Well, I am experiencing my first cold weather flying with my new bird. And, as I had expected I am seeing oil temps that are too cool.

What other "winterization" steps should be taken to fly safely in the winter with our LNC2s?

Thanks!

Dan,

I have a 2+3/4" scat tube that picks up from behind the #3 cylinder. I also have a butterfly valve at the firewall with a lever into the cockpit.

The lever in the cockpit is just left of the air filter lever in photo 6 on my web page. (http://www.dynacomm.ws/~lorn/) On my web page the Oil cooler butterfly must not have been installed because the lever was not installed when the picture was taken. I assume that my airplane builder had the same problem that you are having.

In the winter, I take off and fly with the butterfly closed. I open it when the oil temperature gets to between 170°F and 180°F, if I remember. If I forget to open it, the temp may get up to as high as 210°F. I don't think that is high enough to hurt the engine. The valve allows me change my oil temperatures by 20°F to 30°F.

I am very happy to have this butterfly, valve combination. I always hated the thought of having to install and remove a winterization kit. I may leave Detroit at 20°F and land in Jacksonville at 70°F. Then what do I do about the kit? Again, I sure like my oil cooler valve.
