Precaution for Liquid Gasket

INFOID:0000000007541125

LIQUID GASKET APPLICATION PROCEDURE

Remove old liquid gasket adhering to the liquid gasket application surface and the mating surface.
• Remove liquid gasket completely from the liquid gasket application surface, mounting bolts, and bolt

holes.

Wipe the liquid gasket application surface and the mating surface with white gasoline (lighting and heating
use) to remove adhering moisture, grease and foreign materials.

Apply liquid gasket to the liquid gasket application surface.
Use Genuine RTV Silicone Sealant or equivalent. Refer to

GI-22, "Recommended Chemical Prod-

ucts and Sealants"

• Within 5 minutes of liquid gasket application, install in the mating component.
• If liquid gasket protrudes, wipe it off immediately.
• Never retighten mounting bolts or nuts after the installation.
• After 30 minutes or more have passed from the installation, fill engine oil and engine coolant.
