I bought these shutters from HighwingLLC and they also help to control the temp. Control of the shutters is done by the two knobs on the instrument panel.

Re: 912 Winter Operation
Well today I had a chance to try out my new "sliding shutters" as suggested by Chuck (cap01). I installed mine on the rad though, and still use tape on the oil cooler because it is so easy to get at. It was -7 degrees C with a fairly low ceiling so I just stayed in the circuit.
With the slider fully closed ( I adjusted it to always leave small openings)the water temps stayed steady at 180F and oil at 200F. Even throttling back for landing the temps maintained constant. With these results I should be able to leave this assembly in place til the hot summer (plus 30C) July temps. All in all I believe this to be a success. The next time I have the cowl off I could post a pic if anyone is interested.

Hi, Don glad to hear your shutter worked . I didn't really have a bunch of temp problems in the circuit, my cool temps happen in about 30 minutes of cruising, -15 C at 52-5300 rpm . having the rads closed off has got to make a difference! Kevin

My plan is to use the following shutter, quick, easy simple to install. I don't have to design it!

Hi Paul
I don`t have enough clearance between the oil cooler and the cowling or the prop on my smooth cowl Vixen to use that type of shutter. I suppose with some serious modification it would work but I find the tape on the oil cooler is fine. I was going to install it on the rad, but Chuck`s idea seems to work well.
Good luck
Don
