My 4310 would blow engine heat out around the hood and fuel door gaps and hit me in the face and on my legs. I decided to try to redirect it away from me and succeeded.
I cut some vents in the side panels and used a heat gun to bend them inwards. I also put some foam tape around the hood gaps and fuel cap ridges on the tank. This worked okay until I put the loader back on and I discovered the heat was now hitting the loader frame and still being directed at my legs so I cut some deflectors out of Coroplast sign material. I taped those to the new vent openings and to the loader frame to send the heat outwards. Life is much cooler now.
