Frequently Asked Questions
Is the supercharger coolant system separate from the main engine cooling circuit?
Yes. On Hellcat applications the supercharger has its own dedicated intercooler coolant circuit with a separate reservoir from the main engine radiator, and the Billet Technology 300111 fits that supercharger reservoir specifically.
Does the Billet Technology 300111 maintain OEM sealing?
Yes. The 300111 is designed to match OEM thread engagement and sealing, so it maintains the same sealing characteristics as the factory plastic cap.
Can I install this cap myself?
Yes. The installs directly onto the OEM supercharger coolant reservoir neck by hand, no tools or sealant required.
Installation Instructions
- Allow the supercharger cooling system to cool before beginning.
- Locate the supercharger coolant reservoir under the hood.
- Remove the factory plastic cap by turning counterclockwise.
- Place the Billet Technology 300111 onto the reservoir neck until snug.
- Verify the cap is fully seated and level.
- Check supercharger coolant level through the reservoir sidewall before starting the engine.
