Hi Vikas, Yes I can feel hoses becoming soft to harder and yes dashboard guage is mirtoring the number I see on my scanner. Maybe you are right there is no way is going down in 5 second and I'm going to go ahead and replace the thermostat with the OEM from the Honda because I hate to crank up the car every time and see temperature gauge going up to 230F. I will try my best to take a picture from my iPhone. The problem has been taken care on FPR and engine is running better than before expect overheating issue.

If the thermostat stays stuck until it reached 230 and then suddenly open up, I could see temperature dropping very fast because now the cold water and the very hot water will mix. You can verify this theory by feeling the hoses and see when they transition from being soft cold to hard hot. That tells you that the thermostat has now opened up. Looks like you should just get a new OEM thermostat from the dealer if you are going to do the job again. Is dash board gauge mirroring the numbers you are seeing on the scanner? On the related topic, I need to know the steps involved in replacing the thermostat. If you don't mind, can you take some picture during the procedure? I am presuming you replaced the FPR regulator and that problem has been now taken care of?
