Seaplane Oil Cooler
A few years ago, a forum post included an attachment that was a picture of the seaplane oil cooler installation on an early O-300 equipped Cessna 172. Does anyone have that picture? For that matter, does anyone have any pictures (and/or parts) for the seaplane oil cooler installation?

Re: Seaplane Oil Cooler
The early 172 (which has the O-300 installation similar to the 170-B) has the following illustration and parts listing for the seaplane in its IPC:

Re: Seaplane Oil Cooler
Thanks, but I already have the IPC page. What I really want is a picture of the oil cooler installation on the front of the engine. Maybe a better part number than the Cessna 0550219-19 part number for the cooler. I'll bet the cooler was made by Harrison, since they made a cooler for the O-300. The cooler is unusual though, since the inlet and outlet are on the sides, not the top.

Re: Seaplane Oil Cooler
Unfortunately insufficient illustration is evident. There may be fittings associated with the cooler (hidden by the baffling) which mate-up to the ones shown in the IPC. The IPC may only catalog user-serviceable parts provided by Cessna…not parts associated with the cooler assy. Without addt’l info from Cessna regarding the conversion kit for floatplanes it’s difficult to know.
