My cooling fan seems to run a lot anyone else notice this with theirs?

I can't say I have had any trouble with my fan running a lot. Do you ride in a lot of mud or real dusty areas? If you do then I would make sure I washed the heck out of my radiator. I ride in muddy and dusty areas all the time and when I wash my radiator off I spray water back through it from the fan side. I hope this helps and i hope you find out what's wrong

 

[Gunner73]

Not really dusty and no mud but the fan seems to run a lot. It seems like the fan did the same in my Teryx 4 as well but I can't remember.

 

[Ben]

Well, I'm at a loss then. I hope you figure it out.

Not real sure but maybe your viking is running lean. There was a tread on here with a bunch of people who were having trouble with there's running lean. Just an idea

ive been also told that it depends on what weight of oil you're using will affect the temperature as well. On my grizzly I went from 5w40 to 20w50 and it seemed to me the fan was on less. just finished break in and put 20w50 in it(Viking). with only 2.2L of oil I figure it would hurt. just need to let it warm up slightly before moving it. not the greatest weather in Canada. not used in the winter

 

[Ben]

That would make since. In fact I would have to check the book but in think they do list different weight oils for different riding temps.

Punch out the catalytic converter. Your engine will run way cooler and the fan won't be running as much. If you have a heater installed it will take a little while longer to get heat. The engine will take longer to get up to the 180 degree mark. Compared to my rzr s the fan did run more on the viking before I gutted the cat.
