I am looking for some feedback on what, if any external oil coolers are available for the Teryx. I am looking into getting my 840 kit but before I do, I would like to know if anyone is using an external oil cooler. If so, where did you get it? How much was it? How much cooler is the engine temp? I believe the Rhino's come with one stock, so I'm looking for info if anything is available. I would like to keep using my stock radiator set up if possible. Any info would help. thanks.
