Coolant: Service and Repair
2GR-FSE COOLING: COOLANT: REPLACEMENT
1. REMOVE ENGINE UNDER COVER
2. REMOVE V-BANK COVER SUB-ASSEMBLY Removal
3. REMOVE COOL AIR INTAKE DUCT SEAL Removal
4. REMOVE NO. 1 AIR CLEANER INLET Removal
5. DRAIN ENGINE COOLANT
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.
(a) Loosen the radiator drain cock plug.
(b) Remove the radiator cap. Then drain the coolant.
HINT
Collect the coolant in a container and dispose of it according to the regulations in your area.
(c) Loosen the 2 cylinder block drain cock plugs.
(d) Tighten all the plugs.
Torque : 13 Nm (133 kgf-cm, 10 ft-lbf) for cylinder block drain cock plug
(e) Tighten the radiator drain cock plug by hand.
6. ADD ENGINE COOLANT
NOTICE:
Before adding engine coolant, turn the A/C switch OFF.
(a) Add engine coolant.
Standard capacity:
9.1 liters (9.6 US qts, 8.0 Imp. 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).
* 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.
Slowly pour coolant into the radiator reservoir until it reaches the FULL line.
(b) Install the reservoir cap.
(c) Press the No. 1 and No. 2 radiator hoses several times by hand, and then check the coolant level.
If the coolant level is low, add coolant.
(d) Install the radiator cap.
(e) Start the engine and warm it up until the thermostat opens.
NOTICE:
Before starting the engine to warm up the engine, turn the A/C switch OFF.
HINT
The thermostat open timing van be confirmed by pressing the inlet radiator hose by hand, and checking when the engine coolant starts to flow inside the hose.
(1) Maintain the engine speed at 2,000 to 2,500 rpm and warm up the engine until the cooling fan operates.
NOTICE:
* Make sure that the radiator reservoir still has some coolant in it.
* Pay attention to the needle of the water temperature meter. Make sure that the needle does not show an abnormally high temperature.
* If there is not enough coolant, the engine may burn out or overheat.
* Immediately after starting the engine, if the radiator reservoir does not have any coolant, perform the following: 1) stop the engine, 2) wait until the coolant has cooled down, and 3) add coolant until the coolant is filled to the FULL line.
* Run the engine at 2,000 rpm until the coolant level has stabilized.
(f) Press the No. 1 and No. 2 radiator hoses several times by hand to bleed air.
NOTICE:
* Wear protective gloves.
* Be careful as the radiator hoses are hot.
* Keep your hands away from the fan.
(g) Stop the engine, and wait until the engine coolant cools down to ambient temperature.
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.
Check that the coolant level is between the FULL and LOW line.
If the coolant level is below the LOW line, repeat all of the procedures above.
If the coolant level is above the FULL line, drain coolant so that the coolant level is between the FULL and LOW line.
