ok, i dont know whats happening. im losing the coolant but its not boiling, its drinking it all, but there is no coolant smell, and it passes the bubble test. i cant sind any leaks either. where is it going?
my last engine died of coolant seal failure, and this isnt showing any of the signs, but im loosing it at a rate of about 1 gallon per tank almost. wtf?

It's sneeking out somewhere.

Maybe go to a higher percent anti-freeze so the leak smell will be stronger.

See if its dumping it into the overflow bottle, and then out the top of that. Mine seems to lose coolant somewhere when i turn on the heater, but only then

mine turned out to be a bad water pump. the odd bit is the weep hole was dry! it had to be parked for a few days to see the drips on the ground.

proper thing to do is to pressure test. you pressurize the system and see where the leak(s) are

Well mine did... i had to suckout a Pool of Collant from under the carpet and whats worse the Collant was "Cold" so i couldn't smell it maybe beacuse it had more water mixed than Collant.
