TracTuff R40 Swirl Pot - V1


This swirl pot starts with a discontinued Gen 1 billet flange that has been modified and has a unique entry tube that covers the two original coolant passages. 

The outlet itself can be configured for standard hose (1.25" OD) or -16 male flare  and you can choose to have an accessory bung  and/ or heater outlet bung added to any open space on the tank.

The hardware kit includes three M8 stainless steel socket head bolts and a Genuine Honda gasket. The swirl pot is welded so that it sits level when bolted to an engine leaned back 15° (OEM position).

Space between the swirl pot and the flange make the two forward most mounting bolts a challenge to get to without the right tools. If you don't already own one, you may want to add a 6mm Stubby L-Key.

NOTE: Made to Order - Contact for ETA - If you are interested in a specific design that varies from this, please email us at The modification made to the flange meant the removal of the ECT and heater outlet ports. The ECT port is essential to the function of the ECU and has been added but the heater port is not and will be left as an option. 

The cap bung has a 1/16" NPT port for connection to an overflow and uses early model Honda radiator caps; such as an 88'-91' Civic/ CRX or 90'-93' Integra. If you are using AN lines, I recommend designing the upper radiator hose so that there is droop/ give... so the engines movement and does not push/ pull on the radiator and fatigue any parts.
