Leak Check

WARNING: This page is about a different car, the 2003 Infiniti M45. However, it is still accessible from the selected car via links, so may be relevant.
WARNING: Never remove the radiator cap when the engine is hot. Serious burns could occur from high pressure engine coolant escaping from the radiator.
CAUTION: Higher pressure than specified may cause radiator damage.

To check for leakage, apply pressure to the cooling system with a tester.
