Water Temp... 1HZ

[Gun Runner 5]

Can anyone tell me where the water temp. sending unit is located on my 1HZ? (1990 HZJ77)
Thanks

if its the same as the 1HD then it should be in the vicinity of the thermostat, I think. There is something in the block aft of the injection pump also if I remember.

It doesn't seem to be where one would expect it to be.

Should be up on your upper rad hose inlet

It's not.
It's not in any of the places where it would commonly be expected.
