Turbo coolant burping

[Danbot]

Hey guys
Looking for some advice! I'm finishing a Silber kit install with their belly intercooler setup on my 19 850RMK.
I don't seem to be getting any flow to the coolant hoses at the turbo. With the engine running and warm on the tunnel, main engine hoses, and bottle:
-not feeling any warmth on the turbo coolant hoses.
-if I loosen the easier to get at coolant fittings on the turbo, no coolant is squirting out of the loose fitting.

Any special techniques to getting the air burped out of the turbo / intercooler coolant system?

This morning I confirmed I had all the coolant hoses (turbo /intercooler kits) connected correctly. Still not getting warm hoses (from the PTO side head port to the coolant bottle is all cold while the large engine hoses and tunnel is hot)
Still stumped.

Same as any other one lift the front of the sled so it’s higher than the rear cooler and idle it with the rad cap off. Or let it sit over night with the cap off. I’m not near my 850 right now is there a bleed screw on top of the thermostat housing?
