Help! I've got an interior leak.
 

I just bought a 67 mustang and I was flushing out the radiator because it was pretty rusty. After 10 minutes of driving it around with the cleaner in it, liquid started leaking into the car on the passenger side floorboard. Has anyone else had this problem? What could have caused this and how do I fix it? Please help!!!!

You either have a loose heater hose or the heater core is leaking. Not a very difficult or expensive fix. Go to any of the aftermarket supplier like www.mustangsplus.com or www.mustangsunlimited.com and get a new core. I have doubt it is the hoses.
