Liquid cooling an aircraft engine is like air cooling a submarine
engine...

What has liquid cooled engines to do with intercoolers?
And if liquid cooled engines are so bad why did every airforce want
liquid cooled engines for their fighters in WW2 (except the USN)?
some may have not had them in enough numbers (Italy, Japan) but they
wanted them.

Liquid cooling lends itself to improved streamlining and improved
cooling distribution among the cylinders. Its main drawback is
vulnerability of the cooling system to debris and small arms fire.

Oil coolers are every bit as delicate as radiators (but smaller and
therefore harder to hit with a golden bb). A hit in an oil cooler would
bring down an aircraft just as quickly as a hit in a glycol radiator.

Air cooled engines (in aircraft, not submarines) are lighter and less
complex to operate than liquid cooled engines.
