Pressure Test

WARNING: Never remove the radiator cap under any conditions while the engine is operating. Failure to follow these instructions could result in personal injury and/or damage to the cooling system or engine. To avoid having scalding hot coolant or steam blow out of the radiator, use extreme care when removing the radiator cap from a hot radiator. Wait until the engine has cooled, then wrap a thick cloth around the radiator cap and turn it slowly to the first stop. Step back while the pressure is released from the cooling system. When you are certain all the pressure has been released, press down on the radiator cap (with a cloth), turn and remove.

1. Remove the radiator cap. Fill the radiator as needed. Fit the pressure tester to radiator neck using an aftermarket adapter.
2. CAUTION: Do not pressurize the cooling system beyond 102 kPa (14.9 psi) .
3. 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 required.
