Engine coolant temperature sensor in a one piece design. This sensor will fit Datsun 240Z, 260Z, 280Z and 280ZX, 1970-83 and Datsun 510 68-73. This coolant sensor sends the signal to the temperature gauge and installs in the thermostat housing. The original sensors are a 2-piece style and this replacement is all one piece.
*Not for digital dash on 280ZX.
*This sensor includes an O-ring, but does not seal up on the O-ring, it seals like the original sensor on the tapered portion of the sensor.
