Q: What is a radiator filler?

A radiator filler closes gaps around the radiator and support so incoming air is guided through the radiator instead of spilling around it.

Q: What problems does a worn radiator filler cause?

Open gaps can reduce airflow control, invite road debris into the core support area, and contribute to an unfinished look behind the grille.

Q: Are there other names for a radiator filler?

You may see this part listed under airflow and core support sealing terms.

Radiator filler seal
Radiator baffle filler
Core support filler
Radiator air seal
Cooling air guide seal

Names vary by manufacturer and OEM terminology.

Q: Does replacing it help cooling?

It can, by helping ensure more air is forced through the radiator rather than taking the easy path around it.

Q: Any install tips or cautions?

Dry-fit the pieces before final fastening and confirm the correct application, since radiator supports and front-end configurations vary.
