2017-2022 Chevrolet Blazer OEM Radiator
Direct OEM replacement radiator for your Blazer's cooling system. Factory-spec core and tank design engineered to handle stock coolant flow and thermal load. Built to original equipment standards for seamless integration.
Do I need to drain and refill coolant when installing this?
Yes. Disconnect the lower radiator hose first to drain the system, unbolt the old radiator from its mounts, and swap in the new unit. Refill with your vehicle's specified coolant type and bleed air from the system per your service manual.
Will this work with my stock water pump and thermostat?
Completely. This radiator is engineered to work with factory cooling components—no swaps or upgrades needed unless your pump or thermostat is already worn.
