Overcooling problem.

[LowR3V'in]

Hello.
I seem to be having an overcooling problem
while at freeway speeds. I'm wondering if this
seems normal? I see temps as low as 160 cruising.

If I stay at low speeds it'll reach normal operating temps 195-200.
It also takes a good while longer to get to temps compared to the
old m20.

Running no fan btw.

Could be the thermostat, but could be normal?
I know with the m20 it would reach 190 pretty quick and would
never go under 189.

All opinions welcomed.


One more thing. When it overheats goes to 210 (from a stop) I just drive for maybe
1 minute and I see it go down to 195!

Thermostat stuck open occasionally, or it doesn't close when the temperature goes down ?
