When I bought my 2013 Polaris RZR, it was running extremely hot (230ish) with several mods (snorkels, hp rad, etc). Nobody seemed to be able to track down the problem, so I went completely thru the cooling system myself and determined the high perf. rad that was on the machine wasn't cooling the fluid enough. Enter this used OEM radiator, and the problem was fixed. Machine now running cool as intended and I'm a happy customer!
