So you see a bunch of 300 guys running oil coolers on their front racks and got me wondering. What the difference between using one of those and a radiator relocator. Like I know they keep something cool but what for? Also how does a 300 keep cool by itself without either one since their so old and didn't come with one stock? Me personally, I just ride in water to keep cool lol.

For the 300’s intended use it never needed an oil cooler, they run great without them. The fins built into the cylinder head are it’s stock means of cooling, just like the old school dirt bikes, KX500’s etc etc.
Usually people fit them for specific reasons, hauling heavy loads at low speeds and high revs, working in hot states, Arizona for example. Mud riding is a very popular reason for fittinga cooler, high revs for a prolonged period of time whilst not getting anywhere quickly.
Mounting them higher up on the front carrier is so that the cooler catches as much air as possible as often as possible, if it’s under water or in mud it won’t cool as well as it should.
It is possible to fit them underneath where the cooling fan fits, if you don’t have a cooling fan that is.
