There is no definitive answer as the cost of a radiator can vary significantly depending on the make and model of your vehicle, as well as the style and size of the radiator that you need to replace. However, using OE parts typically costs around $297 while aftermarket parts tend to be cheaper, typically costing around $88. Additionally, labor time for radiator replacement can range from around 0.9 hours to 2.0 hours, meaning that the total job cost will again vary greatly depending on which option you choose.
