Kiawasaki FR651V oil cooler ?

[Tiger Small Engine]

Because these are air cooled engines, making sure the cylinder heads and cooling fins are free of dirt, grass, and debris is also important. Oil coolers help no doubt, however, do not neglect checking and cleaning engine under the shroud and tins as necessary.

I suggest, if you haven't already, Google "purpose/benefits of oil cooler on small air cooled engine."

All of this is from Google using YOUR search words. As we will see, I captured every paragraph link and posted here for all to see. Notice the SOURCES on the right side of the screen grabs. None are credible.

You can put three coolers on if you wish. Use Rolls Royce aviation turbine oil if you like. Just don't see much of a benefit, from my poor eyes. Just a mower engine.
