t-stat is brand new, was replaced on 10-11-18.. it was a 165° I replaced with a 195° because I thought that was the issue. it's not, it is the cold airflow over the motor.

I leave for work at 4am, this morning it was in the high 40°, above 65° outside temps I don't see the issue for the most part water temp gets to about 180°, but in the 40°-60° range water never gets above 160°ish. Head temps are even lower, I have temp gauge on both the water pump and the heads. as I had a ongoing overheat issue for several months. I have fixed that issue and the car now operates perfectly as long as the outside temps are above 65°.


Now with colder temps I have an under heat issue.


As I stated, I blocked off the side vents and upper grille area with some clear vinyl I had, same stuff used as "clear bra" on modern cars, doing so allowed less air flow and the water temp got to normal operating temps.
