So it
is a Delta. Cool - I'm impressed on your selection! (That's no
cumputr prepalur fan)

Nice touch with the thermal switch to activate the fan at 200°F. If you were to, say, simply Tee off the right side air tube and port, then it would be cooling the oil on warm-up. Now *that* wouldn't be a very good
engineering solution. (I hate that sluggish feel when the oil is cold.)
Very good work!
. . .There I go again,
just always praising anything to do with the coolcollar. .
