I was riding my 07, 800R XRS the other day and when I stopped I noticed antifreeze dripping from the snow flap area to the ground, very small drip. I could not tell exactly where this leak was but it did not leak the rest of the day. Has anyone had good luck running radiator sealant in snowmobiles? Or is this just asking for trouble............. I plan on taking off the flap and checking the rear heat exchanger this weekend but if I cant locate the leak I was thinking of running some type of sealer theough the system.
