When I purchased my (already built) Legacy it had no oil cooler door. In flight I could never get the oil temperature above 175 dF. Installed oil cooler door and control line in cabin. Now I can manage oil temperature and keep it in its happy place.

Subject: [LML] Oil Cooler Door Control on IO-550N Engine in Legacy?
Hey LML gang,
Working on our IO-550N engine installation… Already have baffling done and flapper door in front of oil cooler. We’ve heard mixed reports of whether it is needed or not. We need to decide if we really need to have cockpit control of the door or not. We’ve heard some people just remove the door or wire it open or closed depending on the season.
Would appreciate hearing about your flight experience with the Legacy with an IO-550N engine and the usefulness or not of control of the oil cooler door…
Thanks!
