Get some actual temp of coolant. I had some horrible engine performance problems when my thermostat soft failed. I only knew it failed when the ambient temp dropped low enough the heater no longer warmed the cabin. Turned out my thermometer effectively opened at 65C vs 90C and because of the utterly moronic non gauge that looks like a gauge but functions like an idiot light (by snapping to 12 o'clock position between 60 and 110°C) it's worse than useless for determining anything useful. Use hidden odometer functions to read engine temp and if possible oil or transmission temp
