The average radiator repair cost tends to be between $400 and $600. However, the cost will vary depending on the standard price of labor for automotive professionals in the area. Other considerations as well, including the cost of the radiator itself, must be factored in. For example, trucks and SUVs tend to have larger radiators, which cost more. Radiator repair may also mean the various hoses attached to the radiator must be replaced as well. The typical cost of the radiator itself is usually $150 to $250.
