A replacement radiator for a 2008 Suburban typically costs between roughly $300 and $1,000 in total, depending on whether you buy an OEM dealer part or an aftermarket unit, and on labor rates in your area. The radiator itself usually runs about $150–$700, with labor commonly adding about $150–$500.
Understanding what goes into that price helps explain why costs can vary. The 2008 Suburban offered multiple engine options and radiator configurations, and many radiators include an integrated transmission cooler. Availability of OEM vs aftermarket parts, aluminum vs copper/brass cores, and whether a shop bundles hoses, clamps, coolant, and a radiator cap all affect the final figure.

- Used or remanufactured radiator: $50–$250
- High-capacity or HD aluminum radiator (often with upgraded cooling): $450–$700
When selecting a radiator, verify compatibility with your engine and transmission configuration, and confirm whether the unit includes a transmission cooler.
Labor and installation considerations
