[DaLe five OH!]

i flushed my rad a few months ago when i changed my timing chain, and now all of the coolant is gone from the overflow tank...theres no white smoke what so ever so its not burning it...and it cant be leaking it because they would have thrown me off the track friday night when i was running, and theres no puddles when i park it and come back 20min or so later...where the heck is it goin??
