Radiator Shutter Lower for 2019-2021 Nissan Altima (All Trims) - OE 623306CA0A

A Radiator Shutter for the 2019-2021 Nissan Altima

This is a lower active grille radiator shutter built for the 2019-2021 Nissan Altima across its full trim lineup, cross-referenced to OE number 623306CA0A and Partslink number NI1206106. If your Altima's check engine light references grille shutter position, or you notice unusual airflow or cooling behavior at the front of the engine bay, a malfunctioning radiator shutter is a common and often overlooked cause.

Why One Shutter Fits Every Altima Trim for These Years

The 2019-2021 Altima was offered across a wide range of trims, including the S, SL, SR, SV, SE, Sense, and Platinum, paired with either a naturally aspirated 2.5L engine or a turbocharged 2.0L engine, yet all of these variants share the same front-end grille shutter housing and mounting design. Because the shutter's function is tied to the shared front bumper and cooling system architecture rather than to a specific trim's badging or engine choice, the same part fits the entire Altima trim lineup for these model years. That means shoppers don't need to hunt for a trim-specific listing or worry that their SR or Platinum trim requires a different part number than a base S trim.

Compatibility

Fits the 2019-2021 Nissan Altima across all trims, including S, SL, SR, SV, SE, Sense, and Platinum, with either the 2.5L naturally aspirated or 2.0L turbocharged engine. Because active grille shutters are a fairly recent addition to many vehicles and can vary between model years even on the same nameplate, it's worth confirming your Altima's exact model year against the OE number above before ordering.

Signs Your Radiator Shutter Needs Replacing

A malfunctioning active grille shutter typically triggers a check engine light related to shutter position or performance, and can also contribute to reduced fuel economy since the shutters help manage aerodynamics when the engine doesn't need maximum airflow. Because the shutter also plays a role in engine cooling by regulating airflow to the radiator, a shutter stuck in the wrong position can occasionally contribute to overheating concerns as well. Catching and addressing the issue early helps avoid a more serious cooling system repair down the road.

Why This Component Matters More on Modern Vehicles

Active grille shutters are a relatively recent addition to mainstream vehicles, added specifically to improve aerodynamics and fuel efficiency by closing off airflow to the grille when the engine doesn't need extra cooling. Because this component actively moves and is exposed to the elements at the front of the vehicle, it's more prone to mechanical wear and road debris damage than the static grille panels used on older vehicle designs.

Installation Notes

Replacing this shutter means removing the front bumper cover or accessing it through the underside of the front bumper depending on your specific model's design, disconnecting the shutter's electrical connector, and installing the new unit in reverse order. Because the shutter includes an electrical connection to the vehicle's engine control module, confirming that connection is fully seated before reassembling the bumper will help avoid a repeat trip to the shop for a persistent warning light.
