That is the location for the 2-valve engines. I've attached the procedure from the FSM for the 4V engine.

Should be there in the cylinder head, front driver's side, under the intake manifold. But you wouldn't need to remove the intake to swap it out. Just remove the alternator and you have access to it. It's a dry sensor, no coolant touches it. Does your temp gauge work in the instrument cluster ?

The '04 Expy still has the 2V motor.
