well the t-wagon stranded me this morning when she over heated. she's losing water but not leaking it so i figure she is drinking it. any suggestions would be helpful.

check your radiator cap. sounds just like what my wagon was doing. no coolant puddles, no steam from tail pipe, no water in oil, but was drinking water like crazy.

What year is the T-Wag? It's probably the head gasket, but there is a little cooling hose under the turbo that could be leaking. This happened to me once. The water was leaking onto the downpipe or the block and boiling away so I never saw it drip to the ground.
