how do you bleed the air pockets in the cooling system on a 1994 cadillac deville

 

There is no "bleed procedure" Early Northstars don't normally get air pockets; small hose/pipe that goes to top of surge tank purges air to tank. 03-05 tend to get them for some reason, which requires coolant to be topped of after 3-5 mile road test(after engine cools - of course).
