Zach and I pull out of mcdonalds in his 99 vig 163k. Car didn't over heat but blew antifreeze out of the resivor..and had major pressure build up for about five to ten minutes. We think the head gasket is gone..?? Building up pressure on the water side which pressurized the coolant and blew. Were sitting here at the damn gas station waiting for aaa to get here. F our lives.
