Brand New 700 and it Overheats in 5-10 minutes...HELP

We just bought a brand new Rhino 700 and brought it home today. While driving it at low speeds to break the engine in, the overheating light came on. We cut the engine off and immediately heard a sizzling sound. On inspection of the radiator and coolant we found it boiling over. After letting the engine cool of for about 10 minutes we started the engine again and in about 5 minutes it overheated again. We stopped and left the Rhino to sit for a while, then when riding it later it did it again. We noticed that the fan has never came on and can only figure that that is the problem but are unsure of the underlying issue. Why is the fan not coming on? We checked the fuse, it looks fine, checked the wiring and wiggled some things around, and they all seem fine. That's about as far as our knowledge of these machines go. Of course, we are going to call the dealer first thing Monday morning to get this fixed, but until then, we'd just like to know what the problem could be?

In addition, we started it and let it idle in our driveway and in about 5 minutes the overheating indicator light came on!

If it's brand new I wouldn't even mess with it I would take it back to the dealer.

I was reading on a different forum, that a guy bought a brand new 2011 dirtbike. Took it home, put gas it it, and rode it down the block. With in a few minutes, he said that he heard a weird noise and the engine locked up. Well when the dealer prepped the bike, they forgot to add the oil. Needless to say, he got his money back.

We checked the oil and coolant before. It was all there. We are definitely going to call the dealer and have them repair it. We are just baffled as to why it did this. There is supposed to be a checklist that the dealer has to go through before selling a unit and I am sure that checking to make sure the radiator fan is in correct working order would be one thing that they SHOULD check but I guess not in this case. It hasn't come on one time since we have had it.

It sounds like the coolant system needs to be burped, maybe from the train ride to your dealer.

Yep, definitately sounds like the dealer missed something in dealer prep. A lot of times those guys just want to get the prep stuff over with....and they are human, they do make mistakes. Your new Rhino should NOT be overheating......let us know what they say!

The exact same thing happened to me. I bought my 2012 700 two weeks ago, and it kept overheating and I noticed the fan not turning on. Dealer picked it up and checked it out and the plug to the fan was not getting a good connection. One of the metal pins in the plug was bent, so they straightened it out and plugged it up and fan now operates. Must have been the same slacker on that section of the assembly line

I just got back from my dealer with heating problems and anti-freeze overflowing. Second time he's had it. Trouble is with the thermostat. Found to be bent the first time and was replaced. Within two weeks had the same trouble and found thermostat bent the second time. Dealer suggested removing it to be sure that the heating problem and he will get with Yamaha next week to see if they have a solution.
