LIQUID GASKET APPLICATION PROCEDURE
NMLC0001
1.
Use a scraper to remove all traces of old liquid gasket from
mating surfaces and grooves. Also, completely clean any oil
from these areas.
2.
Apply a continuous bead of liquid gasket to mating surfaces.
(Use Genuine Liquid Gasket or equivalent.)
I
For oil pan, be sure liquid gasket diameter is 4.0 to 5.0 mm
(0.157 to 0.197 in).
I
For areas except oil pan, be sure liquid gasket diameter is 2.0
to 3.0 mm (0.079 to 0.118 in).
3.
Apply liquid gasket around the inner side of bolt holes (unless
otherwise specified).
4.
Assembly should be done within 5 minutes after coating.

Wait at least 30 minutes before refilling engine oil and engine
coolant.
