Does this radiator come with fans or mounting brackets?

Radiator assembly only. You'll need to source your cooling fan and shroud separately, and verify your existing brackets align with the tank outlet locations before install.

Can I use this with my current water pump and hoses?

Hose ports are standard small-block sizing. Your existing pump will work. Test-fit the hose runs before final tightening—some aftermarket engine blocks may require slight hose routing adjustment.

Should I flush the system before connecting this radiator?

Yes. Run fresh coolant through the block and engine bay to remove old sediment, then fill and burp the system normally. A clean system keeps the new aluminum core performing at full capacity.
