Yeah you're right, the Haynes does say that the "thermostat rating" is 195 degrees. I must have missed that when I was skimming over the manual. I was really surprised that it wasn't listed in the Integra owners manual. Everything else seems to be in there, whether important or not. The Haynes doesn't state, but I think the 195 rating is the fully open temp. I'm not sure though. I'm gonna go over to the Honda dealership today and find out which temps they have in stock and which one they think is the right one. I think when I changed it about 3 years ago, the lady at another Honda dealership gave me the wrong one, or the incorrect info, on what the right temp would be for the car. I guess it's my fault for not double checking. The car has been running fine and has plenty of heat and no problems since the change. It just seemed to me that the car was running a little colder than it should.
