Exhaust Manifold And Air Lines Groups Changed To Prevent Exhaust Leakage
Usage:
3408 Truck Engines
Description of Change: New exhaust manifold groups and air lines groups are used on the above models. The new groups use manifolds and stainless steel tubes with slip-joints instead of the former flanges with gaskets. These changes in manifold design will prevent leakage of exhaust gas at the manifold-to-air lines connection at the rear of the engine.
Adaptable As: Direct replacement when the new parts are used together.
