- [SA\-026\-26](/bulletins/11032101.md), 2026-05-05, Service bulletin: ENGINE. This Service Alert supersedes the previously issued M\-Tip\(s\) listed below. The changes are noted in Red text. MT\-002/19 09/30/19 and 12/19/19 DESCRIPTION If an engine assembly is replaced after a catastrophic internal mechanical failure, clean the intake manifold internally before installing a replacement engine assembly. If the intake manifold is not cleaned properly, the replacement engine may fail prematurely. Metallic debris from the old engine \(with catastrophic internal mechanical failure\) may rest inside the intake manifold. When the new engine assembly is installed, debris in the intake manifold will be ingested into the new engine and cause internal damage. Clean the intake manifold internally to remove any debris from old engine before installing the new replacement engine assembly. If the intake manifold cannot be properly cleaned internally, replace it.

Interior parts made of resin have antistatic coating to prevent dust from sticking on the surfaces, and depending on the conditions of use, the antistatic components may crystallize slightly, giving an appearance of white stains on the surface. To remove the stains, wipe the stained surface with a towel soaked with water mixed with a small portion of a neutral detergent. If the white stains reappear again, simply wipe them again in the same way. NOTE: The antistatic effect does not deteriorate with this procedure.
