Another question regarding winter operations... how do you block off part of the oil cooler and what oil temp do you try to achieve?

It is easy to make an aluminum cover plate to block 1/2 of the cooler area, and secure it with the two mounting bolts. Watch your temps on climbout on warmer days, and if necessary climb at shallower angle and/or reduced power to keep the oil temp out of the red.

The much better solition, is to install an oil thermostat, such as the one offerred by Aircraft Specialties. Then you needn't worry about oil temps, and your warmup to 122F will be way shorter. Lots of previous threads on this.

As advertised, the Thermostasis oil therm will pay for itself with gas savings. Even in warmer weather, it warms up faster. No sitting and burning gas while waiting to warm up. You don't have to do anything. Whether winter or summer, it warms up faster. The type auto stores sell ( designed for trans cooling ) do not work as well.

Default Radiator Blocking

I made an aluminum cover to fit over the entire oil cooler. The aluminum plate is riveted to a piano hinge and connected to a cable so I can open it or close it in flight.
I'm thinking on making the same thing for the incoming cooling air for the engine because when it is below zero Fahrenheit the engine only gets up to about 125 degrees.

Default Oil shutter

Have you seen this one?

It works perfect in our RV9. With the handle inside your cockpit you are in the position to manage your oiltemp precisely.

That's looks like a real good solution. I need to know if it will fit on the RV-12 oil cooler. Does it close off completely? Looks like it remains partially open probably for safety.

It is, indeed. It closes off 100%, if you want. Check it out with Van's !

I may actually do this sooner than later. I flew the RV-12 today with 36F OAT and oil is just shy of 160F with engine at sustained 5100rpm.

I installed mine when I lived in PA and now live in Maine and fly well below zero most of the winter. I can keep my temps up to 220.





Slight mod to make it larger to fit over the oil cooler.




Fully adjustable in the cabin in flight
