Hey everyone,
I drained all the coolant from my 03 viper and went to refill it and followed the bleeding procedure below.
I use the pressure gauge @ 14psi and bleed air from the rear heat exchanger screw, however when trying to bleed air/coolant out of the head bleeder bolt, nothing comes out. No air, no coolant.
I ran the sled to get it hot, about 5 mins@3000 RPM.
Should I see coolant come out of the head bleeder bolt when opening it? I took it completely out and nothing there. The carburator coolant switch it set to ON if that matters?
Really confused here.

I never pull out any screws other then the rear exchanger bleed screw. Elevate the front of the sled about 12" under the skis before filling and then crack rear bleeder screw until anti-freeze come out. Top it off, then run it and feel exchangers to make sure they are all getting hot. Let it cool down top off tank and good to go.
I do it like yamaha says, never had any problems. I usually leave the machine sit flat.
