Most likely the new thermostat is the wrong heat range. It should be a 195°F thermostat. From a cold start up the engine must reach operating temperature within 10 minutes. Operating temperature is 195°F. If the engine doesn't, the trouble code will keep setting and the check engine light will keep coming on. Hope that helps! Jim
