CADILLAC DEVILLE ENGINE OVERHEAT

Car Keeps Saying Its Overheating When It Has Coolant And New Hose.

So Long Story Short. I Just Bought The Car Listed Above About 5 Days Ago. The Guy I Purchased It From Told Me That He Bought It 14 Years Ago...

Replaced Radiator, Water Pump, Thermostat, Radiator Cap. Flushed Entire System, Water Runs Clear And Flows Fully In All Directions....

Okay, So I Have A V8 Northstar Engine. It Has An Overheating Issue. I Can Fill Full Of Coolant And By The Time I Drive It Over The Bridge...
