Found some deep rust on my passenger floor board that had made its way through so I decided to cut the small section out and grind the rest of the surface rust down and coat it with some Crc until I could have a new piece welded in. Of course accidentally while I was cutting I nicked the metal water line that is under the passenger floorboard near the door which is spewing coolant. Can someone please help me figure out where to find this line and how to replace it ? Can’t believe I did it. Thanks.
