Precautions for Liquid Gasket

ABS000P2

REMOVAL OF LIQUID GASKET SEALING

●

After removing the mounting bolts and nuts, separate the mating
surface using the seal cutter (SST) and remove the liquid gasket
sealing.

CAUTION:

Be careful not to damage the mating surfaces.

●

In areas where the seal cutter (SST) is difficult to use, use a
plastic hammer to lightly tap (1) the seal cutter where the liquid
gasket is applied. Use a plastic hammer to slide the seal cutter
(2) by tapping on the side.

CAUTION:

If for some unavoidable reason a tool such as a flat-bladed
screwdriver is used, be careful not to damage the mating
surfaces.

LIQUID GASKET APPLICATION PROCEDURE

1.

Using a scraper, remove the old liquid gasket adhering to the
gasket application surface and the mating surface.

●

Remove the liquid gasket completely from the groove of the
liquid gasket application surface, mounting bolts, and bolt
holes.

2.

Wipe the gasket application surface and the mating surface
removing any adhering moisture, grease and foreign material.

3.

Attach the liquid gasket tube to the tube presser (SST).
Use Genuine RTV Silicone Sealant or equivalent. Refer to

GI-46, "RECOMMENDED CHEMICAL PRODUCTS AND SEAL-
ANTS"

.

4.

Apply the liquid gasket without breaks to the specified location
with the specified dimensions.

●

If there is a groove for the liquid gasket application, apply the
liquid gasket to the groove.

●

As for the bolt holes, normally apply the gasket inside the
holes. Occasionally, it should be applied outside the holes.
Make sure to read the text of this manual.

●

Within five minutes of liquid gasket application, install the mat-
ing component.

●

If the liquid gasket protrudes, wipe it off immediately.

●

Do not retighten after the installation.

●

Wait 30 minutes or more after installation before refilling the
engine with oil and coolant.

CAUTION:

If there are specific instructions in this manual, observe
them.
