Checking Cooling System For Coolant Leaks
WARNING: This page is about a different car, the 2007 Nissan Pathfinder. However, it is still accessible from the selected car via links, so may be relevant.
To check for leakage, apply pressure to the cooling system using Tool.
Tool number : EG17650301 (J-33984-A)
Testing pressure : 137 kPa (1.4 kg/cm 2 , 20 psi)
WARNING:
Never remove the radiator/reservoir cap when the engine is hot. Serious burns could occur from high pressure coolant escaping from the radiator.
CAUTION:
Higher pressure than specified may cause radiator damage.
