Re: Coolant level slowly dropping
thanks for the detailed reply! I will check the hose to the overflow bottle, but i am sure there is enough pressure, as when I take the cap off, I get the sort of back pressure sound coming from the overflow, kind of like the coolant is rushing back to the bottle.
Funny you mention the thermostat, as I just replaced it last week, as well as flushing the radiator etc. And have nice new gylcol in the system.
I would love to know what the brand of non-glycol coolant you mentioned.
I have had the heater on a fair bit lately and have not had that radiator smell come through, so I pretty much discounted the heater core.
I will take your advice and get the whole system pressure tested at a cooling system place, good call there.
