I bought this 93 ex for 350 the other day and I just replaced the battery and turned it on, and after a while I noticed that water started pouring in down by the pedals... Im thinking its the heater core, right? (the water was hot and had coolant in it, so i know it was the water used to heat the car, going into the heater core)

 

I decided to just take my dash apart and see where it was leaking from, turns out it was the heater core, which was a bitch to get to btw... For future reference whenever you got coolant inside the car or it hasn't rained in a long time and your carpets wet, your heater core's leaking, and it takes a shitload of work to get to it... fun
