I have a 91 Indy 500SP and recently changed the coolant. I have had the sled running w/ the cap pressure relieve valve open and coolant between the min and max mar in the resvoir. Now the manual said this should relieve any air that is in the system, but I keep getting tiny bubbles through the hose that runs from the coolant neck back to the resivor. When I shut the pressure valve on the cap and let it run for a few min, then open the valve back up I keep getting air. I have had it running doing this for about 45 min, what gives? Is the tiny air bubbles spusto be there? Not to many at idle, but gets more as you rev it. Anyone run into this before?

Didd you lift the front of the sled up to get the air out of the heat exchangers under the tunnel? That usually helps, but if it isn't overheating, take it for a aride to get it flowing.
