1jz/2jz Cooling system upper water neck and billet thermostat delete:
This kit is designed to work with the OEM water pump and deletes the factory thermostat housing with a billet plate. This design raises the fill point for easy bleeding, allows for sensor provisions (optional), and is aesthetically pleasing!
The upper water neck tank is built to order, giving you options for a 1.38” slip fitting (standard 1jz/2jz coolant hose), -16AN, or -20AN fittings. In addition, we can add 1/8npt fittings for temp sensor provisions.
If you are unsure about your needs, give us a call!
