Installing the Oil Cooler

The optional Sonex / AeroVee Fence Baffle  kit includes laser-

cut parts for the oil cooler installation.
 1.  Position the oil cooler near the back of the lower shroud 

with the inlet ports facing forward.  Make sure the cooler 

does not interfere with the exhaust and mark the location 

of the mounting holes.

The oil cooler is mounted to the shroud. This photo shows the 

oil cooler hoses and baffle seal already installed on the cooler, 

however these steps come later.

 2.  Drill four 3/16" diameter mounting holes in the shroud to 

match those in the oil cooler and attach the cooler with 

four AN3-3A bolts, MS20365-1032 nuts, and AN960-10 

washers. 

 3.  Cut an air passage in the bottom of the shroud and install 

an air deflector to force the air traveling under the oil 

sump to exit through the oil cooler.

 4.  Attach the oil cooler shroud to the engine case with four 

M6x1 screws, or re-tap the holes and use 1/4-20 screws. 

See photo below.

Forward

This view, looking up at the bottom of the engine, shows the 

clearance hole for the oil temperature sender (see step 3).

Temp. 

Sender

 5.  Apply teflon paste (do not use teflon tape) to the threads 

of each AN912-4D bushing and install one in each port of 

the oil cooler.

 6.  Apply teflon paste (do not use teflon tape) to the threads 

of two AN816-6-6D nipples and install one in each of the 

bushings installed in step 5.

The oil cooler shroud is attached to the engine case at each 

corner of the case's oil sump.

Existing mounting 

hole in case.
