Just purchased a 21 model 800 yesterday. Put it in the shed yesterday had stuff to do. Jumped on it this evening and took it easy just riding around the yard. 5 mins in the coolant temp warning is going off. Checked coolant and added 1/2 gallon. Ok whatever. My son wanted me to see a trail he had been working on next door so I followed him in. Nice and easy nice wooded trail.  30-45 mins in same thing. Let it cool down he went back for antifreeze. Topped it off another 1/2 gallon. Took it straight home and put it up.  Rechecked coolant. Low again. Noticed a substance hitting the floor. As a mechanic I know this ain't good. Pulled the dipstick and there is all my antifreeze. 3.5hrs on machine and only 12 miles. Never been over 30mph and never been hammered on. Wtf!!??

Looks like you'll be getting your second new one.

Don't let them fix this one for you. Have them replace it immediately.

Agreed...have it replaced completely.

That's what I'm gonna be fighting for. Machine had 1 hr on it when I loaded it up at the dealer. Has 3.5 hrs on it now.  I love it. Its smooth and powerful. Comfortable enough to ride all day without needing advil and some muscle cream at the end of the day. Gotta wait a couple more hours for the dealer to open then we will have our little chat

Dealer is replacing the wheeler tomorrow. Delivering a new unit and taking old one back

Great to hear that they took care of it for you.  Enjoy new machine #2.
