Tech Tips
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 and technology consists of a combination of low phosphates and organic acids).
Please contact your TOYOTA dealer for further details.
Note
Never use water as a substitute for engine coolant.
Press the inlet and outlet radiator hoses several times by hand, and then check the level of the coolant.
Install the radiator cap.
Bleed air from the cooling system.
Warm up the engine until the thermostat opens. While the thermostat is open, circulate the coolant for several minutes.
Maintain the engine speed at 2,000 to 2,500 rpm.
Press the inlet and outlet radiator hoses several times by hand to bleed air.
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 cap while the engine and radiator are still hot. Pressurized, hot engine coolant and steam may be released and cause serious burns.
Check the coolant level in the radiator reservoir.
If the coolant level is low, add SLLC to the reservoir F line.
CHECK FOR ENGINE COOLANT LEAKS
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 the radiator cap tester, increase the pressure inside the radiator to 118 kPa (1.2 kgf/cm2, 17.1 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 cylinder block and head.

INSPECT CO/HC
Tech Tips
This check is for determining whether or not the idle CO/HC complies with regulations.
Start the engine.
Keep the engine speed at 2,500 rpm for approximately 180 seconds.
Insert CO/HC meter testing probe at least 40 cm (1.3 ft.) into the tailpipe during idling.
Immediately check CO/HC concentration at idle and/or 2,500 rpm.
Tech Tips
When performing the 2 mode (2,500 rpm and idle) test, follow the measurement order prescribed by the applicable local regulations.
If the CO/HC concentration does not comply with regulations, troubleshoot in the order given below.
Check the A/F sensor operation and heated oxygen sensor operation.
See the table below for possible causes, then inspect and correct the applicable causes if necessary.
CO | HC | Symptom | Causes |
---|---|---|---|
Normal | High | Rough idle | 1. Faulty ignitions:
2. Incorrect valve clearance 3. Leaky intake and exhaust valves 4. Leaky cylinder |
Low | High | Rough idle (Fluctuating HC reading) |
1. Vacuum leaks:
2. Lean mixture causing misfire. |
