Once I removed the "Prestone" cap in the picture, I could see inside to an empty hose w/ the puddle I described in an earlier post.. dunno if it helps, hopefully I'm lookin in the wrong hose cause I don't want any more blockages... I've spent almost $500 just trying to get my cooling fixed... atm, it's better than it ever has been, but if that IS the heater hose and it SHOULD have water in it, I'd have to guess that my cooling SYSTEM is still in need of TLC... :\ :'(
