Fill through the pin hole. Try 15 mL or so, and test to see if the
fan pulls. If not, add more in fairly small increments (5mL or so)
until it works well.
Make sure the pin moves, of course.
Problem is that the original fluid leaked out. Adding more will not
fix the leak.

I am attempting to "repair" my OM603 fan coupler - it unit does not appear
to have more resistance when hot ( 90deg + ) hot or with control pin (
under the bi-mettalic strip ) removed. How does one inject for silicone
fluid into the unit and how does one know when its enough?
