Do I need to drain the cooling system before removal?

Yes. Drain the coolant into a container before disconnecting hoses or unbolting the old radiator. This prevents spillage and allows you to reuse the fluid if it's still clean. Refer to your service manual for coolant type and capacity.

Are new hoses and clamps included?

Radiator assembly only. You'll need to inspect your existing hoses for cracks or hardness before reconnecting them to this unit. If hoses show wear, replace them at the same time to avoid leaks down the road.

What if the mounting tabs or fittings don't align with my engine bay?

Test-fit the radiator in place before finalizing any connections. Factory radiators are built to OEM spec, but minor fitment variations can occur with age or prior repairs. Measure mounting points on your vehicle against the assembly before committing to bolts or hoses.
