Polaris Sportsman Overheating! How to Troubleshoot Electrical Cooling System.

[@marywilson4445]

My problem was overheating intermittently on a 2008 sportsman. Finding the issue was difficult until the fan finally stopped working permanently . Your video was great and very helpful in diagnosing the problem. I went through all your steps and like you found it to be the circuit breaker. On the 2008 the circuit breaker is WELL hidden under the main fuse block and frame at the front of the machine. Not nice to get at. Anyone wishing to save a few bucks, the 10 amp breaker at a local automotive supply is 1/4 the price of Polaris part. Thanks again for the video

[@FishHuntCookTinker]

I am glad the video helped! I had a time finding mine and hoped to save others the hassle. I hate it wasn’t in the same location, but I am glad you were able to find it. It makes no sense why they hid the circuit breakers. Thank you for watching! I hope you don’t have any other issues for a long time.

[@Adventure_Lives]

I hope you continue posting videos like this. You’re an excellent teacher and did a great job walking through each step in diagnosing each circuit making no assumptions. A+

[@FishHuntCookTinker]

Thank you very much. I spent a lot of time making that video. I couldn’t find any videos breaking it all down. Just a little about this and that. It’s great to know it helped others with the same issues. Thank you for watching!

[@joefuria4344]

Thanks for sharing your video. You did the best job ever showing how to trouble shoot. I wish all others could be as understandable.🥇🙏

[@todddavis5470]

Just finished replacing the relay/fuse by the battery. Nice job on showing how to trouble shoot. I had no idea about this relay/fuse and would have taken ATV to the shop. Just subscribed to see what else you have to offer.

[@FishHuntCookTinker]

I am glad you found it helpful! That video took me forever to make. Thank you for subscribing!

[@Hammerback0]

Great job breaking down the instructions. I have an 05, which is nothing like yours, but I watched all the way through.

[@FishHuntCookTinker]

Thank you. I tried to break it down the best I could. Glad to hear you made it to the end! Thanks for commenting and watching!

[@reinardfourie4336]

Hi mate just thought I would let you know that your video was excellent and it helped me out a huge amount today.. I looked every where on the net and couldn't find any decent information. This video is top notch..

[@FishHuntCookTinker]

I am glad it helped you out! It took forever to make. It is nice to know it was worth it. Thank you for watching!

[@KD-xb3lx]

Great video I am at the coast in nc with my sportsman and had an overheating issue I always carry a tool sack and with your help and info I was able to get my fan running to finish my trip !! Thanks

[@FishHuntCookTinker]

That’s awesome to hear. I am glad it helped. Enjoy your trip and thank you for watching!

[@EdC197C]

I have been chasing this issue for like 2 years even wired a ma ual.switch to my fan and you saved me...it was my fuse under the air filter housing too!

[@FishHuntCookTinker]

I am glad it helped. Thanks for watching!

[@michellealms3238]

Was it saying hot all the time or intermittently?

[@staceywebb9943]

This video is spot on! Thanks for the in-depth diagnostic knowledge.

[@FishHuntCookTinker]

I appreciate that. I am glad it helped you. Thank you for watching!

[@dans4900]

This helped tremendously. I had the same problem. I checked the fan first than went to the easy parts first. Fuse, relay (just hear clicking) and than circuit breaker. Thanks for the video. Circuit breaker was bad. $10 part. Thanks again

[@FishHuntCookTinker]

I am glad it helped! Thank you for watching!

[@travisnoteboom9582]

Just did the same thing. Circuit breaker bad. Thanks so much for the help! Otherwise I would have had to find a good mechanic around here as the local Polaris dealer is a hot mess.

[@andyconnell7211]

Thanks for the awesome video. I had tested all the wiring up front, but did not know about the breaker/fuse under the air cleaner box. That fixed it just like yours!

[@FishHuntCookTinker]

I am glad it was helpful for you! It’s great to hear it fixed it. Thank you for watching!

[@luise2628]

Thanks for the video! I bought a 2013 Polaris Sportsman 500 recently and it was a hot mess with the wiring ! I fixed the majority of it and this was the last on my to do list, as you mentioned on the video it was the 12v 10 amp circuit breaker that was the issue...it was heavily corroded and power wasn’t getting through so I replaced it.

[@FishHuntCookTinker]

I am glad you found it helpful. Thank you for watching!

[@unknownwolf4046]

I have 2013 Polaris sportsman 400 h.o only problem I have now is radiator fan quit working after the voltage regulator was replaced same with radiator

[@jeremyjones4993]

This video helped me out sooo much! Thank you for making it! Saved me tons of time and money!

[@teddbragg970]

This vid helped me out tuns, prolly would never of figured it out without it, thank you so much

[@FishHuntCookTinker]

I’m glad it helped! Thank you for commenting!

[@kirkmckellar9350]

Great video. You did an excellent job explaining everything. I had no idea that circuit breaker was there. Going to subscribe

[@FishHuntCookTinker]

Thank you for the feedback. It’s awesome to hear it helped out. Thank you for subscribing!

[@shelleybaby9397]

Hey Awesome job all around!! Extremely helpful, gonna dig into my Polaris tomorrow!!

[@christorrey5484]

Wow, great diagnosis! I have a 2014 400 HO with the same issue...I'm going to see if this is the issue. I've been dreading having to load the parts cannon with all the other sensors and relays but if it is a simple fuse/circuit breaker that's easy to get to I'm all for at least trying to replace it. I'll post again to let everyone know if this fixed it. If not then it's off to the races with thermostat & other sensors. Fingers crossed.

[@christorrey5484]

That was it! Thank you so much! $10 from amazon and it's on the way. I removed that circuit breaker, tried to source it at NAPA and my locat ATV shop (who said that was on backorder for over a month) but ended up buying it from Amazon. I removed the circuit breaker, started up the engine and jumped the connection and bingo, fan is running again. Why Polaris would hide that part in that location is beyond me. Thanks again!

[@gmdonoghue]

Excellent video explaining the process - thanks heaps. One thing I don't get though - you confirmed that there was power to the relay, so how did the faulty circuit breaker cause it to not work? Does the circuit breaker cut off positive and negative cables?

[@FishHuntCookTinker]

To be 100% honest it has been a while since I traced all the wires out. If I remember correctly the circuit breaker was on the down stream side of the relay. The hot wire came to the relay then back through the circuit breaker. Then to the fan. The circuit breaker only controls the positive wire. Hope this helps. Thank you for watching!

[@terryschel3807]

Thanks I've currently got my fan hot wire to an on / off switch, having to replace it, after a hard ice bog hunting return trip, that turn my machine into a mud ice-cube. it also fried the regulator too.I have the coolant temperature switch, but I'll definitely check the fan relay and look for an overload in the circuit too. Rebuilding my winch at the moment too and rewiring everything, with watertight fuses as I go. Thinking maybe mounting the rad, up top, above the mud line, is a better idea, even if i loose the front cargo space.

[@FishHuntCookTinker]

I can only imagine what turning one into a “mud ice-cube” could tear up! I don’t think I could do without the cargo space. I am always strapping things down all over my wheeler. Good luck getting everything going again. Thank you for watching!

[@sixfourhim]

AT the 8:56 mark you say 20 amp relay for continuity but dont show where to connect, can you email me a definition of where to go with that?

[@sixfourhim]

[e-mail]

[@FishHuntCookTinker]

I miss spoke. I checked it at the 20 amp main fuse not the relay. Don’t know how I didn’t catch that when editing. You can see it at 9:00. I checked it at the fuse to check the integrity of the wire from the relay block to the main fuse. The wire goes from the battery. To the circuit breaker then to the fuse block. Ending at the relay block. I hope this helps.

[@ElPatronGamefarm]

I have a 2008 sportsman 500 h.o (non efi) with a fan that always stays on, even with the ignition off? Displays engine hot even tho engine is cold, any idea what it could be?

[@FishHuntCookTinker]

I have not run into that one yet. I would check the thermostat and relay. Something has to be stuck to send power even when the switch is off. Possibly the ignition switch.

[@ElPatronGamefarm]

@@FishHuntCookTinker where exactly is the relay for it?

[@nicolassambataro]

@@ElPatronGamefarm Hello! Right now I'm having the same problem on a 2005 sportsman 550. Were you able to find the fault?

[@ElPatronGamefarm]

@@nicolassambataro yeah it was the ecu

[@ivoryriffs88]

My radiator reservoir is boiling and bubbling out fluid. Any idea what that could be? Thanks

[@raysat7256]

Thanks. That's the same damn issue I have. The diagrams don't show this and having the sportsman down for Caribou season is not good.

[@FishHuntCookTinker]

I am glad it helped you out. Good luck hunting!

[@southernboys8272]

Thanks man your video solved my problem

[@FishHuntCookTinker]

Thank you for watching. I am glad it helped.

[@prietoPR809]

Well i replaced circuit breaker , relay and both sensors , fan still turns on when hot light shows on the panel. What could it be?

[@neilsutton5512]

Thanks for this video. Having the same issue with my sportsman.

[@FishHuntCookTinker]

You are welcome. Hope it helped!

[@johnnbw]

Thanks for sharing.

[@josejarillo6943]

2012 500 HO. Had same service message. Bypassed sensor that is on the radiator, the fan didn’t turn on at first but now turns on but “check engine hot” message is still on screen. Any input on what it could be???

[@FishHuntCookTinker]

My circuit breaker would go in and out. I would think I had it fixed. Then it would stop working again. Finally I changed the circuit breaker and solved my problem. You can temporarily bypass it just to be sure. Definitely wouldn’t run it that way, but works for troubleshooting.

[@kimtibben746]

Great Job....THANKS!!

[@jasonwulff8341]

Thank you very much. This is what I needed to check mine out.

[@davidbacon2470]

Was watching your video. My problem is that my four wheeler fan only turn on for 10 seconds and then turns off. The four wheeler begins to over heat later on and goes into a limp mode. The fan does kick on just for not very long..

[@davidbacon2470]

It’s a 2011 Polaris 850 sportsman.

[@FishHuntCookTinker]

Sorry for the delay. That is exactly what mine was doing in the beginning. Finally it would kick on once for a few seconds then nothing. Sometimes just nothing. Good luck! Thank you for watching!

[@outdooradventures6403]

I have a Polaris ace 570 and the fan won’t kick on and then it overheats because of the fan not kicking on what should I do?

[@FishHuntCookTinker]

I am not very familiar with the ace. It should be the same basic setup. Test you fuses, thermostat, and circuit breaker. If they are all good it may be a bad fan. Wish I could tell you more about them. I just have never worked on one. Thank you for watching and wish you luck!

[@lorierbar3624]

The best thanx so much Kevin Arnold Mo, saved me time n money, I owe u a 🍺

[@FishHuntCookTinker]

Glad it helped. I will hold you to it. Thanks for watching!

[@duuuuuudddeee]

Solid video man. I jumped straight to that circuit breaker and it saved me hours/days of hastle. Is there a theory on what frys it like that?

[@FishHuntCookTinker]

I am glad it helped you. I am not sure what makes them go bad so fast. Could be cheap or just a heavy draw for it. It seems to be a common thing. Thank you for watching!

[@captainrickyfla6170]

this is great video. thx for sharing

[@FishHuntCookTinker]

I am glad you liked it. Thanks for watching and commenting!

[@robinmills9278]

Why does my 2010 Polaris Sportsman overheat even when my cooling fan is on and working??

[@robinmills9278]

It also refuses to start once it quits from overheating until it cools down

[@josemiguel9899]

Thank you cool video really works for me 👍

[@FishHuntCookTinker]

I’m glad to hear that. Thank you for watching!

[@RRR-hj6bt]

2016 570 ranger. My problem turned out to be a bad ground. Everything is grounded under the fuse box under the drivers seat. Factory job is terrible, too many wires in each ring lug, poor crimp, and ground stud and frame are painted. My son could have done better when he was in the 5th grade.

[@duanethompson460]

Shut off that annoying music !!?&$$$&

[@unknownwolf4046]

Only problem with mine is radiator fan not working I did have voltage regulator replaced and radiator
