Radiator Closure for Dodge Durango / Jeep Grand Cherokee 2015–2025 – Aftermarket

Radiator Closure / Air Deflector Panel

The Radiator Closure Panel (also frequently referred to as the Air Deflector Panel or Upper Radiator Cover) is the crucial plastic panel that mounts directly over the radiator support area. Far from being a purely cosmetic cover, its primary function is to strictly channel and optimize incoming airflow straight through the radiator and A/C condenser. By preventing air from escaping over the top of the core support, it guarantees maximum engine cooling efficiency. This premium aftermarket replacement is molded from highly durable automotive plastic built to survive extreme engine bay heat, restoring front-end sealing integrity and keeping dust or debris away from vital cooling components.

Technical Specifications

Technical Note: This panel is often overlooked or left uninstalled after front-end body repairs or routine engine service. If this deflector is broken, cracked, or completely missing, you may experience subtle engine temperature spikes during hot summer months or while idling in heavy traffic. This happens because high-velocity air escapes through the open gaps instead of forcing its way through the radiator fins.

Pro Tip: Make sure to have a complete set of matching plastic push pins/fasteners ready during installation to ensure the panel sits tight and remains 100% vibration-free at high highway speeds.
