Genuine Toyota Cylinder Head Tube to suit all variations of the 2H / 12HT engine.
These tubes allow the Cylinder Head bolts to pass through the Head, while blocking off the water passage / gallery from leaking into the Cylinder Head Bolts and in some extreme cases leaking out of the head.
After a recent experience, these are something i feel everyone should replace when having a 2H / 12HT head serviced.
