A little bit will escape, but not a whole lot. If you've dropped the level of coolant in your surge tank it likely is just the result of air pockets being passed thru (and the air pockets being replaced by coolant). No matter how carefully you burp the system, you always get a few pockets of air here, there, the heater, etc., that work their way through the system as you drive the car (it can take months). Just keep an eye on it -- I fill mine to about an inch above the hole at the bottom of the tank. If you have no puddles under your car, your
oil does not turn to a Nestle Shake type goo, and you have no funky steamy smoke coming out of your pipes then don't even
think that there is anything wrong. You should replace the coolant every three years or so with the good old fashioned conventional green coolant with distilled water from the grocery store. Throw in a bottle of Watter Wetter as well and think no more about it.
