still replace the ECT, if that goes then the temp gauge goes mental, coolant error codes can come up and the engine will run like a bag, esp if it get to hot and the fans dont come on, could melt piston blow the head anything, not hard to replace, and i thought on the *v the ECT was under the water bottle but could be wrong, been a long time since i had my eyes on a 8v lump!

Lol. Ok well your sensor is on the top left corner at the front just follow the big coolant pipe up to the thermostat and you'll see it poking out the side with the wire running under your rocker cover along the side of the cam cover and back to the loom.

aint the sensor for the Z16XE on the thermo housing? built in as one unit same as the Let thermo, and best way to replace is buying a hole neww thermo? been a while since i worked on a Z16XE last time was my old hatch!

You are right the coolant sensor is stuck on the side of the thermostat but it is removable from the unit.

better practice to replace both parts, no point doing the sensor and then thermo goes 250 miles later
