Hi All,

Thermostats always generate interesting discussions.

I use a 180-degree thermostat in my car. However, what's equally important
is how effectively the thermostat regulates the coolant temperature. A
thermostat that is fully closed or fully open is no longer actively
controlling the temperature. The normal operating range is typically the
opening temperature plus 20 degrees. For example, a 165-degree thermostat
should maintain the temperature between 165 and 185 degrees, while a
180-degree thermostat should keep it between 180 and 200 degrees.

If your current thermostat maintains the coolant temperature within its
specified range under normal driving conditions, then it's the correct one
for your needs.

Harold
