Exactly, I will be writing a DIY for the general maintenance flushes.
What you will need
A few gallons of distilled water. (I'd buy 5 because i like to really flush my systems lol).
Garden hose (new) about 4 feet of it sectioned off and cut.
A radiator hose clamp kit - you can by one at walmart for like 4 dollars

A phillips head screw driver
The mental capacity to turn a screw driver left (lol)
Reference your manual or retrieve a .pdf copy of the manual via our facebook page. You need to know what the radiator look like and where the lower hose is located.
What you do is simple remove the bottom of the lower hose off of its existing clamp.
(to remove the clamp you need to unscrew the phillips screw keeping it tight.)
That way its connected to the radiator but it is dangling at free will.
You simply let the current fluid drain out of the lower hose *please contain it in a drain pan because its toxic and animals like the taste and smell

*
Use the garden hose section for your gallons of distilled water, and possibly another section to help with the draining on the lower hose if your drain pan doesn't have a nice handle. Pour in the distilled water and allow that to drain out. Repeat until the water runs clear. Simple. Simple. Simple.
Id reccomend replacing all the current clamps on your hoses with the new clamps from that kit you got from walmart. Thats almost as important as checking your radiator hoses. faulty clamps lead to fluid leaks. just like a cracked hose.
Refill with engine coolant. Most require a 50/50 combo of water to coolant.
The last step is removing the radiator cap and allowing your engine to idle with the fresh coolant put into the engine coolant container. This will just help push and unwanted air out. Do this for like 5 minutes.
Incase you didnt know, like myself when I started out DIY, the radiator is the equivalent of engine coolant system. People use it interchangeably on products and when speaking. It took me a while to figure that out on my own lol.
Please don't buy a coolant flush machine. Just use distilled water, not regular as the particulates in regular may or may not harm the system.
