2014 RZR 800s Overheating Problem HD 1080p

[@GaryMiller-os9ks]

What I did was I put a funnel in the radiator an put anti freeze in it, I hooked the front of the range toy gantry hoist and with come along. I lifted the front off the ground 12" to 16" tires off the ground. I started up the engine and let it go through the water temp cycle. I saw air bubbles around the base of the funnel, but never used any of the out of the funnel. I let it cycle a couple of times. I let it down and reinstalled the cap. It was good since.

[@Pitlane326]

Ok I gotta try that, thank you

[@kengilmore4384]

Put green in it

[@julioalbertorodriguezperez9137]

It might be the pipes under the carriage that connects the radiator to the engine

[@rebeccaconnors9918]

I had a similar issue, I cracked the hose that connects to the motor behind the oil filter and blead out the air that way

[@Pitlane326]

I like that, I'll have to try

[@enriquecampos3395]

Have you already solved the problem? mine is the same and I can't find a fix😢 Rzr 800. 2009

[@victoriaprusak5364]

Watched your video and I would say it's a head gasket sending compression into the cooling system. Most lively a warped head due to overheating. Hope this helps. VICTORIA

[@usernoivalido6800]

Cuantos grados es la temperatura perfecta para rzr 900 ?

[@edwincordero1810]

You have air in the lines

[@Pitlane326]

Doesn't overheat while driving and bled the air out, so don't know what it is.

[@MSGmining]

Mostly air in system, bleeding air have to be from engine, next to injector 8mm bolt

[@casmitherz]

Some engines have bleed screws to vent the system when servicing coolant. Worth a look through the service manual. I've had this problem with a different engine.

[@foothillsjim3980]

Temperature sensor is in the engine which is HOT. When you turn it off the coolant quits circulating through the radiator and the engine heats it up - which is where the sensor is. And that is what you are showing. Coolant does not boil at 212 degrees - more like 223 degrees for 50/50, and higher under pressure.

[@Pitlane326]

I understand what you're saying, but funny how it never did it when it was new and started before I flushed it for the 1st time and changed the fluid. I'm sure being hot as hell out here doesn't help. To me it's a shitty design and the head or top of engine should have a return line back to the radiator just like a car or truck, air rises!!

[@classicxl]

Mine is a little bit of a pia to start back up after the engine is hot and i shut if off to take a break. sometimes it takes 2-3 times to get it to stay running

[@Pitlane326]

That could be all sorts of things, bad gas, plugs, air cleaner, low compression.....

[@goodolsouthernboy352]

My 2010 is doing the exact same thing. Have you figured out what's doing it or how to fix it?

[@Pitlane326]

What I did and do is forget making sure the overflow bottle is filled, the radiator always has full fluid. Don't know why this is. I set the digital dash to temp so I can see what temp it's running at. Never boils while riding but when it does get to 204 the fan kicks on and temp drops to 180's. When I get back from a ride, I turn it off then turn key on and watch the temp climb to 204 or over , then start it, fan turns on and temp drops to 180's and then turn engine off and I'm good. I'm totally lost on why it does this but at least I have a cure. Also install an override switch so you can turn fan on at anytime, this switch does not interfere with the fan normally working, you can find these on amazon for about $50.

[@Pitlane326]

And... not sure if yours does this but the fan on mine does not turn on unless engine is started. I alway thought it did but don't remember when it was new. I also run Preston 50/50 all vehicles in the yellow bottle, screw what the dealer says.

[@kuauhtliguerrier9036]

Hello my fan dosn't turn off, always is on, what could it be? Thanks

[@Pitlane326]

The only thing I can think of is either the relay is bad or the rubber cap fell off the sending unit. If by chance the stock wiring and or switch was altered by someone could also be the problem.

[@jamiecarroll3231]

Mine is doing the same thing it's a 22 1000 XP high lifter. Also the temp gauge keeps going up and down.

[@Pitlane326]

Must be a crappy design we have, cars and trucks don't have this problem. Having to bleed air out tells me the water intake/outlet are in the wrong spot. Definitely one should be on the top of the engine because air rises. Hope you can figure yours out.

[@TheBakeryBoys]

Sounds like head gasket issues

[@SlipKnotTom]

Yup lol

[@charleswbaker4310]

Water in the oil, white smoke?

[@trentonidom677]

You’re supposed to let your fan run after turning off your side by side until it turns off

[@Pitlane326]

Only problem with that is the fan doesn't run until the engine is started, turning the key doesn't do it. Maybe that has something to do with it?

[@ETInc-cu1yv]

Having this problem right now have you still not figured it out?

[@Pitlane326]

Have not figured it out, only overheats when I turn it off, I don't get it. 2 things I did is leave overflow bottle empty and added a fan override switch so you can turn the fan on anytime, cost $50 on amazon, comes with a rocker switch and plugs into the wiring harness, does not interfere with the fan turning on normal. Works great for summer time. If you fgure this out please share because this RZR will never see a dealer. $$$

[@MasterBuilderofTruth]

Head gasket, make sure and deck the heads, these are known to have leaks

[@sherifali1442]

​@@MasterBuilderofTruthit the head gasket and he need to check the head of the cylinder may be swollen from the heat

[@paprecisiontv1635]

Behind the passenger seat there a big bolt behind that there’s a 8mm Allen screw is the bleeder for the coolant system crack it and let all the air out of the system if the radiator is cold but the engine is hot this is more than likely the problem

[@Pitlane326]

I did that while is was not running and while it was running until no air came out. I might change that screw to a hose and valve for easy access.

[@2551adrian]

@@Pitlane326 Does it still overheat after you bled the air out of it?

[@Pitlane326]

@@2551adrian Yes, only when I shut off the engine

[@2551adrian]

@@Pitlane326 Thank you. I will give it a try. I have the same issue.

[@mikemcgee6810]

I have the same problem but only when I ran the machine hard uphill in 4 low. First time it did this. The engine shut down! I just had to wait it out so it would cool down. Replaced the water pump 3 years ago. Again, never had this problem. I know one thing I’m gonna do, and that’s replacing my air filter. Still had the original in on this 2015🤣🤣🤣

[@StarknightMT_official]

Are you interested in product testing? About drive belts and UTV license plate holders for your RZR 800s.

[@jovanemontes80]

I am

[@GaryMiller-os9ks]

It has air trapped in the engine

[@Pitlane326]

If it does how do you get it out??? Obviously the little screw doesn't work that Iv'e tried many time as mentioned in this video.

[@mooreokla718]

I have my fan run all the time

[@jeraldvickery4166]

I must join this club 2014 800 overheats every time I try to go for a ride.

[@Pitlane326]

I don't get it either, I want to put a clear hose with a valve I can open on the little screw on top of the head to see if air is in there. Everyone says it's air in the lines that causes the overheating.

[@Pitlane326]

Hey the override fan switch works great, don't have to wait for the fan to kick on at 204, easy to install and cheap.

[@jerrycordova1971]

Have you figured this out yet?

[@Pitlane326]

Not sure, I leave the overflow bottle empty and it hasn't done it. Tested the original thermostat in a pot of water and it opens up at 180 so I put that one back in. For some reason the fan does not turn on with the key on, only runs if the engine is started.

[@garvinhooper]

have you removed the fan relay for any reason,if so make sure its plugged back in the right slots

[@Pitlane326]

@@garvinhooper Only removed the 1 relay and replaced with a new one. Never removed any other fuses, but I've always wondered if they make a relay that will turn on at a lower temp? Not sure if the relay regutates the fan temp on and off.

[@Pitlane326]

It's in the 60's here, went for a ride, ran great and did it again once I got back and turned it off. I restarted, fan kicks on and temp drops to 188 and turn it off. I'm lost

[@cainearnest7419]

I’m having same thing going on mines a 2014 800 crew

It’s normal my rzr 2013 lik it I have it before 3 years No problem ❤
