660 Rhino Overheating and losing Coolant

[tmurphy]

Hey there;
I have an '07 660. I'm overheating and losing coolant. When i let the machine idle and heat up I can't see any visible leaks of coolant. The fan comes on as it should. But when i take it for a drive, the heat light comes on and i'm down coolant?????? If i was burning coolant wouldn't I see white smoke coming out the exhaust? Any ideas would be greatly appreciated.

Did you check your oil to make sure it's not milky? Could be leaking into there.

Clean the rad it may "look" clean but you have to see right through it make it work. Put a trouble light behind should see right through I can read stickers through my rad a never had a problem

Possible air lock in the cooling system, ending up taking mine to dealer to figure this out on mine, had the exact same symptoms, I was convinced it was the water pump and they had it fixed in 10 min. (I felt stupid.)

-jack up front end a bit
- Fill rad cool to top
- turn on engine
- open bleed valve on water pump (do not remove just loosen) located on the bottom of the engine passenger side just follow the rad hose. once fluid burping out at a even rate close.
- repeat same steps on driver side, top of engine, follow rad hose to thermo housing.
- keep rad full all the time while doing it.
- rev engine occasionally during process.
- shut down
- re-cap
keep overflow bottle hooked up properly and filled.
- good to go.

This is why I was overheating,.. I also added a TCP fan shroud while I had the rad out.

I did and the oil looks fine.

Rad is clean.

You pulled your rad and checked it?
