| Standard 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).
Loosen the bleeder plug of the outlet housing.
When air is bled and the coolant drains out, firmly tighten the bleeder plug.
Add coolant up to the B line mark in the radiator reservoir and install the reservoir cap.
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.
After the engine cools down, check that the coolant level is between the LOW and FULL level marks.
INSPECT FOR ENGINE COOLANT LEAK
CAUTION:
Do not remove the radiator cap while the engine and radiator are still hot. Hot, pressurized engine coolant and steam may be released and cause serious burns.
Fill the radiator with coolant and attach a radiator cap tester to the radiator.
Warm up the engine.
Using a radiator cap tester, increase the pressure inside the radiator to 137 kPa (1.4 kgf/cm2, 19.9 psi), and check that the pressure does not drop.
Tech Tips
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.
INSPECT FOR EXHAUST GAS LEAK
If gas is leaking, tighten the areas necessary to stop the leak. Replace damaged parts as necessary.
