Cooling system, loss of coolant

[Grey_Ghost]

Last week, I swapped the water in my cooling system that was originally coolant, back to coolant, after solving the no-pressure, and what I thought was coolant loss.

I bled the car, through the cap and the thermostat housing. Until today the level hadn't really changed.

I came up the steep hill near my place, and the car hesitated at the top once. (It is an 8% grade. It is 30 degrees. I was doing full load up the hill)
It ran fine going down the hill, then into my driveway.

It's used this much coolant today. The system held pressure. I did rebleed it in case it was that, I got large bubbles in the radiator.

It's being slightly noisier than last week, but this particular motor is whisper quiet.

Did you clamp off the heater core pipes when you bled the system or vacuum fill the system? Heater cores are notorious for air pockets.
Normally after filling the system recommend revving the shit out of the engine(once its warm) to get the water pump pushing as hard as possible.

Yep. Had heater cranked to maximum when I filled it.

OK. Drained overflow again today. I have had a bottle attached to the outlet. It's not venting the bottle.

Carpets are dry. If it's idling at the lights, I can smell coolant.

Ooo head

edit: does it smell sweet out the exhaust when idling and warm?

It blew out both upper *and* lower radiator hoses today. I'll replace them both, and reassess. They could be a symptom or a cause!

A few weeks, I've been not dallying it. I'm going through about a litre every 1000km, as in, I need to add water when I add petrol.
