Thermostat -- Installation |
| 1. INSTALL THERMOSTAT |
Install a new gasket onto the thermostat.
Install the thermostat with the jiggle valve upward.
- HINT:
- The jiggle valve may be set to within 10° on either side of the prescribed position.
 |
| 2. INSTALL WATER INLET |
Install the water inlet with the 2 nuts.
- Torque:
- 9.0 N*m{92 kgf*cm, 80 in.*lbf}
 |
| 3. CONNECT RADIATOR HOSE OUTLET |
Install the clamp and connect the radiator hose outlet.
 |
| 4. ADD ENGINE COOLANT |
Close the radiator drain cock plug and 2 cylinder block drain cock plugs.
- Torque:
- 13 N*m{130 kgf*cm, 9 ft.*lbf} for cylinder block drain cock plug
Slowly fill the radiator with TOYOTA Super Long Life Coolant (SLLC).
- Specified capacity:
- 6.2 liters (6.6 US qts, 5.5 lmp. qts)
- 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).
- Contact your TOYOTA dealer for further details.
Slowly pour coolant into the radiator reservoir tank 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 sub-assembly and reservoir tank cap.
Start the engine, and warm it up.
- HINT:
- Adjust the air conditioner set temperature to MAX (HOT).
Stop the engine, and wait until the engine coolant cools down.
Add engine coolant to the FULL line on the radiator reservoir.
| 5. CHECK FOR ENGINE COOLANT LEAKS |
 |
- 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*cm, 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.
