| Re: Mystery Coolant Leak I am sitting in the exact same position, with my Catera. I have removed the Intakes, and there are no visible leaks in the V or from the coolant pipe O-Ring. I am sitting at the same position of next trying to remove the heat shield to see. I hope it is not the head gasket either but what else is in there. Could there be a Frost plug? Any Idea's would be greatly appreciatted. As i dont think that heat shield is going to be an easy job |
