WARNING: This page is about a different car, the 2018 Nissan Titan XD and 2018 Nissan Titan. However, it is still accessible from the selected car via links, so may be relevant.
WARNING: Do not remove radiator cap when engine is hot. Serious burns could occur from high-pressure engine coolant escaping from water inlet. Wrap a thick cloth around the cap. Slowly turn it a quarter of a turn to release built-up pressure. Carefully remove radiator cap by turning it all the way. Note that the reservoir tank cap side is also under pressure.
NOTE: When removing components such as hoses, tube/lines, etc., cap or plug openings to prevent fluid from spilling.
