Take out thermostat, put it in a pot on stove and heat up. Get a thermometer or laser temp reader and watch wat temp it opens. U can even try running it without thermostat in summer and c wat happens

    It starts right back up but stalls at stops, what can cause this? I've replaced water pump, thermostat, heat sensor, fan clutch, radiator cap and even flushed the system. I'm lost.
