WARNING: This page is about a different car, the 2018 Nissan Titan XD. However, it is still accessible from the selected car via links, so may be relevant.
Installation is in the reverse order of removal.
CAUTION:
Do not apply power to the coolant heater (1) until the cooling system is filled, and the engine has run long enough for the thermostat to open and allow the air to escape.
