Check the radiator fins. Sometimes they get plugged with dirt, dust, and mud. Wash the radiator from the opposite direction of the air flow.Not the same direction as airflow. Also Highlifter offers a bigger and better flow radiator.Sorry I didn't see this sooner. Us 3rd shifters can't see a computor screen that well, in the sun light.:biggrin:

hey thanks for your input, i decided to ignore my dealers recommendation and pull the water pump apart the impeller was sheared off, no coolant flowing, so i ordered the parts today, one question i have is the water pump and oil pump are chain driven, but that chain seems super loose with no tensioner my dealer didn't even have a good view of this or any specs on chain tension, i dn't know if this had any thing to do with that or what? or if i should just replace it or what, thanks again.

Not sure about that question. Ronnies mail order has some pretty good pictures on it, In the oem replacement section . Also going to PM you about some other options.

Hey Buddy

Im new to hear, but found an old article of yours.

Did u have any luck with the loose oil pump chain?? I have an 03 model with an incredibly loose chain, sounds like it skips along while trying to start.

Can you please let me know how you went, or any info on whether I need to replace, or somehow tension??

Any info would be greatly appreciated.

Cheers

      Winch question?
      By Tim Keiper
      I have a Yamaha Timberwolf 4x4 250. I want to put a winch on it, but just wondering if the charging system will handle it or not ? Has anyone added one to their machine and have you had any issues?

      ATV Snow Plow Review, Best ATV & UTV Snow Plows
      By Ajmboy
      So we are almost a month into winter and I've been so busy working on my house that up until today, I didn't realize that we just haven;t gotten any real snow yet to warrant putting the plow on my grizzly. So that got me thinking, what are the latest plows out there and what ATV plows are the best? I've got 2 snow plows for my grizzly, a quadboss pile driver atv plow set up and a snowsport ATV plow. They are both a bit dated now and I tend to stick with the snowsport due to ease of use and I just like it so much. So if you have a plow on your ATV, please let us know what it is and post a picture with your atv/plow would be awesome. Would also like to know what you like and dislike about it.
      This is back a while when I did a write up on these 2 plows.... in 2009 I got the snowsport and in 2012 I got the quadboss.

      Winch ATV in to Truck Bed
      By Panupong Pradchaphet
      I have a Sportsman 450 HO and almost killed my self when loading it on my truck with ramps.  It rolled off the top of the ramps and tailgate and nearly landed on me.  I now want to winch the ATV in to the truck.  My question is are the front side bed tiedowns in my 2011 RAM strong enough to winch to without distorting the hooks or sides of the bed?

      I just bought a rare beast!
      By kawasig
      Hello All
      I'm kinda new to ATVs. I just bought a 1987 Suzuki quad runner 230 Dual Range. I'm having a problem finding info on it. It's very clean, only 2.800 miles. The front wheels are only 30 in.center to center. I was thinking about adding wheel spacers to give it more stability. I realize the added stress on ball joints and bearings. I'm wondering if there are any other concerns? Any input is greatly appreciated!

      2000 Grizzly 600.
      By Randomnumber73
      I'm working on my uncles grizzly and it sparks once on initial cranking then no more after that. If I let off the start button then press the start button again it will spark once then stop sparking. I was wondering if anyone seen this issue before.  Also I've never used forums before so sorry if this question is in the wrong location.
