Perhaps the cooling fan is running?
Heater inlet hose on a 99 subaru legacy is on the passenger side coming out of the fire wall. One of only 2 hoses coming out of the fire wall.
cause it's junk
You could be low on coolant, a stuck thermostat, engine fan not coming on for starters. If still overheats, I would recommend taking it to a Subaru dealer.
Depending on where you live and what season it is, different dealerships will offer different deals on Subaru's. Make sure to always ask your local dealership if they have any deals/events coming up.
Should be on the Pass. side of dash above your right toe if you are sitting in the seat. 3 or 4 screws and it drops out.
Power going into the pack and none coming out of it. Also a cracking sound as it shorts out.
The Subaru organization is producing top of the line automobiles as usual. For the year 2013 they are coming out with The Impreza, The Outback and the Forrester. Quality automobiles that get great gas mileage and are low maintenance.
I wouldn't have any idea where to start. My recommendation would be to do what I did when my Outback just quit running in my driveway. Call the local garage for a tow truck. This forum doesn't lend itself to the lengthy conversation necessary to narrow in on your problem.

Worn engine parts. Most likely a rod bearing is worn.
