Cooling issue, but this time it's to cold...

I will say this about Sunpro gauges, they are junk from what I can tell, at least the cheap ones I bought to use temporarily. The temp gauge still never reads over 120 running and 150 after it's turned off. But the thermostat is operating correctly. The oil pressure gauge has tested low in readings too, so I would not trust Sunpro ever again.
