I clamped the cooler to the face of the cowl
duct and match drilled the top holes. I
installed the bolts to hole the cooler in place on the duct.
Using the guide cones I match drilled the
lower holes and installed the fasteners.
I then clecoed the duct to the lower cowling. I reinstalled the lower cowling and found the
oil cooler to be about ½” from the muffler.
Because of all of the discussion on the VAF RV-12 form I am concerned
that I need to do some kind of modification to the cowl duct to increase the
distance. Before I go any further I am
going to research the best approach to take to increase the coiler to muffler
distance to at least 1”.
