Hello all,
I took my viper out 2 weekends ago and after about a 1/2 hour of riding my heat light came on. I put in a little bit of bottled water to get me home and as soon I got home filled it up with staight coolant. I first got this sled last year and it seemed the temp light would fequently come on (I've never bled the system). Could it possibly be because it needs to be bled? The other reason I thought might be becasue the trails were very thin on snow so not much was kicking up to my coolers. One other note, prior to the season I took off one of the hoses in back of the seat as I was going to blead the system but then just put it back on and refilled the coolant so I could continue replacing the shocks, maybe I trapped some air in their and the circulation of the coolant is being restricted?
Any help would be greatly appreciated!

first off bleed the system and check the strength of your coolant sounds like you been adding this adding that your all over the map you don't need a mix more then -20 check it.
second add the rear heat exchanger will do wonders for that viper,try a search tons of info on that cooler issue,look for a cooler from a srx.
third ride when theres snow, : )
When I had to re-fill the coolant on mine, I pour some in and start the sled. I leave it at idle with the cap off and keep pouring till its full.

Add the rear heat exchanger plus protectors if running studs.

Bled the coolant per the manual, took it out for 45 minutes and no overheating. The only odd part was that when I went to bleed out near the carb heaters, no fluid came out? I removed the hose directly beneath the carb heater on/off vale and fluid came out? Per the manual, coolant should have flowed out of the screw location on carb heaters as well as the location in back of the seat. I just bought the sled last winter so I need to check if it already has the rear cooler......
Thanks

did you have the knob turned on?,, also you may need to pull the knob out of the rail some to get it too flow.
Vipers didnt have rear heat exchangers??

REAR HEAT EXCHANGER! Especially if you rid in cold icy conditions or conditions where there is no loose snow.
My sled was getting really hot too when the snow cover was thin. I don't have a rear heat exchanger so I put a set of the RSI ice scratchers on (in place of the 2nd wheels towards the front of the skid) and rode all day in very marginal snow with no overheating issues. $40 for the set, works for me.

scrathcers may be needed to compliment a REAR HEAT EXCHANGER!

I just did same thing to both of my vipers. Havent had a chance to ride yet so i hope it works as good as yours. I do have rear exchanger in both also. The RSI scratchers seem really nice, and a great price. Merry X-MASS!!!!

No rear heat exchanger. Just remember to pull those scratchers in when crossing roads or you'll grind them down in short order. Have fun
