The wife apparently ran over something last night. What ever it was, punctured the rear pass tire and flew up to hit the undercarriage. This morning while replacing the tire, I noticed a small puddle of coolant. I assume that something flew up and hit part of the rear heater system. Does anyone know the part number of the line that runs behind this wheel? Is it metal or rubber? I tried to locate the broken part, but could only see the drip at the lowest part and no cracks. I'd love to get ahold of a parts diagram for that section of the rear heating system.
