Leak Check

WARNING: This page is about a different car, the 2002 Nissan Sentra. 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 coolant escaping from the radiator.

CAUTION: Higher testing pressure than specified may cause radiator damage.

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