Yamaha Rhino 660 Pro-Cool Rhino Radiator
We experimented with the available solutions from other aftermarket companies and did not achieve the desired results. When running under a heavy load, we still experienced overheating problems. After more research, we found the cause to be that a high performance built Rhino motor will typically spin 2-3k rpm higher than stock. What this does is move the water through the radiator so fast, it does not have time to cool.The stock design is only about 70% efficient due the inlet/outlet location. In testing, we found the water coming out was only slightly cooler then the water going in.
