Coolant Bottle Cap (11-21 3.6L, 5.7L HEMI)

Exceptional Coolant Bottle Cap Replacement. Keep your cooling system’s functionality with this Coolant Bottle Cap. This coolant cap features an OE-grade design and rigid build quality to provide excellent sealing of your coolant bottle. This in turn maintains correct internal pressure to ensure your coolant bottle functions properly. This factor is particularly important as a malfunctioning engine cooling system can lead to damage to your engine block.

Rigid Build Quality. This coolant cap features a rigid automotive-grade plastic construction, making this component extremely resistant to engine bay heat damage. Moreover, this cap is precision-molded following OE specifications for superior a fit and finish. Meanwhile, a high-grade alloy collar is a machine formed and pressed onto the cap to provide a tight seal when installed. Lastly, this bottle cap comes in a standard black color.

Uncomplicated Install Procedure. This coolant cap installs onto your Challenger’s factory coolant bottle without the need for modifications. Additionally, installation won’t require any tools for convenience.

Application. This Coolant Bottle Cap fits all 2011-2021 3.6L and 5.7L HEMI Challenger models.
