fan override rhino 700

Who has done it ? Does it help out. Whats the best way to do it?

yep it helps just dont run it when you hit mud

I have a fan over-ride on my Rhino 700.

In all honesty, I don't use it all that much. The fan keeps the motor running at the right temp. Once your engine starts getting a load on it and working hard and making some heat, the fan turns on (at ~205F) and runs continually until the engines cools down (~190F).

The only thing I have found the fan over-ride is good for is cooling the engine coolant below 190F. Even then, on a hot summer day in Texas, I can't really get the temp too much below 175F or so even if I sit there idling the motor with the fan on.

Who knows, maybe I'm using it wrong. LoL!!!

Where did you get that switch ? My bike runs around 210 on a hot day I just thought thats to high.

I got the switches from "The Switch Guys" over at OTRATTW

They have all kinds of ways to customize their switches with different color LEDs, SPST or SPDT or whatever. The LEDs can be wired independently like mine or just about any way you want. They have fast shipping.

You Rhino runs about the same temp as my 734 big bore. Just cruising on a how day it seems to run 200-210F. I even took my radiator out recently and cleaned it real good. It was dirty but no real changes in coolant temps.

So a fan override really would not help me.

I don't know. All I'm trying to say is that I haven't seen my temps magically fall to 160F when I run the switch in the summer. Maybe if you pull the thermostat, but I don't know if that's a good idea either.. These motors run hotter than I realized and hotter than most people around me realize. Yet the stock overheat light has never gone off.

My stock F150 is perfectly happy at 200F all day long. I know that's an apples to oranges but I might be comfortable saying modern engines, even small water cooled engines, are fine running 200F.

Putting that water temp gauge on my Rhino might have been the worst thing I've ever done... lol! I worry about it too much. lol!

I wouldn't just take my word for it. Lots of  people put in the over-ride switch.

175 is better than 210.lol..i feel its cooler in the cab when i run it

x2

You boys are a riot!

I can't get my temps too much below 175 unless I'm stopped and idling.  
That's with a clean radiator, engine ice, and the fan forced on.
I could be too dumb to work this thing right, though.  

Whenever I'm running down the trail in the summer, the temp wants to stay around 190-205F whether the fan is off or I have it forced on. I can get it lower but I have to stop for a few minutes and let the motor idle with the over-ride switched on.

Now in the cooler temps, it seems like I can do better by forcing the fan on.

But even then, the minute I start riding the motor wants to get up to operating temp pretty easily. It won't over heat or boil over; it never has not even once, it just wants to stay around that 190-200F spot. I suppose you could "pre-cool" the coolant if you could anticipate a long, hard pull with a big load on the motor in 4WD. Still, it seems like the coolant is going to get warmed up to the thermostat's rating quickly the minute the CVT starts backshifting and you put your foot into it.

I am [clearly] not an expert on cooling. I have the switch to force the fan on like many others do. All I'm saying is that it didn't do what I thought it would do, ie make my Rhino run 160F while I'm riding down the trail. I just haven't observed that, even forcing the fan to run continuously. The fan running continuously pulls a decent load on the electrical system, too. For some guys on the ragged edge of the stator's capacity the fan running constantly might be another consideration.

I'll be quiet now. lol

-1...lol

I Just bust out laughing!
Is this an admission of my boredom today? LoL

lmao C, I'm doing CV's right now, fun stuff...boring...wipe my hands, drink a beer, check the forum, with NFL network on in the garage....my secrets are out...lol

Most car thermostats are around 197*f, and the Rhino probably close to that, I don't know for sure, so a coolant is usually within 10 or so degrees cooler than the engine oil at operating temp.

You're not gonna get "magical" results running w/your fan continuosly on.  The numbers you are posting , are pretty close to what me , and everyone else I know w/a 700 are running.  Fuel injected engines , tend to run at high temps , than carb-ed engines...that's why we have t-stats,  to keep ours at a "constant" temp , and the 660's do not.  So...with the fan turned on , and running at a "normal" pace...175 is probably as low as you're gonna read ; but , like James said...175 feels WAAY cooler inside the cab , than 210 does !!

  I think a temp gauge should be everyones FIRST mod ,  since yamaha doesn't put them in , like most all the other mfgs do !!!

One bad thang about the fan on all the time is it's always sucking in dust and every splash of water turns it into mud.

Makes sense.

your is the only one that runs all the time..fix it teddy!!!!

i also have a heater so i have more coolant.. that makes a big difference...

Chris...i always like your input...

Thats ideal Temp wish it would stay like that year round it would make my beard more enjoyable. I long for frost in the beard all summer long!!

lol !!
