• Within three minutes following the application, install the cylinder
head onto the cylinder head gasket. Take care not to spread the
sealant beyond the application areas during installation.
CAUTION
• Do not start the engine for at least an hour after installation.
• Whenever the cylinder head bolts are subsequently loos-
