You can check the thermostat by removing it, placing it in a container of
water and heating the container - use a thermometer to verify the
temperature the thermostat opens.
You can also measure the coolant temperature to see if the gauge is reading
correctly.
The fact some coolant spits out may indicate that you have overfilled the
radiator. Water expands as it is warmed so if you fill the radiator to
capacity when its cold, it will be too full. Check the level when its warm
and fill close to but not full. If its cold when you check the level, be
sure to keep it a half inch to maybe an inch below capacity.
