Temp Too Low???

Ok, so your motor looks almost identical to my Wifes motor with the small hole and sender right where the green circle is.
This would be where the idiot light sender is.
If you want to keep the intake and don't want to drill and tap it. then they make a spacer that goes between the thermostat and thermostat housing about an inch thick and has holes for temp senders already in it.
