WARNING: This page is about a different car, the 2006 Nissan Titan. However, it is still accessible from the selected car via links, so may be relevant.

WARNING: Never remove the radiator or reservoir cap when the engine is hot. Serious burns could occur from high-pressure engine coolant escaping from the radiator or reservoir.

To check for leakage, apply pressure to the cooling system at the reservoir filler neck using suitable tool and Tool.

Tool number: EG17650301 (J-33984-A)

Leakage test pressure: 137 kPa (1.4 kg/cm, 20 psi)

CAUTION: Higher pressure than specified may cause radiator damage.

NOTE: In case that engine coolant decreases, replenish cooling system with engine coolant.
If any concerns are found, repair or replace damaged parts.
