Specs At A Glance

Good To Know

Q: What are the signs that a radiator shutter assembly needs replacement? A: Common symptoms include a check engine light, active grille shutter fault codes, or the engine taking an unusually long time to reach operating temperature.

Q: Does this component affect vehicle aerodynamics? A: Yes, by closing the shutters when cooling demand is low, the vehicle reduces the amount of air entering the engine bay, which significantly lowers wind resistance at high speeds.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
