Tech Tips
Use of improper coolants may damage the engine cooling system.
Use only Toyota Super Long Life Coolant or similar high quality ethylene glycol based non-silicate, non-amine, non-nitrite, and non-borate coolant with long-life hybrid organic acid technology (coolant with long-life hybrid organic acid technology consists of a combination of low phosphates and organic acids).
Check the coolant level inside the radiator by squeezing the inlet and outlet radiator hoses several times by hand.
If the coolant level goes down, add coolant.
Install the radiator cap securely.
Slowly pour coolant into the radiator reservoir until it reaches the FULL line.
Warm up the engine until the thermostat opens.
While the thermostat is open, circulate the coolant for several minutes.
Tech Tips
The thermostat open timing can be confirmed by pressing the inlet radiator hose by hand, and checking when the engine coolant starts to flow inside the hose.
Maintain the engine speed at 2000 to 2500 rpm.
Squeeze the inlet and outlet radiator hoses several times by hand while warming up the engine to bleed the air.
CAUTION:
When squeezing the radiator hoses:
Wear protective gloves.
Be careful as the radiator hoses are hot.
Keep your hands away from the fan.
Stop the engine and wait until the coolant cools down.
Remove the radiator cap and check the coolant level inside the radiator.
If the coolant level is below the full level, repeat the operation until the coolant level remains at the full level.
Check the coolant level inside the radiator reservoir tank again.
If it is below the full level, add coolant.
INSPECT FOR FLUID LEAK
INSPECT FOR OIL LEAK
Warm up the engine and inspect for oil leak.
INSPECT FOR FUEL LEAK
PERFORM ACTIVE TEST
Connect the intelligent tester to the DLC3.
Turn the ignition switch ON.
Turn the intelligent tester ON.
Start the engine.
Enter the following menus: Powertrain / ECD / Active Test.
Perform the Active Test.
| Intelligent Tester Display | Test Details | Control Range | Diagnostic Notes |
|---|---|---|---|
| Test the Fuel Leak | Pressurizes common rail internal fuel pressure, and checks for fuel leaks | Stop/Start |
|
Make sure that there is no fuel leakage in the fuel system during the Active Test.
INSPECT FOR COOLANT LEAK
Remove the radiator cap.
CAUTION:
To avoid the danger of being burned, do not remove the radiator cap while the engine and radiator are still hot. Thermal expansion will cause hot engine coolant and steam to blow out from the radiator.
| *1 | Radiator Cap Tester |
Fill the radiator with coolant and attach a radiator cap tester.
Warm up the engine.
Pump it to 118 kPa (1.2 kgf/cm2, 17.1 psi), then check that the pressure does not drop.
If the pressure drops, check the hoses, radiator and water pump for leakage. If there are no signs of external coolant leakage, check the heater core, cylinder block and head.
Reinstall the radiator cap.
