This RAD Industries adapter was designed for the 2JZ-GE head so you can adapt the exhaust side coolant port to AN fittings for ease of plumbing on your build. This billet coolant adapter bolts directly to the head using an o-ring to seal to the mating surface on the head. It has -8 ORB threads so you can install an AN union and adapt to the size of the plumbing you want to use on your build.
This is a multi purpose part and also bolts directly to the back of the GTE and GE water pump in place of the coolant hard line that runs to the back of the block. You can use this billet coolant adapter to convert the hard line to an AN fitting on your build.
2JZ-GE Use:
- Coolant exit port on exhaust side of head
OR
- Back of water pump
2JZ-GTE Use:
- Back of water pump
Works in combination with RAD Industries 2JZ-GE Upper Water Neck
