Hey Grundle sexxy car.
There is a short cut to flushing your cooling system completely. I will write the steps for you.
1. Remove your radiator cap and drain your radiator:
2. Remove your upper radiator hose:
3. Underneath the car, next to the oil filter, there a coolant line which will allow you to remove 95% of your coolant. When you remove the clamp, coolant will flood out.

4. Now, get your favorite water hose and spray water into where the upper radiator hose goes. This will flush out the remaining coolant out of the clamp you just removed from underneath the car.
5. Keep in mind, your cooling system will now hold a small amount of water. Now, pour coolant down the same hole you sprayed water down until the hose underneath the car is flushing out coolant.
6. Connect the hose underneath the car. Screw back in your radiator drain plug, reconnect the upper radiator hose and BLEED your system.
