The rotors in a rotary engine are cooled by oil sprayed into them from the eccentric shaft. They hold a considerable amount of oil that is continually being pumped in and over flowed out. The factory oil coolers are the best we have ever found for cooling capacity. Virtually all of the aftermarket ones are not even remotely usable. Do not run your engine for anything more than about 15 minutes with out an oil cooler.
