coolant loss and alot of it but no puddle?

[suprra_girl]

get in there and look real good
are there signs of water dripping on the a/c radiator or intercooler if it has one

is it coming out of your overflow bottle?

check underneath the intake manifold, near the back above the starter is a water line which feeds the idle speed controller along with the throttle body which then plugs to the front of the intake manifold
check your hoses going to your turbo (if you have one) check the hoses at the back of the motor from the union bolt to the heater pipes
