- Even if air bleeding using the hand pump has been completed, the starter may need to be cranked for 10 seconds or more to start the engine.
- Do not crank the engine continuously for more than 20 seconds. The battery may be discharged.
- Use a fully-charged battery.
When the engine can be started, proceed to the next step.

- NOTICE:
- Never use water as a substitute for engine coolant.
- HINT:
- TOYOTA vehicles are filled with TOYOTA SLLC at the factory. In order to avoid damage to the engine cooling system and other technical problems, only use TOYOTA SLLC or similar high quality ethylene glycol based non-silicate, non-amine, non-nitrite, 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).
- Please contact your TOYOTA dealer for further details.
Press the inlet and outlet radiator hoses several times by hand, and then check the level of the coolant.
If the coolant level drops below the B line, add TOYOTA SLLC to the B line.

- CAUTION:
- When pressing the radiator hoses:
- Wear protective gloves.
- Be careful as the radiator hoses are hot.
- Keep your hands away from the radiator fan.
Stop the engine and wait until the coolant cools down to ambient temperature.
- CAUTION:
- Do not remove the radiator reservoir cap while the engine and radiator are still hot. Pressurized, hot engine coolant and steam may be released and cause serious burns.
After the coolant cools down, check that the coolant level is at the F line.
If the coolant level is below the F line, add TOYOTA SLLC to the F line.
22. INSPECT FOR COOLANT LEAK |
- CAUTION:
- Do not remove the radiator reservoir cap while the engine and radiator are still hot. Pressurized, hot engine coolant and steam may be released and cause serious burns.
- NOTICE:
- Before each inspection, turn the A/C switch off.
Fill the radiator with coolant and attach a radiator cap tester.
Warm up the engine.
Using the radiator cap tester, increase the pressure inside the radiator to 118 kPa (1.2 kgf/cm2, 17 psi), and check that the pressure does not drop.
If the pressure drops, check the hoses, radiator and water pump for leaks. If no external leaks are found, check the heater core, cylinder block and head.
23. INSPECT FOR FUEL LEAK |
- CAUTION:
- During Active Test mode, the engine speed becomes high and the combustion noise becomes loud, so pay attention.
- During Active Test mode, the fuel pressure becomes high. Be extremely careful not to expose your eyes, hands, or body to escaping fuel.
Check that there are no leaks from any part of the fuel system when the engine is stopped. If there is fuel leakage, repair or replace parts as necessary.
Start the engine and check that there are no leaks from any part of the fuel system. If there is fuel leakage, repair or replace parts as necessary.
