I mounted a Vintage Air compact heater with defrost. Now I need to run the coolant lines and tie them into the system. Sidebyside Stuff sells a Heatercraft setup put together by Wide Open CO that has a Thermostat bypass: Heater Craft - Large Thermostat Adaptor Kit And they tie in there. Does anyone know which one that is? Heater craft sells them separately but there are two sizes and Arctic cat is not even listed.
Country Cat sells something but they don't seem to know what it is. HOSE,COOLANT-BYPASS-THERMOSTAT/ENGINE I emailed them and they are not to informed on what it even is.
Moto Alliance sells one but not listed for the Wildcat either: https://motoalliance.com/Site.Store.go?action=gotoProductDetails&id=1632
I like the idea of using the bypass so that you always get heat from the engine no matter what position the thermostat is in.

I also need to find a Y to tie in the return. I think its 3/4" x 3/4" x 5/8" I haven't cut into the stock line yet. Went to Napa they had nothing. I also want to put two valves inline besides the electronic solenoid just in case the core fails. Any suggestions on where to find a Y and shutoff valves. My heater line is 5/8"

The heater mounted up under the glove box. I just fabbed up a custom bracket. Tight fit to clear the coolant lines where they enter into the tunnel past the frame but it fits and should put out plenty of heat. It leaves plenty of leg room and this heater has nice 1/4" by 5" vents I mounted at the base of the windshield. One on the passenger and one on the drivers side.

They proper y fittings are a little hard to track down. I did some digging before and did find a place to order the proper ones but cant remember where the hell it was now. I wouldnt bother with a thermostat bypass, these rigs run hot enough that the t-stat isnt closed for long once you start it up. I did around and see if i can find that y fitting again.

Thanks for the information. I also found some parts. I bought a couple shutoffs from Amazon along with a couple Y's. Hope they work.
Wide Open Co does sell the Thermostat bypass separately for $80. Still contemplating that.

I will try and take some pictures this weekend. I already have heated seats and they do help allot. But since I am putting tracks on it for the winter the wife wanted to be a little warmer.
Soft doors this year. Maybe a Defender Cab next year.

Id love to have tracks and a full cab on the trail but by the time i add that up its about the price of another new Trail. I think my heated seats will do me. I didnt find it bad last year with the front and rear windshields and no seat heaters plus the misses doesnt do winter so cant see her sitting in there until the sun shines again. I saw a heated steering wheel too but for 500 bucks ill pass and just wear good gloves.

Got the heater mounted with the switches. 3 speed blower. Defrost, floor, or both. See attached pics.
I was going to for go the thermostat bypass but after looking at where the Y would be located I decided I will order and install the bypass.

Are there any propane heaters available? Some semi-open European offroad vehicles had a gasoline heater. (Hafflinger)

Heater is done. Works ok. I think I need to insulate the lines that run through the tunnel. The heat is getting sucked out of them. Around 20' of line. I was worried about the engine not putting out enough heat. I went for a short ride today to test out the new tracks, and watched the gauge. It ran around 170 to 185. So it seems good. The wife didn't complain about being cold and even turned her seat to low because she was so warm.
Here is a pic of where I tied it in at the engine. I used a thermostat bypass from Wide Open CO. And a Y off Amazon. I also added a couple extra shutoffs in case the core ever leaks.
I had to use 3/4" hose at the bypass due to the size of fitting. Every thing else is 5/8"
