I have a brand new 09 d8 dragon with the update it has about 300 mile and love the hell out of it but i just bought my wife a new 2010 700 rmk 155 and it warms up and ready to ride in like 10 min and the d8 take like 20 to 30 min to warm up anybody have an answer.
 
what do you mean by warms up? are you talking about water temps? you sled should take no longer than 5-10 minutes at an idle to warm up to operation temps between 100-120 degrees F. unless its like -30 degrees

might be your thermostat is stuck open.which will cause it to take a long time to warm up. you might try firing it up and feel the coolers while its warming up..if they start warming right up after a few minutes running it might be hung open.....
 
Start em up and keep it at idle until 70* then work the throttle under engagement until 100* and then ride the crap out of it. Within 100 yards of engagement when working correctly your buggy will be to 120-126 which is normal operating temp.

This isn't the issue but an FYI.
Just like already stated you should be able to feel the heat moving through the cooling system (touch both sides behind your seat bar supports to see if they are heating up and taking coolant). If your sled is not heating up on the rear coolers...with it running...open coolant cap... tip it on it side so that the coolant is the highest point and put it into reverse and run it a little bit...then forward....also a good idea to wiggle around the entire sled. This works a bubble out of your system. There is also a release screw (hex with flat tip slot) on the top of your head above the temp assembly housing. With the sled warmed up and the front elevated release this screw and coolant with air should spew out. All this ensures that your coolant system is purged of air bubbles and is good to go.
 
When i start my sled to warm up to go ride it take awhile likei said to warm but i will check it out on friday i have tried to get air out but i don't think there is any in the system but i see what happens on friday.Thanks guy's for all the input

If you had air in the system, it would have cooked it self in 30 mins of idling.

best way I have seen to get air out of the cooling system is to start sled while sitting on flat ground, tip sled up on right side while its running(like your side hilling)rev motor up until clutch almost engages, set it back down flat again recheck coolant level, then tip it up on the other side, rev it up again...then let it back down flat again..recheck level..this method when done 2-3 times will remove every bit of air in the system......
 
I will try all of this on friday to see if it helps it run's down the trail just fine as far as temps it don't hot stay's around 125 to 130 it is just the warm up to go riding that take's so dam long to me that is not right.
 
I would check the thermostat. From experience on trucks and sleds, if the water circulates to fast and runs wide open, it doesn't have enough time in the radiator or coolers to cool down.

AKSNOWRIDER,

Is this technique done with the bleeder screw open & the filler cap closed ?

Nice trick..

I crack the bleeder when I first fire the sled upthen close it once I get no air from it.....then put the cap down 1 click so it wont build pressure but wont leak..been doing them this way for years..and it works....

If you just start the engine and let it idle, it could take the Dragon longer to warm due to the large bleed hole in the stat. The large bleed hole is to allow coolant flow with the stat closed so you don't suck the inlet hose flat at high throttle openings with the coolant temp below 120. If you drive the sled at low throttle openings, it will heat up to 120 in a pretty short time, usually in under 2-3 minutes. What may deter you from riding the sled before the temp warms up is the retarded leanness that is programmed in the ECU. It's lean enough to cause surging and other annoying driveability issues until the sled warms up to over 70-80F (on my sled anyway). A guy (or gal) can fix this with a PC V but that may be a little spendy for this short duration driveability issue.

I don't think you have any air in the system but you can try the suggestions to practice the routine so it's familiar when you do crack the system open for repair or mods in the future.
 
well i worked the d8 today there is no air in the system when it was warming up it got to 75 degrees so i felt the rear cooler behind the seat and it was starting to get warm so i thinking that the thermostat is stuck open.

That would be my conclusion. Had kind of a similar problem on my duramax IT ran like **** when it was colder than 40 degris out, and took over 30-40 miles before it would get up enough heat to get the engine/tranny to shift out of 4th gear....

Swapped the thermostat and it takes 10 mins of idling to get warm. :face-icon-small-hap
