There are actually quite a few threads on this subject across most(if not all models). The general consensus is to not use a full windshield, use the Wolfsnout insulation behind your back and insulate the tunnel. It's a combination of direct engine heat on your back and heat from the radiator lines in the tunnel.

 

I feel like it comes from the floor the most. Does it come mainly from there or behind me like you said? Are you saying to insulate just behind the seats or on the outside of the cab closer to the motor? And yes I do run the full windshield. Just what it came with. I do have a half windshield but the wind hits me right in the face

 

The Wolfsnout kit goes on the inside of the rear firewall behind the seats. It's actually pretty effective for that part. I doubt that you are actually getting heat from the "floor" since there's really nothing under there to cause it. The tunnel gets pretty dang warm as you'll note if you put a drink in the cupholders. The hot air stays down there, especially with full windshield and doors.

 

Ya we had some metal drink cups down there this weekend and the gf commented that it was very very warm. I’ll try looking up the insulation kit

 

I've found that stuffing an old towel or blanket between the seats makes a noticeable improvement. That's a quick easy and free fix that can easily be reversed in the winter. Also make sure those rubber boots around the seat belts are in position. Since I mostly ride in the mountains in Colorado where it's not that hot, I haven't needed to do anything more. Anywhere else in the country and I would probably look at getting the Wolfsnout UTV Cooler cab kit.

 

Looks like the kit is a bit spendy. May have to give the towels a shot first. I put harnesses in and had to cut the rubber boots where the belts go through but I wouldn’t think that would give off that much heat just from those. But it is def warm inside.

 

I installed the Wolfsnout Insulation Kit. Worked great and wasn’t bad to install at all.

 

My turbo model was blowing extra heat in when the fan would come on. I used foam tape around all the edges and mating joints of the firewall and around the brake master cylinder. Also took the hood off and made some seals everywhere air was flowing up into the dash. Finally I insulated the tunnel with some "double bubble" and behind the rear seats. It felt like someone blowing a hair drier on our legs first ride. Now is much better. I could tell last ride that some hot air was coming in, and found some foam tape pulled loose on the edge from trailering or water splash.

 

You can spend almost and in some insistence's more and not get as precise fitment or as good of permanence than our kit. You can get the front only, which addresses many areas on a budget. Very effective on its own. The back is a three layer insulating sound controlling dust sealing mat that goes from the top of the seats to the front bottom of the seats . Made from FATMAT back, a mylar bubble core, seamed to a rubber seal. Reduces heat, engine noise and dust. It is all removable as needed.

We also now have a tunnel kit for the XP PRO per many requests.

I got tired of the blast furnace, and installed the Wolfsnout complete kit. Made a huge difference.
And when it gets cold again, I can yank it out until summer.
