INFOID:0000000003793184
INSPECTION AFTER REMOVAL
1. Check valve seating condition at ordinary room temperatures. It should seat tightly.
2. Check valve operation.
 If the malfunctioning condition, when valve seating at ordinary
room temperature, or measured values are out of the standard,
replace water inlet and thermostat assembly.
INSPECTION AFTER INSTALLATION
 Check for leakage of engine coolant using the radiator cap tester adapter (commercial service tool) and the
radiator cap tester (commercial service tool). Refer to CO-8, "
Inspection".
 Start and warm up the engine. Visually check that there is no leakage of engine coolant. Thermostat (Standard) : Refer to CO-27, "
Thermostat".

scheduled maintenance.
2. Open engine hood and check the following:
- Harness connectors for improper connections
- Wiring harness for improper connections, pinches and cut
- Vacuum hoses for splits, kinks and improper connections
- Hoses and ducts for leaks
- Air cleaner clogging
- Gasket
3. Confirm that electrical or mechanical loads are not applied.
- Head lamp switch is OFF.
- Air conditioner switch is OFF.
- Rear window defogger switch is OFF.
- Steering wheel is in the straight-ahead position, etc.
4. Start engine and warm it up until engine coolant temperature
indicator points the middle of gauge.
Ensure engine stays below 1,000 rpm.
5. Run engine at about 2,000 rpm for about 2 minutes under no
load.
6. Check that no DTC is displayed with CONSULT-III or GST.
Are any DTCs detected?
YES >> GO TO 2.
NO >> GO TO 3.
2.REPAIR OR REPLACE
Repair or replace components as necessary according to corresponding Diagnostic Procedure.
>> GO TO 3
3.CHECK TARGET IDLE SPEED
