2009 Polaris RZR 800 radiator steaming

Recommended Posts

Been wrenching on a 2009 RZR 800. Took it out a couple times and the overheat indication came on. Found the coolant low. Filled and same thing happen the next day. When I run it at idle, steam pours off the radiator and it smells like glycol. No visible coolant leakage when it sits overnight. I suspect the radiator has several pin holes that retain liquid but leak when the coolant is vaporized. Can anyone else have experience with this?

Hey @Tim-ANC , with no leaks I would be concerned that the coolant is going into the combustion chamber. Is it smoking, white smoke? Check the water pump and make sure nothing is leaking.

Thanks AJM. Last week it overheated, steamed up and bypassed blowing coolant everywhere. Filled it up again today and did the air purge per the manual. No white smoke. I think it was low before. Will monitor. Still get steam off the radiator after it idles for awhile.

Radiator fan was not turning on. I did the test per the manual. While running, disconnect wire connector from the temp sensor near the thermostat. Fan is supposed to default to on. Mine didn't. Found the fan relay lose in the fuse box. Works great now.

      Went shopping on Saturday, picked up another Kawasaki Bayou 220 and a Yamaha Timber Wolf 250
      I really should sell some of these but they are a lot of fun to find, fix and ride
      Of course neither of them run but that's part of the fun!  Az

      Working on my oldest son's buddy's 2000 Big Bear.  He was having some power loss at WOT so i thought it worth while to clean the carb and put at kit in it...or at least clean the OEM jets and use the new orings that come in the kit.  It starts and idles like a champ, but dies and wants to backfire with any throttle at all.  I assume lean because it will run decent with the choke on. Air screw adjusted fine, nice crisp idle.  This one has fuel/air screw, low speed jet, mid jet, and main jet.  I was assuming just trash in the low speed circuit so pulled it and cleaned again, still does the same. 
      Two questions I guess:
      1. Does it sound most likely trash in the off idle circuit?  This one has a few more passages and jets than I'm used to...and a darn diaphragm.
      2. It now really wants to leak at the bowl drain screw.  It doesn't seem to tighten enough to completely stop the flow.  Seat looks good, screw was dirty but cleaned up fine with a touch of 2000 grit paper.  First for me.  Any idea here?

      So Id say about 2 years back I bought a 2013 Polaris Sportsman 500 H.O. off of my uncle. It ran perfectly, nothing wrong at all. I usually go mudding with it or just ride trails with buddies. So as you would assume, the quad is quite dirty from sitting for a few weeks.
       
      STUTTERING PROBLEM: I noticed one day out of nowhere that in high gear at 15-20 MPH, I was already maxed out at 4500-5000 RPM  It would get to 15-20 mph, max out on rpms and start sputtering. It sounded like it was basically acting like it couldn’t go any faster than this.
       
      IDLING PROBLEM: I was fucking with the carberator the other day maybe thinking that is causing my sputtering, and now my idle will shoot up to 2600 on start usually, then I will turn the throttle adjustment down to the normal 1400. The rpms with then fluctuate 10-30 rpms back and forth repeatedly, it will then run for about another 30-60 seconds and the RPMs will slowly drop to about 900-1000 RPM and stall out. I replaced the carburetor and everything seems to be working perfect on that, no leaks and what not but it’s still acting strange. Also, I’ve noticed that when looking into the Electronic Throttle Control that two plates that aren’t supposed to touch have to be WAY past touching to even try to fire up. Even when set at a wide open throttle like that, I still have to give it some throttle to get it to fire up.
       
      Here is what I have done so far: 
      Checked the belt and clutch
      Changed out spark plug (Last one was covered in carbon)
      Cleaned the intake and air box
      Replaced the carburetor
      Replaced the inline fuel filter
      Checked that all lines on carburetor are connected into the right spots
      Checked If intake boot was cracked (Not from what I can see)
      Unhooked and reattached new carburetor (About 4-5 times)
      Cleaned battery terminals and battery off
      Shut on and off Gas Line Cutoff Valve
       
       
       
      My next thoughts are that maybe the TPS is fucked up or maybe the Spark Arrestor is plugged with mud. I was thinking tomorrow to purge the exhaust and also check the ohms output on the TPS.
       
      ANY HELP IS GREATLY APPRECIATED. I HAVE BEEN BATTLING THIS FOR WEEK AND REALLY WANT TO GO RIDING. THANK YOU!

      Hi my linhai 300 is hard to start and  engages gears at idle which is 1200 rpm was looking at cdi says on it 7500 rpm does this mean quad should idle at 7500 rpm as this would explain transmission problemb as idle is too high thanks gary

      I wanted to share an experience and a fix.
      Headed out was following a pole line, was looking for a cross track that may take me to this speckle trout looking spot on a creek.  All paths and semi paths... failed.  Second objective was to reach a speckle trout lake that has been recently stocked... followed 1 trail to dead end, followed second trail to dead end.... while investigating options on foot and the quad idling it died.
       
      It wouldn't start.  eventually it did... and when it did … it was essentially a pinned idle.  activating the throttle did seem to speed it up but it wouldn't knock out of the racing idle.  couldn't put it in gear at that idle speed.  got towed out.
      when I first got the quad, I ran it off a trail and buried it pretty good in the soft snow... eventually winched out.  It wouldn't start.  eventually did and it was fast idling.  not as fast as this last time. but still fast.  it eventually seemed to settle and I got it in gear and by the time I was back to the truck was acting ok.  chalked it up to the bike being at a bad angle in the snow.
      My investigation last year lead to the throttle position sensor TPS.  how to jumper the diag block to see the sensor position on the display,.  I focused on this nearly sure it was a detuned sensor or broken sensor again this time.
       
      I tore down the front plastic and stuck my head into the TPS area to see what I could see.  What I found was that the throttle body assembly had actually come out of the mounting area (not sure what it is called).  the ring clamp was loose I could move it easily.  Hopeful, I tore down the air intake assembly above it (air filter...etc) removed a sensor clip and a hose.
      I backed off the clamp some more and was able to reseat the throttle body assembly.  put some blue lock tite on the clamp screw.  When I was cleaning off the air intake assembly to ensure I dropped nothing down the intake, I noticed the underside of the air intake "box" also had a clamp.  this screw was completely missing.
      I went to the hardware store, bought a metric replacement (brought clamp with me), seated the assembly, settled the clamp blue lock tite that as well... 
       
      quad fired right up, idled normal, idled up without hesitation and dropped right back off.  Cost of solution $3.87 CND for a pack of 5 metric screws.  moral of my story was don't assume an idle issue is a throttle position sensor problem... there are a number of other factors including air pressure, which I believe was my issue.
