| A101511 2018288- | 2017-10-21. Service bulletin. ENGINE AND ENGINE COOLING. Supersedes Technical Service Bulletin Group 10 number 13-10 dated September 5, 2013. Prior to engine replacement, any debris lodged in transferred assemblies must be removed. If the engine experienced a serious mechanical problem, it is possible that small pieces of metal debris resulting from the mechanical problem may have become deposited in the intake manifold, air intake hoses, exhaust manifolds, exhaust down-pipes, turbocharger, supercharger, and/or intercooler. If these metal debris pieces are not removed prior to the installation and operation of the replacement engine, they could be drawn into the combustion chamber, which can cause a knocking noise and subsequent serious engine damage. |
