Add engine coolant.
- Specified capacity:
- 9.1 liters (9.6 US qts, 8.0 lmp. qts)
- HINT:
Slowly pour coolant into the radiator reservoir until it reaches the FULL line.
Press the inlet and outlet radiator hoses several times by hand, and then check the level of the coolant.
If the coolant level is low, add coolant.
Install the radiator cap and reservoir cap.
Bleed air from the cooling system.
- NOTICE:
- Before starting the engine to warm up the engine, turn the A/C switch OFF.
Warm up the engine until the thermostat opens. While the thermostat is open, circulate the coolant for several minutes.
- HINT:
- 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.
- NOTICE:

- NOTICE:
- Before performing each inspection, turn the A/C switch OFF.
- CAUTION:
- Do not remove the radiator cap while the engine and radiator are still hot. Pressurized, hot engine coolant and steam may be released and cause serious burns.
Fill the radiator with coolant and attach a radiator cap tester.
Warm up the engine.
Using a 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 cylinder head.
