Some of the parts came in but not all. I did get the thermistor and that is all working for now but I am not sure how long it will last. The plug got partly melted in the original overheat and it appears to be a bit fragile so we will see. I am not sure how to get another plug as I think it is listed as a wiring harness! I have never been able to actually contact anyone at Coleman so I don't know. I do know that if all else fails I can just put the jumper back on. BTW, my horn is working.

OK, a little follow up. I ordered all the parts but none have arrived as of this time. Closer exam of the plug to the thermistor revealed heat damage and testing of the thermistor showed it to be "open" and not to close at running temp. It is fried! I fashioned a jumper wire across the plug wires on the thermistor that can be easily removed once I get the parts. 😬The fan now runs whenever the power is on and it seems to be running smoothly. It hasn't overheated yet. The coolant fill went ok but it kept getting air in the circuit. Curiously, keeping the front end of the UTV up on a jack raised the front end and made this easier to do without getting the air. I did still have to use the air bleed screw at the motor.

I got the front compartment opened up somewhat, and running 12 V to the fan showed that it ran smoothly. I could find no fuses fried but I am not exactly which one powered it. I got the thermistor out (not too bad really!). I could run the test on the thermistor but I think it might be easier to just get a new one. They are apparently delicate so I'm hoping this is the problem. BTW, for future reference, the fuse box is under the seat. The manual doesn't really say where it is, or I just missed where it did, but there is a YouTube video out there that clearly shows it under the hood by the regulator in a Hisun, but in the Coleman version it is on the driver's side to the front, under the seat. I will order the thermistor and hopefully can get that sometime soon. Thanks for your help. I'll get back as soon as I get the part in. Hopefully this can help someone else too.

I was looking in the download section and can't find the manual. Is it the same as the Hisun 400?

That is awesome. Can't thank you enough. I'll get back as soon as I can check this out. Wish me luck. I'm going in. Hopefully I can get parts! Is it possible to get a service manual?

OK, I refilled the radiator and the reservoir and bled the system as suggested and that worked great! Unfortunately the idiot light came on again after 10-15 min and I think I realized then what the problem might be. The fan never did come on. Not at all. Perhaps a broken temp sensor or a bad fan? Relay? The water did circulate when I filled the radiator so the water pump must be OK

I'll try that before going any further. Thx!

BTW, Coleman UTV 400

OK, here's the mystery of the day. I was using the UTV the other day and the idiot light came on that said it was overheating. I immediately shut down and checked the coolant. No coolant! I refilled the overflow reservoir and the radiator and all was fine. 2 days later the light is on again. I rechecked the radiator and it was again empty? Bone dry? Now, here's the weird part, There is no coolant anywhere on the floor below the vehicle. I can't even see any on the frame. I have it up on the lift and am getting ready to start tearing into the bottom "skid plate" to see if the leak is in the hoses there. Any suggestions as to where to start? I have yet to begin and I am already baffled!

Is it possible that the dash unit has a manufacturing glitch?

Hey New, These things are a mess. I can't really describe what the plug looks like except it is white in mine. I followed the wires from the dash/fuel gauge unit to the first plug and this is it. Like I said, when I looked at it , it looked fine, but when I looked closer, there was a bent over tab inside. It was hard to see without a light. I reached inside the plug with some hemostats and was able to bend the tab back and then snap the plug back together. I wouldn't doubt if this was the problem with your speedo too. Tabs like this get bent when workers are rushed to get things done quickly. If all else fails, just start checking any plug you can get to. It is probably quicker and cheaper to do this than trying to contact warranty service. That was a nightmare! In all fairness though, once I got this little beast operating correctly, it has done very well.

I had the same problem when I got mine. I tried taking the tank apart and even got a new float and sensor. No luck. Warranty service was poor and very frustrating. I traced the entire wiring of it. No luck. As a last ditch thing I pulled the plug in the harness under the front hatch lid and it looked fine, until I looked closer! One of the little tabs in the plug was bent over. It would not contact but it still allowed the plug to snap together. The easiest way to find the white plug is to trace back from the dash gauge. You can straighten the tab with some hemostats and then plug it all back together. With all I went through trying to figure this out and the hassles I went through trying to get warranty service it would just make my day if this was your problem and it could be remedied as easily as mine was ((once I found it, that is). I agree, the tube is likely just a vent tube as everything on the tank locks in place.
