Oldsmobile/Buick Repair: severe coolant leak, buick skylark, coolant leak

Question
I've had a small crack in the plastic casing of my radiator that has forced me to check the fluid levels every time I drive my '98 buick skylark. My most recent problem involves the complete dumping of every drop of fluid I put into it by way of a small metal pipe with a rubber "L" shaped tube on the end of it. It is located on the passenger side of the car by the firewall. Why would a supposedly "closed system allow the water/fluid to drain directly out of the car as fast as I put it in? Do I need to check my heater core for a hole? HELP!! I need to be able to get to work!!!!

Answer
hello deboraha
it is a heater core the l shaped tube is part of the heater core theire is a rubber hose and that is called heater hose . maybe that is a break in it which is only about 30 dollors at a shop to change . sounds like bad hose good luck to u hun and u have a pretty name pete
