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.

Warranty Compliance Note: Mazda’s Warranty Policy does not cover damage to the replacement engine if the intake manifold was not cleaned properly.
