Narrative:

I took off from teb on trip to east hampton, ny. Approximately 15 mins after takeoff while I was cruising at 2500 ft front engine (cessna 337) started to show signs of overheating (cylinder head and oil temperature gauges). Front engine cowl/flaps malfunctioned and would not open. Cylinder head temperature started approaching red line and I shut down front engine to prevent seizing up and possible fire. I contacted new york approach and advised I would be landing at frg. I also clearly advised that this was not an emergency. I was cleared direct to frg and landed without incident. Fire truck followed my aircraft after landing and when I stopped at ramp, the driver of fire truck asked for certain information which I gave him. He asked for license and medical certificate. I checked my pocket and not finding it I advised him I did not have it. A short time later, after he drove away I discovered my license and medical certificate was in my flight bag in the aircraft. I took off cowling of aircraft and after some time the front cowl/flaps operated normally. I checked with my mechanic who is very familiar with aircraft and he advised me ok to fly aircraft provided on extended runup that all instrument gauges operated properly. After extended runups and high speed taxi, I flew aircraft back to teb where I had mechanic check aircraft.
