How can you tell if it is a bad thermostat or a head gasket?

Check for water in your oil, if so, this is a sign of bad head gasket. White smoke from the exhaust and loss of coolant with no apparent leak are all signs of a blown head gasket. You can also remove the thermostat (it is much cheaper to replace and easier to troubleshoot as well). If the temperature of the vehicle lowers, your thermostat was the problem.
