| 1. INSPECT FOR COOLANT LEAK |
- ПРЕДОСТЕРЕЖЕНИЕ:
- To avoid being burned, do not remove the radiator reservoir cap while the engine and radiator are still hot. Thermal expansion may cause hot engine coolant and steam to blow out from the radiator.
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 123 kPa (1.3 kgf/cm2, 18 psi), and check that the pressure does not drop.
If the pressure drops, check the hoses, radiator or water pump for leaks. If no external leaks are found, check the heater core, cylinder block, and cylinder head.
| 2. INSPECT ENGINE COOLANT LEVEL |
Check that the engine coolant level is between the LOW and FULL lines when the engine is cold.
If the engine coolant level is low, check for leaks and add TOYOTA Super Long Life Coolant (SLLC) or similar high quality ethylene glycol based non-silicate, non-amine, non-nitrite and non-borate coolant with long-life hybrid organic acid technology to the FULL line.
- ПРИМЕЧАНИЕ:
- Do not substitute plain water for engine coolant.
| 3. INSPECT ENGINE COOLANT QUALITY |
Remove the radiator cap.
- ПРЕДОСТЕРЕЖЕНИЕ:
- To avoid being burned, do not remove the radiator reservoir cap while the engine and radiator are still hot. Thermal expansion may cause hot engine coolant and steam to blow out from the radiator.
Check if there is any excessive deposits of rust or scale around the radiator cap and radiator filler hole. The coolant should be free from oil.
If excessively dirty, clean the coolant passage and the coolant.
Install the radiator cap.
