No sign of anti-freeze anywhere. Nothing dripping, nothing under the muffler, nothing on the floor. The level even went down while trailering. The dealer can not find anything. Is it likely to be an air pocket in the system? Pressure test was perfect. Any ideas???

My antifreeze level dropped twice when my sled was new, I'm thinking it was just air in the sysyem. Another thing to check... remove the muffler & see if it melted through the "T" in the cooling system. Mine melted, but not all the way through when the sled only had 100 miles on it.

my brother went for a trip to moosenee he was losing antifreeze no sign of it anywhere he went 1050 miles but needed to go 1065 fst seized 15 miles from trucks head gasket failed.his was a 2007 dealer he bought it from was with him on his trip,long story short he is getting a new 2008 motor no charge
