The Nightrun Garage 2jzgte water neck gasket kit includes both coolant pipe O-rings and the coolant water neck gasket. The O-rings go on the coolant pipe that connects the water neck to the water pump housing and the coolant water neck gasket connects the coolant water neck to the cylinder head. Both O-rings and gasket should be replaced whenever the upper water neck is removed. This Toyota OEM kit includes the (2) O-rings and (1) gasket. This kit works with 1jzgte and 2jzgte engines but does NOT fit the 2jzge.
