how does radiator come out from top or bottom on oldsmobile silhouette

Top. Here's are instructions on how to replace it, found it on an old discussion, hope it helps: At the bottom of the radiator will be a petcock, grab an old milk container and a funnel and drain the coolant, takin the cap off will make it drain faster...take the old coolant over to the auto parts store for responsible recycling..there will be two clips holding the top down...there will be two transmission cooler lines, take a sandwich bag and rubber band to stop them from dripping in the interim...there will be one or two thermal switches at the base...these must be unscrewed..there will be some coolant hoses top and bottom...sometimes they get stuck...even with an infusion of WD-40 are stubborn....use a "cotter pin installer" from sears with the L shape to fish it under the hose top and bottom, there is a smaller overflow hose near the cap as well---undo the top bolts the bottom should be held in with a some rubber U shaped holders....in review. drain coolant, disconnect tranny coolant lines, disconnect sensor wires, loosen two bolts holding the top on and pull up
