3. Attach liquid gasket tube to the tube presser [SST: WS39930000
(—)].
Use Genuine RTV Silicone Sealant or equivalent. Refer to
GI-48, "
RECOMMENDED CHEMICAL PRODUCTS AND
SEALANTS" .
4. Apply liquid gasket without breaks to the specified location with the specified dimensions.
If there is a groove for the liquid gasket application, apply liq-
uid gasket to the groove.
As for the bolt holes, normally apply liquid gasket inside the
holes. Occasionally, it should be applied outside the holes.
Make sure to read the text of service manual.
Within five minutes of liquid gasket application, install the mat-
ing component.
If liquid gasket protrudes, wipe it off immediately.
Do not retighten after mounting bolts and nuts the installation.
After 30 minutes or more have passed from the installation, fill
engine oil and engine coolant.
CAUTION:

LEVEL CHECK
Check if the reservoir tank engine coolant level is within the
“MIN” to “MAX” when the engine is cool.
Adjust the engine coolant level as necessary.
LEAK CHECK
To check for leaks, apply pressure to the cooling system with the
radiator cap tester (commercial service tool) and radiator cap
tester adapter [SST].
WARNING:
Do not remove radiator cap when engine is hot. Serious
burns could occur from high-pressure engine coolant
escaping from radiator.
CAUTION:
Higher test pressure than specified may cause radiator damage.
NOTE:
In a case that engine coolant decreases, replenish radiator with engine coolant.
If anything is found, repair or replace damaged parts.
Changing Engine CoolantABS004T9
WARNING:
To avoid being scalded, do not change engine coolant when the engine is hot.
Wrap a thick cloth around radiator cap and carefully remove radiator cap. First, turn radiator cap a
quarter of a turn to release built-up pressure. Then turn radiator cap all the way.
DRAINING ENGINE COOLANT
1. Remove front engine undercover with power tool.
2. Open radiator drain plug at the bottom of radiator, and then remove radiator cap.
When draining all of engine coolant in the system, open water drain plugs on cylinder block. Refer
to EM-123, "
DISASSEMBLY" .
3. Remove reservoir tank as necessary, and drain engine coolant and clean reservoir tank before installing.
