Using special tool, check radiator cap for its relief valve opening pressure (108 kPa (1.1 kg/cm² , 15.6 psi)).
Inspect the cooling system performing the following steps.
1. Fill the coolant and attach special tool to radiator filler.
2. Pump it up to 108 kPa (1.1 kg/cm² , 15.6 psi) and check that the pressure does not drop. If the pressure drops, inspect all hoses, the radiator and the water pump for leaks.
