Foregoing labor costs, the prices can vary depending on whom you buy the radiator from.
Save money at the radiator outlet. For years I had a small garage repair service, a resale license for auto parts purchases,s and accounts with numerous wholesale outlets. A girlfriend's Mercedes was in need of a new radiator due to poor coolant maintenance. Her longtime mech quoted $1500 parts/labor. A dealer sold the part for $900+. A local vendor that had a sales and installation facility sold me the very same OEM Behr brand radiator for less than $200. Installation was approximately an hour of my time including flushing the lines and heater core.
