Do I need to drain the cooling system before installation?

Yes. Disconnect the negative battery terminal first, then drain the coolant into a clean container. You'll need to remove both hose clamps and disconnect the upper and lower radiator hoses. Have towels ready for spillage.

Will the fans and shroud bolt directly to this radiator?

Factory shroud mounting tabs align with the OEM radiator. The electric fan harness plugs into the same location—no rewiring needed. Verify bracket orientation before tightening to avoid contact with the fan blades.

What coolant should I use when refilling?

Use the coolant type specified in your vehicle's service manual. Mix it with distilled water according to the concentration listed, then fill slowly through the radiator cap opening to avoid air pockets. Burp the system by running the engine with the cap off until coolant stabilizes.
