overheating 08 outy 800

[brpjunky]

My bike overheats, and the rad is 90% clean, there maybe some mud caked in the corners but nothing major, the overheating happens even when I'm driving down a clean trail. Is there any mods that I can do to fixe this problem?

Welcome to the site My last Outty started overheating all the time too and I thought for sure the rad was spotless but it turned out that I needed to remove the rad and soak it then give it a good rinse. Cured mine. Have you tried sticking a flashlight behind it and making sure you can fully see through it? You might be surprised on just how a 10% plugged rad can make your quad run hot. It might just be a faulty sensor too?? Good Luck.

check and see if the cores are swoll up,my 06 got pulledout of 3 rallies the cap on the overflow melted and couldnt releive pressure and when it overheated it expanded the cores thus no room for air to come thru
jmo good luck............

Several people have this issue and not just on the outlanders. My renegade is fine though, no real overheating issues. I would do what the others suggested, and pick up some "water wetter" from JB's or Mopac and add 1/2 of it to the system, not the full bottle as this is for a car. Also another trick Ive seen is some peeps have added a switch that they can override the fan and you can have that running when you want.

are you losing any coolant? make sure to check that your coolant level is up. these water pumps are notorious for leaky seals. Service bulletin is available through your dealer if this is your problem.

Yeah thats something that i would look into.. we have at least 2-3 a week in the shop here with overheating issues, and we do that waterpump recall and never a complaint
after on overheating.. we see a lot of units here and thats usually the issue. at BowCycle South

I'm having overheating issues also, going to remove rad soak it and change the wiring on the fan so that it will blow on the rad and not try to pull air through it. Let you know how I make out.

I wouldn't change the fan, that'll basically stop any cool air from the front from going through the rad when you are driving with fan running.

Ya but I think it would make a cool noise when your cruising down the road at like 80k ... ever Blow into a fan.

But seriously I wouldn't do it. Are you snorkled??? What size of snorkles? Does it go into Limp Mode when its hot or just a light comes on. Good chance its your rad. Maybe a little plugged. A good soak will definatley not hurt them.

I hadn't considered that benefit....Baseball cards in the spokes obviously wouldn't work.

A guy on another forum had over heating problems with his renegade and could not find the problem..... until the dealer found out that the fan had been wired to run in the wrong direction ( it was blowing air through the rad instead of sucking the air)
After they rewired it to run in the right direction no more overheating issues.
