MaineFusion Report post Posted January 10, 2014 One thing that probably helps on really cold days is to recycle cabin air so that the heat system doesn't have to bring super cold air up to temp to heat the cabin. I tried recycling air today and it did seem to help both cabin heating up and keeping the engine warm as the heat system wasn't drawing off so much heat. 3 hybridbear, ptjones and B25Nut reacted to this Quote Share this post Link to post Share on other sites
