Hey so i was driving and this big puff of steam erupts from my hood and engine temp quickly shoots up. the steam is coming from the back near the battery so i think the heater hoses ripped (i changegd both rad hoses this month and they seem fine still) does anyone know the part number or what item i need to buy? The writeup for this problem seems to have lost its pictures, any suggestions, can i do it myself? or should i have a mechanic do it?
