Buy it, use it then sell it on ebay. Pressurizing your system will tell you in minutes where the problem lies.

Ignore the obvious advice and keep posting otherwise.

Thanks. A number of people have suggested this.

But.....This morning on a stone cold car, I went to pour in some distilled water and it immediately comes out the overflow hose above the right rear tire.

Does this mean the tank is bad?
When the previous tank went bad, the trunk was flooded with coolant.
Most of what I read on these boards says that is the symptom of a bad tank.
But my trunk is dry.
Can they crack or split on the inside of the firewall or in the drain flow path?

I can get a pressure tester from Autozone as a loaner, but it's a $250 deposit and a 2 hour bus ride (No second car)
Or I can buy one as suggested, but is it necessary at this point?

The more I can learn here the better before I do anything else.

I'm a recovering cancer patient, getting low on $$ and need help.

Thank you.
