My old Monkey Wards 2 piston, single stage, 6 gallon (guessing), 1 hp,

of compressor?

It is basically the same thing as a car engine without the fuel to
burn to make it hotter. Car engines need cooling because of the added
heat from the fuel being burned. They cool car engines down to 180-
200 degrees, which is the normal temp. I am just guessing, but I would
think 180 is about right.

It's not the same or similar to a car engine. In a car engine
without fuel, the air would be compressed on the compression stoke,
then immediately decompressed on the power stroke in the cylinder.
When you compress it, it gets hot. When you decompress it, it gets
cold. In an air compressor, the cylinders are strictly
COMPRESSING. The decompression takes place elsewhere, eg where it's
being used in a tool, or blowout gun, etc.
