| Capacity | ||||||||
|---|---|---|---|---|---|---|---|---|
|
Note
Do not substitute plain water for engine coolant.
Tech Tips
Use of improper coolants may damage the engine cooling system.
Use only Toyota Super Long Life Coolant or similar high quality ethylene glycol based non-silicate, non-amine, non-nitrite, and 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).
Check the coolant level inside the radiator by squeezing the inlet and outlet radiator hoses several times by hand.
If the coolant level goes down, add coolant.
Install the radiator cap securely.
Slowly pour coolant into the radiator reservoir until it reaches the FULL line.
Warm up the engine until the thermostat opens.
While the thermostat is open, circulate the coolant for several minutes.
Tech Tips
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.
Maintain the engine speed at 2000 to 2500 rpm.
Squeeze the inlet and outlet radiator hoses several times by hand while warming up the engine to bleed the air.
CAUTION:
When squeezing the radiator hoses:
Wear protective gloves.
Be careful as the radiator hoses are hot.
Keep your hands away from the fan.
Stop the engine and wait until the coolant cools down.
Remove the radiator cap and check the coolant level inside the radiator.
If the coolant level is below the full level, repeat the operation until the coolant level remains at the full level.
Check the coolant level inside the radiator reservoir tank again.
If it is below the full level, add coolant.
INSPECT FOR ENGINE OIL LEAK
Warm up the engine and inspect for oil leak.
INSPECT FOR ENGINE COOLANT LEAK
Remove the radiator cap.
CAUTION:
To avoid the danger of being burned, do not remove the radiator cap while the engine and radiator are still hot. Thermal expansion will cause hot engine coolant and steam to blow out from the radiator.
| *1 | Radiator Cap Tester |
Fill the radiator with coolant and attach a radiator cap tester.
Warm up the engine.
Pump it to 118 kPa (1.2 kgf/cm2, 17.1 psi), then check that the pressure does not drop.
If the pressure drops, check the hoses, radiator and water pump for leakage. If there are no signs of external coolant leakage, check the heater core, cylinder block and head.
Reinstall the radiator cap.
INSPECT FOR FUEL LEAK
INSPECT FOR EXHAUST GAS LEAK
CHECK ENGINE OIL LEVEL
Warm up the engine, stop the engine and wait 5 minutes.

| *1 | Intelligent Tester |
When using the intelligent tester:
Connect the intelligent tester to the DLC3.
Turn the ignition switch to ON.
Select the following menu items:
Powertrain / Engine and ECT / Data List / Engine Speed.
Tech Tips
Refer to the intelligent tester operator's manual for further information regarding the selection of Data List.
Inspect the engine idling speed.
| Idling speed |
|---|
| 700 to 800 rpm |
Fully depress the accelerator pedal.
Check the maximum speed.
| Maximum speed |
|---|
| 4300 to 4600 rpm |
Turn the ignition switch to OFF.
Disconnect the intelligent tester from the DLC3.
When not using the intelligent tester:
Install SST to terminal 9 (TAC) of DLC3, then connect a tachometer.
Note
Examine the terminal numbers before connecting them. Connecting the wrong terminals can damage the engine.
Turn the ignition switch to ON.
Inspect the engine idling speed.
| Idling speed |
|---|
| 700 to 800 rpm |
Fully depress the accelerator pedal.
Check the maximum speed.
| Maximum speed |
|---|
| 4300 to 4600 rpm |
Turn the ignition switch to OFF.

Note
In order to avoid shorting the circuit of the wire harness connected to the glow plug No. 1 connector, wrap vinyl tape around the wire harness terminal portion.
Disconnect all the connectors from the 4 injector.
Connect the cable to negative battery terminal.
Crank the engine to remove foreign objects before measuring the compression.
Install SST into the glow plug hole.
Connect a compression gauge to SST.
While cranking the engine, measure the compression pressure.
| Standard pressure |
|---|
| 2000 kPa (20.1 kgf/cm2, 290 psi) |
| Minimum pressure |
|---|
| 1630 kPa (16.6 kgf/cm2, 236 psi) |
| Difference between each cylinder |
|---|
| 500 kPa (5.0 kgf/cm2, 71 psi) or less |
Note
Use a fully-charged battery so that the engine speed can be increased to 250 rpm or more.
Inspect the other cylinders in the same way.
Measure the compression pressure in as short a time as possible.
If the cylinder compression is low, pour a light coat of engine oil into the cylinder through the glow plug hole, then inspect it again.
Tech Tips
If adding oil increases the compression, the piston rings and/or cylinder bore may be worn or damaged.
If the pressure stays low, a valve may be stuck or seated improperly, or there may be leakage from the gasket.
Remove the compression gauge and SST.
Disconnect the cable from the negative battery terminal.
Connect all the connectors to the 4 injectors.
Install the 4 glow plugs Click here.
