and it tastes like chicken. seriously though. 90 Volvo 740 with B234F engine. Wetness under passenger mat, but smells like water, no hint of antifreeze. Rubbed my hand over the carpet and smelled me fangers to make sure. If it is the heater core, the cost of the repair will exceed the value of the car. I need a jb weld solution. What do you think of Blue Devil Sealer ?
