my 93 touring has a leak on the very right front (underneath the car) of the car

it seems some type of green liquid is comming out through the crack in some sort of box or container

can someone tell me what that is and if its a big boo boo, and how to fix =\

help asap <3

 

green liquid = anti-freeze

sound liks a cracked overfill tank
need to fix it, it will lower the pressure in you cooling system and make your car overheat

 

i just bought some anti-freeze because i believe the whole tank was empty.

where is the hole in which i fill this stuff up.

and how much would it cost to fix the crack, and if its possible i can do it myself
