. While this may seem like a complicated task, it's relatively simple and nearly anyone can do it.
Step 1
Move the Mazda6 to a level surface, switch off the engine and set the parking brake. Then, open the hood and check the external temperature of the radiator. If it's hot or warm to the touch, allow it to cool down before you proceed.
Step 2
Twist the radiator cap one full revolution and then step away from it. This allows any internal pressure to escape. After waiting a minute or so, completely remove the radiator cap.
Step 3
Place a bucket or tray with at least a two-gallon capacity underneath the radiator and below the drain plug. The drain plug on the Mazda6 is underneath the radiator on the driver's side of the car.
Step 4
Unscrew the drain plug and allow the old coolant to flow into bucket. Because of the drain plug location on the Mazda6, you may want to wear goggles to protect your eyes from coolant splash and gloves for your hands, since the coolant is very toxic.
Step 5
Put the drain plug back into place and fill the radiator completely with distilled water. Remove the plug to flush the water and repeat until the water runs debris free out the radiator drain. Once complete, be sure to dispose of the radiator flush correctly.
Step 6
Tighten the drain plug and fill the radiator with fresh coolant. Stop filling when the coolant is within an inch from overflowing from the radiator.
Step 7
Start the engine of the Mazda6 and turn the heater on the highest setting. Allow the car to run for about 10 minute and then shut off the engine. Check the coolant level and add more, if necessary. Finally, put the radiator cap back on and close the hood.

- Bucket
- Sealable container
