Heater hose bypass kit for Nissan RB Engines, to keep water flow from the rear of the engine once the heater system has been removed
The kit consists of 10AN hose & fittings, with our custom machined adaptor for the rear of the thermostat housing.
The thermostat housing fitting is available with and without a 1/4”NPT side port. Commonly used as a water return from turbo, throttle body, etc.
Please note - the kit is not compatible with factory Holden RB30 engine mounts due to clearance issues.
