1999 Ford Ranger Heater Core Test??

Hello, I'm guessing I need a new heater core! I have a wet passenger floor and a smell of antifreeze within the cab. Is their any way I can test the heater core to be positive that this is the problem? Can I have a cooling pressure test done? Would that find a small leak in the heater core? I'm guessing it must be small because it has been going on for probably 6 months now and I only need to add about a quart of antifreeze to the radiator. I just wanna be positive it is the heater core, as the labor for this job is like 8 hours according to the local garage. Also, is their anyway I could have done anything to damage my heater core by flushing the coolant system? I had checked the coolant and noticed it was brown. I bought a Prestone do-it-yourself flush kit and flushed and replaced the coolant last fall. Any help is greatly appreciated as usual!! Thanks in advance! Jack

It sounds like your cooling system was neglected, and the rust particles formed a false seal. Sometimes flushing dislodges these particles and then you have a leak. No great loss, a false seal isn't something you want in your system anyhow.
Though your loss rate isn't all that great, a wet floor and antifreeze smell in your cabin isn't good. For one, inhaling antifreeze isn't good for your liver (or is it kidneys?)
I don't think you need much more proof of a leaky heater core than the evidence you presented. Check the hose connections on the outside. Sometimes they leak, and the leak works its way into the heater box. That's about all you can do.

Too add:
These things are a pain in the butt to change. If you plan on having amechanic change it, get ready to take a second mortage out in labor costs. Usually requires the removal of the entire dash board and HVAC assembly.
