ok, ive installed the sri on my 6 gen civic. i connected the breather hose and the sensor. but running beside the stock breather is another hose. ive done some research and think this is a coolant. right now im running it without it being connected, what do i do with this. everything isrunning fine...for now...engine stays at regular temp, etc. do i really have to drain this. or what? please give me somegood instructions on what to do with this.
