Yep, thats what I decided to do. Hope I never have tho replace it.
They have coolant system flush tools available. Flushes the entire system. Vacuum style.
Some can be had for less than $40 US.

That is how most of us do it, dump it out, flush it, and reinstall it.Take it off and turn it upside down?
On some machines, you can take the puke tank tube off of the filler neck and pull it out. Drop the end in a bucket below the tank level and it will drain out.
Or, if you have a pressure test kit, use one of the rubber plugs in the reservoir cap and pressurize it. That'll force the coolant into the radiator. Put the cap on the radiator or you'll have a mess. The same could likely be accomplished with a rag and your hand to seal the reservoir opening.

From the parts drawing it looks as if it lifts straight up, but possibly after releasing the two “locking” tabs . Be advised , I have no direct experience doing this, but what makes sense to me by looking at the drawing.

Here is a cooling system "unsolicited tip"
Way back in the day I was working on a Mercury Sable? ( cant remember exact model, but it was a Ford).
Well anyway they were famous for getting an "air pocket" in the block somewhere when you serviced the cooling system, causing an overheating condition.
Supposedly you had to lift the front of the car like 20 degrees, spin around on your head 3 times, then shake a "magic chickens foot" at it, while chanting magic incantations, in order to get the air pocket out.
Or you could buy a "vacuum filler".
This tool turned out to be awesome when servicing just about any cooling system.
No spills, no waiting forever for the thermostat to open and antifreeze spilling out......
Just hook it up, draw a vacuum using shop air, then stick the tube into your antifreeze bottle and it sucks up the perfect amount of juice every time.
Never over-fills/spills and eliminates any possible air pockets that could develop, and has worked on every cooling system I have worked on to date.
(although I avoid working on cooling systems like the plague, due to the fact that getting ride of antifreeze is harder than trying to get rid of used Plutonium around here....Why is that????)

You just use a dull-tipped prybar, slip it under the tank, and pry up on the back side of the bottom. It will pop right off. Do not pry up in the center of the tank, make sure you are prying under the back edge, where the mounting spade is.
The tank needs to be washed out a couple of times as there usually is sediment in it and stuck to the bottom. This is why you do not just siphon it out.
260,000 miles on my old Ford. Nothing in the bottom of the puke tank. Never been out. If there is sediment in it, you need to flush the cooling system. A lot.
Don't over think things folks. It's just an overflow tank.

$142.80 + tax, for that kit on Amazon ??
I don't think so !
I have this one, but it's not as industrial as the one RWS has. They can be had pretty cheaply. I think I paid about $40 for it. Inflation.....
I bought mine to install an automotive style heater on my Polaris Rzr. Similar situation as RWS. One has to lift the front end or literally hang the Polaris straight up from a tree to get all the air out.... or get one of these. On my Polaris, engine is in the rear. Radiator in the front.

Hahahahah........And worth every penny my friend.....trust me.
(BTW that link was just for demonstration purposes....it might be cheaper somewhere else)
Edit: I just checked my Amazon account and I actually paid $8 more for it in 2017.......Still worth every penny.......
Help! I put my hand in the fire and it hurts...what do I do?Take it off and turn it upside down?
Post the question to anonymous users on the internet of course!
We really need an "app" for that!

If it works, that would certainly seem to make a bit more sense, rather than the one for twice the price, as suggested in post #13.
Certainly not an item for every day use.
