Hey I have a hole under my heater core box I guess its called does anyone know what is envolved in takin out that box???

Is it air conditioned? If it is, it's a pain. Try patching it.

No it dosent have air conditioning but I have tried to get it out and it looks like I will have to dissasemble a whole bunch of stuff to get it bu i might be able to patch it how it is if im carfull. Do u think I would have to use sheet metal and weld a new piece in or could I try and use fiberglass??
