has any one heard of an overheating problem with the 05 Rincon after going thru heavy mud? I got this unit to replace my rubicon for the IRS and extra power, but it will over heat even just putt putting around after going thru mud. I never had this problem with my Rubicon, and this last weekend I took them both out, put them thru the same test and it happened again,Rincon ran hot , Rubicon just fine. yes both radiators were covered with mud but only the Rincon ran hot.

 

Mine did the same thing right after I got it, I checked the plug a few times and it was kinda white-ish so I assumed I was running lean, causing the machine to run a little too hot. Not hot enough for the light to come on during normal riding but when I hit the mud and clog the radiator it would come on. I was already getting ready to re-jet and add a pipe so after I did all that I adjusted the carb to run a little rich. It took me a little while to get the rejetting right but now my machine never overheats. I hit a couple mud holes and rode 90 miles at Hatfield McCoy a few weeks back, no problems whatsoever.

There are some mods to help with overheating, but they would just be masking the problem so I would get yours checked out before doing these.

1. Fan override switch - allows you to keep your fan on all the time, when you want.
2. separate the oil cooler from the radiator by adding spacers, washers, etc - some say the design traps mud between the radiator and the oil cooler, causing overheating. If you separate them more, air can get in and you can clean it better too.
3. add water wetter or engine ice coolant, something like that.

Either way, there are many many Rincons that never overheat in the mud so there is some issue with your bike, if it's under warranty, take in to the shop.

Good luck!

 

Thanks for the info, it has be back and they say there is nothing wrong, but they cant do anything more then an Idle test and test the sensors. I will try the spacers to help not trap the mud. I'll let you know how it works!!
