The surge has happened several times while at idle and in gear slowing down to red lights i had to drop into Neutral to keep from running into ppl.
There is two coolant temt sensors.
The one in head is for dash light or dash gauge.

The two wire tempt sensor to pcm or code 15 is usually on upper front of engine.
