2001 chevy express van/45,000 miles (purchased when new). Antifreeze leaking out because intake manifold gasket is leaking. Although svc. Bulletins/defect investigations exist for this problem, dealers service dept. States extensive cost to repair this is not covered by warranty or any chevy/gm warranty adjustment. Chevy customer (phone) assistance confirms this is a noted problem w/this vehicle's year/model but remains non-committal regarding covering costs to repair it for me.
