Radiator Replacement cost
Radiator Replacement typically costs $520 to $1,150 at an independent shop, parts and labor included, and most shops book about 2 to 3 hours for the job.
The radiator sheds the engine's heat into the air passing through it. When it cracks or clogs, the engine can overheat, which is one of the faster ways to cause real damage. Most modern radiators use plastic end tanks that become brittle with age.
