1. Fill the coolant to the top of the radiator neck.
2. Install the radiator cap tester.
3. Create the required pressure in the cooling system and check for coolant leaks.
- Pressure: 93-123 kPa (0.95-1.25 kg/cm²)
If the pressure drops within a short period of time, either the tester is not installed correctly or there are coolant leaks.
Check for coolant in the engine oil. If coolant is in the engine oil, the cylinder head gasket is damaged.
Check to see if coolant is getting into the transmission oil.
If coolant gets into the gearbox oil, the automatic transmission radiator is damaged.
