Questions about sensors and how coolant temp works and warned to user?

Hey so I just wanted to confirms some thoughts.

I recently did a coolant flush and refilled the system doing the proper bleeding procedure.

My only worry is I thought 8.5 liters would have been the ammount but I seem to have only put in 6 liters and it's full.

Now I drove the car hard and the system would definitely warn me right if something was wrong? Would it register heat spikes, since we don't have coolant gauge we can't visually see any spikes?

Just want some peace of mind here, and that a flush by draining the rad and disconnecting that hose from the back of the pump won't drain the full 8.5 liters as some still stay in the block?

yeah, the block probably holds quite a bit of coolant. The level sensor will warn you if it's low - if it's working fine I wouldn't worry about it.

You won’t get it all out... heater core and lines, etc.... do the bleed procedure to make sure the air is out and check the level.

And there must be a sensor to if it reaches to high right? Just I hope the sensor ain't like some kind of sensor that triggers when damage is already done haha.

it's right in the coolant reservoir. if it's too full, it will just come out the overflow.

Sorry I meant the temperature reaching to high*.

Like if it's missing some or to much air pockets and there would be a temp spike.

oh, that could be, but there shouldn't be any air pockets after the self bleeding procedure. I think it would show up as a low coolant level first.
