Overheating sidewinder

[Kyle24]

I bought a new sidewinder a couple of days ago. It currently has 9 miles on it and has overheated 15 times. The dealership had it twice today. The first time they thought it had air in the system. After they got done with it it seemed fine. I put a couple miles on it and it overheated again. They then replaced the thermostat. Again seemed fine for a few miles but overheated again. Anybody have any ideas of what could be causing this?

Snow and a set of scratcher should help .The other problem is the rear flap not on the ground directing snow back to the track .Mine over heats on hard pack but not with the scratchers i made for it .

Hmmmmm, something up. I've had zero issues. For starters, make sure the coolant isn't 100% coolant.

These machines are extremely sensitive to snow condiotions. What was the snow like?

Some guys have no issues and others like yourself are having overheats. It really does sound like an air lock.

How about the water pump itself

Or sending unit. Is it really that hot?

No picture ,but i used the spi wheel relocater kit and the ice storm rail mount scratchers .This setup works great .Look up sm-12551-1 adapter kit

Like some already stated,ice scratchers,and check anti freeze,mine was mostly straight,so mix 60/40% and add a qt of water wetter,also set up the front end above the rear,about 1foot in the air,and crack coolant cap,run for a few min. to make sure air is not trapped.

Mostly straight on the Winder Pete?
How about your son's? Mostly straight as well?

Not sure how you ride or the conditions you were in but we have a a couple guys have problems running hot when 1) slow constant speeds with out snow kicking up 2) extreme hardpack without scratchers. 3) sit and idle to long.

These sleds stay much cooler when varying the throttle. When stopped as well as running at slow speeds. Studs help on hard pack as well.

They need to get the snow flap dragging also .

Just picked mine up tonight brand new backed it off the it ran for about 4 minutes she shut off overheated. 15 degrees out at that time. We went riding it would stay around 5/8 to 3/4 on the temp. Just got in it's 5 degrees out and plenty of snow. LTX-SE something can't be right.

reheating issue maybe caused from the antifreeze itself.It maybe to concentrated(not enough water mix to thin out to displace the heat).100% straight will retain heat longer than mixed with water.Had same issue with a few new Yamaha sleds I ownedso I drained some antifreeze and added water to a 75% mix,meaning 25% water and issue was resolved never had problem again.For some reason Yamaha uses straight antifreeze when the sled is built.I am willing to bet that maybe your issue.

I just put on over 1,200 miles in the past 5 days in eastern Ontario . I overheated 5 or so times. Had to manage heat carefully at times and seek off trail snow several times. At other times, I had to shut it down going down roads that were too well plowed. Waited a few minutes and pressed on.

Other times, the snow became overly tight frozen with temps as low as 27 below and the sled would not kick up enough snow to hit heat exchanger. Areas of fresh grooming only made matters worse. Had to seek snow and goose it to flip up snow.

Winders appear to cool down very quickly once snow hits the exchanger.

My experience is to shut down sled if you are going to be stopped for more than 2 or 3 minutes. If not, it will overheat no matter how cold the air temps are.
