Hello all now that i have got the extra money to get my new 500 i was wondering about overheating. My 400 is Liq. cooled also but i really never went hard core mudding, ya i did some mud but nothing deep. In MN we have soup like mud and i would like to know if any one evr has problems with getting there radiator all clogged up with mud and then driving down the dirt roads. I know this is some thing that happens on the polaris's because i have see it happen. Im just wondering. Also is there anyway of blocking the radiator better so less mud can get in while still being able to cool the big thumper. Im sure the winch palte will help, but i was just looking of more idea's. Also how can you water proof the head lights and why aren't they waterproofed. Thanks for your help/

 

sorry about the bad spelling. Im very tired.
Thanks

 

Stitch,
Aftermarket companies make louvers that fit on the Honda 250R ATV. The dimensions could be the same. This will allow you to protect your radiator from the mud and at the same time direct more air through the radiator to keep the motor cool. I have never done this but its just a thought that may work.

 

Living in Wi, we have pretty much the same conditions as you boys in Minn. I have never had mine overheat. You may want to add a off on swtch to the fan, or bring extra fuses. Mine every once and a while would blow the fan fuse when mudding in deep mud. Other then that no problem. I always tried to give my cat a river bath after riding in deep mud. But i think you should have no problem

When you are mudding in the soup the radiator will get clogged. Thick soupy mud+small fins=clogged. Mine started overheating going down the road. Pulled the radiator and it was almost completely plugged both sides, about 500-600 miles of trail riding with occasional mudholes. Not a big deal to clean, tip down the front bumper, take out the bolts, undo the hoses and pressure wash it out.

I think having the winch in front makes the overheating problem even worse becuase when going down the road, air flow is somewhat restricted, it is almost like putting on a winter front on your car. It might block some mud at high speeds, but most of the time you are just putsing through the thick soup and it just flows around and right into the fins. Aczr2k

 

Well mine has overheated too, but all I did was run a hose over it for about a half hour and it uncloged. I didn't even take it apart, but I don't have a winch either.

 

Boner:
Hey, what about your Rule? Have you not got the mounting plate yet, or just not hooked it up? -Oh, I guess maybe you meant you didn't have the winch when you overheated?

Sorry for the confusion, I knew you had a 3,300 lb. Rule-or at least used to.

I never mounted the Rule. I've been waiting on my dad go go pick up the peice of metal I need to weld on. He told me last night that he was probaly gonna be doing some welding today and to draw up plans and stuff. Well he didn't say anything this mourning so I guess thats not happening.

 

Becareful when using a pressure washer. the fins on the raidator are so soft that the pressure from the washer can bend them and not allow the air to flow through. When I had my 250R I was told never to wash the radiator because of that reason.

 

Yea, thats why I run a water hose on the radiator. It's just a steady flow of water over the radiator and it eats away the mud.
