If your rotary is over heating on take off and you need to get back
 on the ground right now consider using one of these small high
 pressure pumps to spray water on the rad.


 For the time to climb air plane I bought two. One for the rad spray
 bar and one for water injection into the intake manifold.

 Easier than just using one and a selector valve.

I wish I could use one of these for the rear engine oil cooler on my C337 for those hot days with long holds prior to takeoff!  A few times I have had to shut the rear engine down and taxi back to prevent temps redline.  I doubt my mechanic/IA would agree this would be a "minor modification/repair".

Take it off when you get an annual :-)

What a coincidence. Peter Garrison contacted me with his oil overheating
on his Melmouth Continental.

Make sure the oil cooler does not "see" an exhaust pipe.
