Yea, I know, you've probably heard this one a million times.

So while waiting for some parts to arrive, I decided I might as well flush the coolant.

I have the cold car up on jacks in the garage with the front about 3 inches higher than the back. I have the vent valve open, the coolant cap loose, 3 hoses underneath disconnected and even the thermostat quite loose, but not removed, just hanging on the 4 very loose bolts.

I turned the ignition switch to run, heater on high and fan on low, per the DIY article, but which, incidentally, didn't seem to do anything at all.

I only collected a total of about 12.6 liters after letting it sit overnight (with minimal splash outside the catch bin) and I checked that the fluid level was basically full before starting any of this.

My expectation was it should be closer to 19 liters per the DIY article.

I'm tempted to pull the thermostat completely and just replace it also, but I really don't expect any more fluid as a result of this, it is quite loose already.

What could I be missing here?
