A system for reversing heat transfer from an exhaust system assembly on a vehicle comprising an engine block assembly and transaxle assembly operatively connected and located in an engine compartment of an automobile. The system comprises a number one exhaust manifold stay mount, a number two exhaust manifold stay mount, and a front exhaust collector pipe bracket and stay mount. The system comprises an exhaust system with a front exhaust collector pipe located beneath the engine block assembly. The system comprises an engine block assembly heat shield with a cross-section generally comprising the shape of a “U” that is located next to the surface of the engine block assembly. The engine block assembly heat shield is located over and overlays the front exhaust collector pipe bracket and stay mount, the number one exhaust manifold stay mount, and the number two exhaust manifold stay mount.
