Leak Check

WARNING: This page is about a different car, the 2005 Infiniti FX35. However, it is still accessible from the selected car via links, so may be relevant.

To check for leaks, apply pressure to the cooling system with the radiator cap tester (commercial service tool) and radiator cap tester adapter (SST).

WARNING: Do not remove radiator cap when engine is hot. Serious burns could occur from high-pressure engine coolant escaping from radiator.

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

NOTE: In a case that engine coolant decreases, replenish radiator with engine coolant.
If anything is found, repair or replace damaged parts.
