Evans Coolant Temps
As 512 says, at 7.5% over you should be fine with that.
IMO, the 4 small cores won’t flow enough to keep up with what you have. Two 1.00 or 1.25 cores will out flow your radiator all day long and twice on Sunday.
I agree in not using a thermostat IF you can A) get some temp in the engine so you can have a heater (unless that doesn’t matter to you) and B) you can control engine temp across all the possible climes you drive in.
Where I’m at, it gets down to single digits in the winter but there isn’t a cloud in the sky and the road are dry. So I drive in that weather. Without a thermostat in that temp, I doubt I could get 100 degrees of engine temp. In the summer it hits the 100’s for a quite a bit. Even then, I never hit 180.
I’d look at the radiator.
