98 Grizzly 600 Oil Cooler

I’m looking to put a much bigger oil cooler and fan in my 600 Grizzly, as the factory one just seems to be way to small and am not doing that whole relocation to the front rack setup, as I don’t go heavily into deep mud and use my quad for alot of different things and need the front rack space. I have a few questions I am looking to try to find answers on. Has anyone ever done this and have pictures and info on what they are using and how the mounted it? And which line is the intake and which line is the return on the factory cooler (standing in front looking at the quad)? The attached link is one I found on amazon and if it will fit in the space I would like to use it. I’m waiting for a response on what the dimensions are as they aren’t correct on the description.
