Hi guys, just to make my long story short...

how many of you had experienced your coolant keeps on draining no matter how many times you refill it. I already had a water pump, radiator hose, and radiator replaced. I can't think of why my coolant keeps on draining. I drove my car 2-3 times a week.. maximum 2hrs and the coolant drained to the bottom of the bottle. I know there is something wrong, but can't figure out what. Maybe you guys can help me out, the auto shop charge around $100 just to diagnose it.
