But there is a radiator at the front of most air-cooled Porsches; although it cools oil instead of water.

In 1969 on the 911S, a front mounted radiator-style cooler
was mounted as standard equipment in the front right fender
well. In 1973, the newer trombone, serpentine, loop or
cooling pipe cooler as it was called, replaced the radiator
style cooler. This style of oil cooler was used through 1983.
And now that I check wikipedia, I learn that the Beetle also had an oil cooler! My god, I've been living a lie.
The 911 has two oil coolers (well, from the mid '70s, anyway) - one in the right front fender, and one mounted to the engine itself.
Many water-cooled cars do have an oil cooler, but it's not the primary means of cooling the engine. In those cases it's more about keeping the oil at a constant temperature.
Oil cooled cars have sump capacities 2x water cooled cars.
