Pressure Test
Pressure TestWARNING: To avoid personal injury, do not unscrew the coolant pressure relief cap while the engine is operating or hot. The cooling system is under pressure; steam and hot liquid can come out forcefully when the cap is loosened slightly.
1. Remove the radiator cap. Fill the radiator as needed. Fit the pressure tester to the radiator neck using an aftermarket adapter.
2. CAUTION: Do not pressurize the cooling system beyond 102 kPa (14.9 psi).
Pump the cooling system to a maximum of 102 kPa (14.9 psi) and hold for two minutes. If the pressure drops within this time, inspect for leaks and repair as necessary.
