1995 chevy silverado 4x4. 350. Overheats after <2 miles. Top hose collapses, bottom cooler. flows from cap to overflow and back. New radiator, hoses, water pump, thermostat, radiator cap, 2 temp sensors, and coolant.
also new clutch fan.
Possible head or intake gasket? Or there is a large blockage somewhere. When cold take the rad cap off, start the truck and watch the open radiator. Hit the gas a couple times and see if it starts spewing out the radiator within 30 seconds. If so you have a head gasket issue.
