If it leaking inside, check the heater core/hose fitting

Your post is confusing, are you leaking water/(not coolant) on floor from a plugged up ac evaporator drain? If so, the A/C drain (short little tube that drains, is behind the engine just below the alternator. If that is what your talkinh about.

The heater hose starts at the engine side both in and out hoses then goes thru the firewall to the heater core. Now if you are talking about the AC drain tube-I dunno where it is-sorry-If its the AC drain its not gonna be coolant -heater core will be antifreeze/coolant
