This morning I got this email from Jeff Coon.  Anyone have any ideas on this?     I recently purchased a new 2006 rhino. I went through the break in period, got it serviced. I then put on 27" itp 589 tires after that when I would ride about a mile the temp light would start coming on. I took it to the shop , they couldn't find anything wrong. I brought it back home and took the 27'' tires off. The temp light hasn't come back on since. I really want to run 27'' tires on it. Do you have any suggestions? Maybe a clutch kit or something?    Report

I put 26" Inovas Mud Gears all the way around my Rhino, 12's on the back and 10's and only had the temp light come on one time.  When I got home I checked between the cooler and the radiator and found some debris so I washed it out.  I also checked the overflow bottle and found it was right at the minimum mark so I filled it up.  Since then I've had no problems including running a 25 mile extreme endurance race in New Mexico. 06 Rhino 660 Innova Mud Tires Custom Rims Underhood and Cockpit lights Fog lights Custom built pre-runner/brush guard    Report

In fact I didn't know the rhino was supposed to be prone to slow rollovers, guess I shouldn't throw it around pucker bushes anymore, YEA HAAA! Maybe the little bigger tires than stock help stablize it some??

07-23-2007, 3:50 PM ag8tr1 Joined on 07-18-2007 Posts 4 Re: Big Tires causing Big Temperature? I have had my 06' 660 for about 3 months and it has 30" ITP mudlites on it. Almost every time I ride it has had the temp light come on, and overheated. I have tried cleaning the radiator, checked the overflow level, next I am going to bleed the line. The last thing I want to do is take the tires off it for smaller tires, especially with the 4" lift. Any other suggestions?    Report

Bigger tires make the wet clutch on these Rhinos work harder to get them moving, and that heats up the oil a lot faster. Increasing the size of your engine oil cooler will help disapate some of the extra heat. A better radiator, such as the one sold by Alba Racing will also help keep engine temps down. Be sure to change your engine oil frequently with those big tires, like every 20 hours or so. The engine oil is going to breakdown a lot faster with the extra heat, and the extra work load on the wet clutch. DV    Report
