Do I need to drain the cooling system before swapping this in?

Yes. Drain the old coolant completely before removing the factory radiator. Once installed, refill with a 50/50 coolant-to-water mix appropriate for your vehicle. Bleed air from the system per your service manual.

Will the hoses from my old radiator connect directly?

Yes. This radiator uses factory connection points that match the original hose routing. Both inlet and outlet ports align with OEM plumbing—no adapters or modifications required.

Is this radiator pressure-tested before shipping?

This unit arrives assembled and ready to install. Before first use, inspect all hose connections and verify the radiator cap seats properly. Check coolant level after running the engine and monitor for leaks during the first few drives.
